Similarly, the history information storage unit 130 associates the message number “002” with the destination user ID “ID_B”, the sender address “a001@sss.com” as the first header information, and the subject as the second header information. “S-BBB”, transmission time “March 1, 2006 13:00” as third header information, destination address “b001@xxx.com” as fourth header information, body information “BBBBBBB (with attached file) ) ”And the opening flag“ 0 ”are stored. Similarly, the history information storage unit 130 associates the message number “003” with the destination user ID “ID_B”, the sender address “a001@sss.com” as the first header information, and the subject as the second header information. “S-CCC”, transmission time “March 1, 2006 17:30” as third header information, destination address “b001@xxx.com” as fourth header information, body information “CCCCCC”, and opening flag “0” is stored. The message number is an example of identification information for uniquely identifying an electronic mail to be transmitted, and is numbered by the transmission unit 100. The message number and the destination user ID may be included in the header information.

  The unsealing notification receiving unit 110 counts when the unsealing notification about the e-mail transmitted from the transmitting unit 100 to the terminal device of the user B with the user ID “ID_B” is received from the transmission destination terminal device. The number of opened mails in the information storage unit 120 is increased by 1. For example, an opening notification about the information notification mail transmitted to the terminal device of the destination address associated with the application time zone by the transmission unit 100, and the message number and the destination user ID of the information notification mail When the opening notification including “ID_B” is received from the terminal device, the transmission time which is the third header information associated with the message number of the information notification mail included in the opening notification by the history information storage unit 130 is set. It is determined whether or not the reception time of the unsealing notification is included in the application time zone including the transmission time among the application time zones associated with the destination user ID “ID_B” in the total information storage unit 120. If it is determined that the message is included, the opening number stored in the history information storage unit 130 in association with the message number is opened. Increasing the opening already mail number stored in association with the applicable time zone and the destination user ID "ID_B" In summary information storage unit 120 and updates to "1" indicating only one.

  The transmission means 100 at the end point of the first application time period in the e-mail transmitted to the user B whose destination user ID is ID_B in a certain application time period (first application time period) by the transmission means 100 The number of transmissions and the number of opened emails are acquired from the total information storage unit 120, a number notification email containing the acquired number of transmissions and the number of opened emails is created, and the next application time zone after the first application time zone In the second application time zone, the number of transmissions and the number of opened emails are sent to the terminal device of the destination address associated with the second application time zone by the total information storage unit 120 by the number notification mail. To do. Then, the number of transmissions is increased by 1 and the number of transmissions is notified among the number of transmissions stored in the total information storage unit 120 in association with the destination user ID “ID_B” and the second application time zone, and the presence / absence information of the number notification mails. Update the presence / absence information of mail to information indicating "Yes". In the example illustrated in FIG. 5, when the application time zone “10: 0 to 17:59” is the first application time zone, the application time zone “18: 0 to 23:59” is the second application time zone, and the total is calculated. The information storage unit 120 stores the number of transmissions “1” and the presence / absence information “Yes” of the number notification mail in association with the destination user ID “ID_B” and the second application time zone “18:00 to 23:59”. This indicates that the number notification mail is transmitted to the terminal device having the destination address “b002@yyy.com”. The transmission means 100 transmits the number notification mail to the destination address “b002@yyy.com” corresponding to the second application time period “18: 0 to 23:59”, and the number of transmissions in the total information storage unit 120 and When the number notification mail presence / absence information is updated, in the second application time zone “18:00 to 23:59”, the first application time zone “10: 0 to 17:59” and the destination user ID “ ID_B ”is stored in the history information storage unit 120, the number of transmissions, the number of opened mails, and the presence / absence information of the number notification mails, the number of transmissions“ 0 ”, the number of opened mails“ 0 ”, and the number of notifications It is preferable to reset the presence / absence information to “none”.

  The storage medium 80 stores a program for causing the computer to perform processing operations of the transmission unit 100, the opening notification reception unit 110, the total information storage unit 120, the history information storage unit 130, the mail queue 150, and the clock unit. The mail server 10 including a computer may cause the processing operations of the means 100 to 150 such as the transmission means 100 and the clock means to be performed by installing the program stored in the storage medium 80. Further, as another method, the mail server 10 may acquire such a program through a network.

  FIG. 6 is a flowchart showing an example of processing operation of the mail server 10. FIG. 7 is an explanatory diagram showing an example of the number notification mail. This flowchart starts from a state in which the mail server 10 monitors reception of securities transaction information, which is notification information to be notified to the user B from the securities transaction information providing server 12 and the related information providing server 14. Further, at the start of this flowchart, the total information storage unit 120 stores the information shown in FIG. 3 in which the number of transmissions and the number of opened mails are all 0 and the presence / absence information of the number notification mails is all “None”. Suppose you are.

  The transmission means 100 determines whether or not the securities transaction information to be notified to the user B has been received (step S100). When it is determined that the securities transaction information to be notified to the user B has been received (step S100: Yes), the transmission unit 100 creates an information notification email to be transmitted to the user B based on the received securities transaction information. To do. In this case, the transmission unit 100 assigns a message number for identifying the electronic mail, and creates an information notification mail including the message number and the user ID “ID_B” of the user B. Next, the transmission unit 100 acquires the email address of the user B corresponding to the application time zone including the current time from the total information storage unit 120. For example, when the current time is 11:00, the transmission unit 100 refers to the destination user ID “ID_B”, the application time zone, and the destination address stored in the total information storage unit 120 to determine the current time The electronic mail address “b001@xxx.com” of user B corresponding to the applicable time zone “10: 0 to 17:59” including “11:00” is acquired. And the transmission means 100 transmits an information notification mail addressed to the terminal device of the acquired electronic mail address (step S110).

  Subsequently, the transmission unit 100 stores the transmission history of the information notification mail transmitted in the predetermined application time zone in step S110 in the history information storage unit 130, and for the application time zone and the destination user ID “ID_B”. The number of transmissions associated with the total information storage unit 120 is increased by 1 (step S120). For example, the transmission means 100 sends the e-mail address “b001@xxx.com” of user B associated with the applicable time zone “10:00 to 17:59” including 11:00 at 11:00. An information notification mail addressed to the message number “001”, the subject “S-AAA”, the transmission time “March 1, 2006 11:00”, the destination address “b001@xxx.com”, and the body information “AAAAAAA” In the case of transmission, the transmission means 100 associates with the message number “001” in association with the message number “001” and the sender address “a001 @ sss” as shown in the upper part (first record) of FIG. .com ”, subject“ S-AAA ”, transmission time“ March 1, 2006 11:00 ”, destination address“ b001@xxx.com ”, text information“ A ” Stores AAAA "to the history information storage unit 130. However, in step S120, the transmission unit 100 stores information “0 (initial value)” indicating unopened information in the history information storage unit 130 instead of “1” shown in FIG. Further, the transmission unit 100 transmits the transmission time associated with the application time zone “10:00 to 17:59” including the transmission time 11:00 and the destination user ID “ID_B” in the total information storage unit 120. Increase the number by 1.

Next, the transmitting means 100 determines whether or not the opening notification receiving means 110 has received the opening notification mail indicating that the electronic mail transmitted in step S110 has been opened (step S130), and determines that it has not been received. In this case, the process proceeds to step S150. If it is determined that the receipt has been received, step S150 is performed after the process of updating the opening flag of the email corresponding to the opening notification mail by the opening notification receiving unit 110 to “1” (step S140). Proceed to
For example, the transmission unit 100 sends a receipt confirmation instruction including a user ID “ID_B” to the receipt notification reception unit 110 as a receipt confirmation instruction of the receipt notification. When the receipt notification receiving means 110 receives the opening notice of the information notification mail from the terminal device, it temporarily holds it in the internal memory together with the reception time, and when receiving the reception confirmation instruction from the transmission means 100, the user ID included in the reception confirmation instruction It is determined whether “ID_B” matches the destination user ID of the information notification mail included in the opening notification held in the internal memory. If they do not match, the unopened notification information including the user ID “ID_B” is transmitted. If there is a match, the transmission time which is the third header information stored in the history information storage unit 130 in association with the message number of the information notification mail included in the matching opening notification is acquired, Of the application time zones associated with the user ID “ID_B” in the aggregate information storage unit 120, If the reception time of the opening notification is included, and if the reception time is not included, the unnotified information of the opening notification including the user ID “ID_B” is returned to the transmission means 100 and the reception time is included. Updates the opening flag stored in association with the message number in the history information storage unit 130 to “1”, and corresponds to the applicable time zone and the destination user ID “ID_B” in the total information storage unit 120. In addition, the number of opened mails stored in addition is increased by 1 (step S140), and the reception notification reception information including the user ID “ID_B” is returned to the transmission unit 100. When receiving the unsealed notification information including the user ID “ID_B” from the unsealed notification receiving unit 110, the transmitting unit 100 determines that the unsealed notification has not been received (step S130: No), and proceeds to step S150. When the receipt notification reception information including the user ID “ID_B” is received from the receipt notification receiving unit 110, the process proceeds to step S150.

  In step S100, when it is determined that the securities transaction information or the like to be notified to the user B has not been received (step S100: No), the transmission unit 100 aggregates the information in association with the destination user ID “ID_B”. The application time zone including the current time is detected from the application time zones stored in the information storage unit 120 and is stored in the total information storage unit 120 in association with the application time zone and the destination user ID “ID_B”. Get the number of sent messages and the number of opened mails. Then, it is determined whether the number of unopened mails obtained by subtracting the number of opened mails from the number of transmitted mails is greater than 0 (step S105). If the number of unopened mails is greater than 0, the process proceeds to step S130, and the number of unopened mails If is less than or equal to 0, the process proceeds to step S150.

  In step S150, the transmission unit 100 refers to the application time zone and the current time stored in the total information storage unit 120 in association with the destination user ID “ID_B”, and determines whether or not the next application time zone has been reached. to decide. In the example illustrated in FIG. 3, when the current time is 18:00, the transmission unit 100 transmits the application time zone “10: 0 to 17:59” to the next application time zone “18:00 to 23”. : 59 ”. If the transmission means 100 determines that the next applicable time zone is not reached (step S150: No), the process returns to step S100. If the transmission unit 100 determines that the next applicable time zone has come (step S150: Yes), the transmission unit 100 proceeds to step S220.

  In step S220, the transmission means 100 creates a number notification email containing the number of emails sent and the number of opened emails sent in the previous application time zone, and sets the destination address corresponding to the current application time zone. Send to terminal device. In this case, in the example illustrated in FIG. 3, the transmission unit 100 first sets the current time “18:00” in the application time zone stored in the total information storage unit 120 in association with the destination user ID “ID_B”. The current application time zone “18: 0 to 23:59” included is detected and stored in the total information storage unit 120 in association with the application time zone “18: 0 to 23:59” and the destination user ID “ID_B”. To the stored destination address “b002@yyy.com”, the application time zone “10: 0 to 17:59” immediately before the application time zone “18: 0 to 23:59”, and the destination user ID “ID_B” The number of transmissions, the number of opened emails, and the presence / absence information on the number notification emails stored in the total information storage unit 120 in association with each other are acquired. The first condition in which the number of transmissions is “1” and the presence / absence information is “present” (that is, only the number notification mail is transmitted to the user B in the immediately preceding application time period), or the number of transmissions is “ It is determined whether or not the second condition of “0” (that is, a state in which no email is transmitted to the user B in the immediately preceding application time period) is satisfied. When the first or second condition is satisfied, the transmission unit 100 does not perform the process of transmitting the number notification mail and ends the process of this flowchart. When the first and second conditions are not satisfied, a message number for identifying the number notification mail is assigned, and the corresponding destination address “b002 @ yyy.” Is applied in the applicable time zone “18: 0 to 23:59”. com ”is transmitted to the terminal device of“ com ”, the number notification mail including the message number and the destination user ID“ ID_B ”in the header information and the number of transmissions and the number of opened mails in the body information. In FIG. 7, as an example of the number notification mail, the header information of the number notification mail includes the message number “004” of the number notification mail and the address “a001@sss.com” of the mail server 10 that is the sender address. , Including the subject “number of emails”, the transmission time “March 1, 2006 18:00”, the destination address “b002@yyy.com”, and the destination user ID “ID_B”, and the text information of the number notification email As shown, an e-mail including “the number of transmissions in the time zone 10: 00 to 17: 59 (including one opened mail)” is shown. For the time zone “10: 0 to 17:59” in the text information, the detected current application time among the application time zones stored in the total information storage unit 120 in association with the destination user ID “ID_B”. The application time zone “10: 0 to 17:59” immediately before the zone “18: 0 to 23:59” is used. Next, the transmission unit 100 stores the number of transmissions and the number notification mail stored in the total information storage unit 120 in association with the destination user ID “ID_B” and the current application time zone “18:00 to 23:59”. Regarding the presence / absence information, the number of transmissions is increased by 1, and the presence / absence information in the number notification mail is updated to information indicating “present”. The transmission unit 100 then associates the history information with the application time zone “10: 0 to 17:59” and the destination user ID “ID_B” immediately before the current application time zone “18: 0 to 23:59”. The number of transmissions, the number of opened mails, and the number notification mail presence / absence information stored in the storage unit 120 are reset to the transmission number “0”, the number of opened mails “0”, and the presence information “none”. The process ends.

  As described above, according to the mail server 10 of the above-described embodiment, when the user B uses a plurality of notification destination e-mail addresses according to the time zone, the first terminal device corresponding to the first application time zone is used. The second terminal device corresponding to the second application time zone can be notified that there is a transmitted electronic mail. In addition, by notifying the second terminal device during the second application time period, the number of e-mails transmitted to the first terminal device during the first application time period and the number of opened mails among them are notified. The number of transmissions transmitted to the first terminal device during one applicable time zone and the number of opened mails thereof can be notified to the user B through the second terminal device, and the user B can determine the number of transmissions and the number of opened mails. It is possible to recognize whether there is an unopened mail from the difference.

  In step S220, the transmission unit 100 at the end of the applicable time period in the e-mail transmitted by the transmission unit 100 to the terminal of the user B immediately before the applicable time period “10: 0 to 17:59”. The header information of the unopened mail may be acquired from the history information storage unit 130, and the acquired header information may be added to the number notification mail and transmitted. For example, the transmission unit 100 includes the current time March 1st, 2006 at 18:00 including the date in the applicable time zone stored in the total information storage unit 120 in association with the destination user ID “ID_B”. The application time zone “10: 0 to 17:59” on March 1, 2006, which is the application time zone immediately before the application time zone “18: 0 to 23:59” on March 1, is detected, and the destination user The first to fourth header information stored in the history information storage unit 130 in association with the ID “ID_B” and the opening flag “0” is acquired, and the third of the acquired first to fourth header information. It is good also as a structure which transmits the header information contained in the application time slot | zone "10: 00-17: 59" of March 1, 2006 which detected the transmission time which is header information by the number notification mail.

  Further, in step S220, the transmission means 100 is transmitted in the previous application time period instead of the number notification mail including the number of e-mails transmitted and the number of opened mails transmitted in the previous application time period. A configuration may be adopted in which a number notification email including the number of unopened emails, which is obtained by subtracting the number of emails sent from the number of emails sent, is transmitted to a terminal device having a destination address corresponding to the current application time zone. In this way, the number of unopened emails, which is the difference between the number of emails sent to the first terminal device in the first application time zone and the number of opened emails among them, is the second application time zone. By notifying the terminal device 2, it is possible to notify the user B through the second terminal device whether there is an unopened electronic mail in the first terminal device. As an example, the text information of the number notification mail may be set as “number of transmissions in time zone 10: 00 to 17:59: 3 (of which 2 are unopened mails)”. The service provision period for providing the notification service by repeatedly executing the processing shown in the flowchart of FIG. 6 may be set by the user B from the terminal. For example, the user B can set the service provision period from the terminal in units of one month. You may do it.

  FIG. 8 is a block diagram illustrating an example of a block configuration of the mail server 10 according to another embodiment. 9 and 11 are explanatory diagrams illustrating an example of information stored in the aggregate information storage unit 220 in another form. FIG. 10 is an explanatory diagram illustrating an example of information stored in the history information storage unit 230. Hereinafter, the mail server 10 in the other embodiment will be described.

  As shown in FIG. 8, the mail server 10 includes a transmission unit 200, an opening notification reception unit 210, a storage unit including a total information storage unit 220 and a history information storage unit 230, a mail queue 250, And a clock means. The clock means provides information indicating the current time to the transmission means 200, the opening notification reception means 210, the total information storage section 220, the history information storage section 230, and the mail queue 250.

  The total information storage unit 220 stores a plurality of e-mail addresses of the same user, an applicable time zone in which each of the plurality of e-mail addresses should be used, and an address classification of the plurality of e-mail addresses in association with each other. Each of the plurality of e-mail addresses is stored by being classified into either a main e-mail address or a sub-mail address. The total information storage unit 220 may be configured using a relational database (RDB), and includes a destination user ID field for storing a destination user ID for identifying a destination user of an email, and an email address. An application time zone field for storing information indicating an application time zone to be used, a destination address field for storing an email address of a destination to which an email is transmitted, and an address classification of the destination email address. Address classification field for storing, sent number field for storing the number of e-mails sent in the applicable time zone, and the number of read mails that are the number of open notifications received for e-mails sent in the applicable time zone For the number of saved mail count fields for storing emails The number of notification mail presence / absence fields for storing presence / absence information indicating nothing is provided for each record, and the destination user ID, application time zone, destination address, address classification, number of transmissions, and number of opened mails stored in the same record And the presence / absence information on the number notification mail may be associated with each other.

  In the example illustrated in FIG. 9, the total information storage unit 220 associates the user B with the user ID “ID_B” and the application time zone “10: 0 to 17:59” and sets the destination address “b001@xxx.com”. The address classification “main”, the number of transmissions “3”, the number of opened mails “1”, and the presence / absence information “none” of the number notification mails are stored. Further, in correspondence with the user ID “ID_B” and the applicable time zone “18: 0 to 23:59”, the destination address “b002@yyy.com”, the address classification “main”, the number of transmissions “0”, and the opened mail Stores the number of cases “0” and the presence / absence information “none” of the case number notification mail. Further, in correspondence with the user ID “ID_B” and the applicable time zone “00: 00 to 09: 59”, the destination address “b003@zzz.co.jp”, the address classification “sub”, and the number of transmissions “0” are opened. Stores the number of completed emails “0” and the presence / absence information “none” of the number notification emails. Note that the total information storage unit 220 may acquire and store information about the destination user ID, application time zone, destination address, and address classification from an external storage medium, or may be input by the operation manager of the mail server 10. These pieces of information may be stored. The address classification “main” indicates that the destination address is a primary mail address, the address classification “secondary” indicates that the destination address is a secondary mail address, and the address classification of the personal computers 22 and 32 is the primary mail address. The address classification of the mobile phone 42 may be a secondary mail address.

The transmission means 200 acquires securities transaction information and the like to be notified to the user B, and creates an information notification mail based on the acquired securities transaction information and the like. Further, the transmission unit 200 refers to the current time and the total information storage unit 220, and acquires an e-mail address that is a destination address corresponding to the applicable time zone including the current time. Then, the transmission unit 200 transmits an information notification mail to the terminal device of the electronic mail address, and stores the number of transmissions stored in association with the destination user ID “ID_B” and the application time zone of the information notification mail. Increase by one.
Furthermore, when the application time zone is switched and the e-mail address corresponding to the current application time zone is a sub-mail address, the transmission unit 200 determines the number of e-mails sent in the immediately preceding application time zone and When a notification email containing the number of opened emails is sent to the terminal device with the secondary email address, and the email address corresponding to the current application time zone is the primary email address, the previous application time Of the e-mails sent to the band, an unopened e-mail is re-sent to the terminal device of the main mail address. The mail queue 250 is for temporarily storing electronic mail transmitted by the transmission means 200.

  The unsealing notification receiving unit 210 receives an unsealing notification mail indicating that the e-mail has been unsealed from the terminal device of the e-mail address to which the e-mail has been transmitted by the transmitting unit 200. For example, when the transmission unit 200 transmits an information notification mail to the personal computer 22 with the electronic mail address “b001@xxx.com”, the opening notification reception unit 210 sets the personal computer 22 with “b001@xxx.com”. To receive an opening notification mail about the information notification mail.

  The history information storage unit 230 stores, as history information, header information and body information of the email transmitted by the transmission unit 200, and an opening flag indicating whether the email has been opened, Stores an initial transmission flag indicating whether it is an initial transmission mail or a retransmission mail. The history information storage unit 230 may be configured using, for example, a relational database (RDB), and includes a message number field for storing a message number that is identification information of the transmitted email, and the transmitted electronic A destination user ID field for storing a user ID of a mail destination, a first header information field for storing a sender address (source address) which is first header information of the transmitted e-mail, and transmission A second header information field for storing a subject (title) which is the second header information of the transmitted electronic mail and a transmission time (transmission time) which is the third header information of the transmitted electronic mail. And a destination address which is the fourth header information of the transmitted e-mail. A fourth header information field for storing (destination address), a text information field for storing text information of the transmitted e-mail, and whether or not opening information has been received for the transmitted e-mail An opening flag field for storing an opening flag to indicate and an initial transmission flag storage field for storing an initial transmission flag indicating whether or not the transmitted e-mail is an initial transmission mail are provided for each record. The message number, the destination user ID, the first to fourth header information, the body information, the unsealing flag, and the initial transmission flag stored in may be associated with each other. The initial transmission flag is, for example, “1” when the electronic mail is the first electronic mail and “0” when the electronic mail is the retransmitted electronic mail.

  In the example illustrated in FIG. 10, the history information storage unit 230 associates the message number “001” with the destination user ID “ID_B”, the sender address “a001@sss.com” as the first header information, the second Subject “S-AAA” as header information, transmission time “March 1, 2006 11:00” as third header information, destination address “b001@xxx.com” as fourth header information, and text information “AAAAAAA” ”, An opening flag“ 1 ”, and an initial transmission flag“ 1 ”are stored. Similarly, the history information storage unit 230 associates the message number “002” with the destination user ID “ID_B”, the sender address “a001@sss.com” as the first header information, and the subject as the second header information. “S-BBB”, transmission time “March 1, 2006 13:00” as third header information, destination address “b001@xxx.com” as fourth header information, body information “BBBBBBB (with attached file) ) ”, An opening flag“ 0 ”, and an initial transmission flag“ 1 ”. Similarly, the history information storage unit 230 associates the message number “003” with the destination user ID “ID_B”, the sender address “a001@sss.com” as the first header information, and the subject as the second header information. “S-CCC”, transmission time “March 1, 2006 17:30” as third header information, destination address “b001@xxx.com” as fourth header information, body information “CCCCCC”, unsealing flag “0” and the initial transmission flag “1” are stored. The message number is an example of identification information for uniquely identifying an electronic mail to be transmitted, and is numbered by the transmission unit 200. The message number and the destination user ID may be included in the header information.

  The unsealing notification receiving unit 210 has received the unsealing notification for the first transmission mail out of the e-mails transmitted to the terminal of the user B of the user ID “ID_B” by the transmission unit 200 in a certain application time period from the transmission destination terminal device. In this case, the number of opened mails in the total information storage unit 220 is increased by one. For example, an opening notification about the information notification mail transmitted to the terminal device of the destination address associated with the application time zone by the transmission unit 200, and the message number and the destination user ID of the information notification mail When the opening notification including “ID_B” is received from the terminal device, the transmission time that is the third header information associated with the message number of the information notification mail included in the opening notification in the history information storage unit 230, and The first transmission flag is acquired, and the reception time of the opening notification is included in the application time zone including the transmission time among the application time zones associated with the destination user ID “ID_B” in the total information storage unit 220. If it is determined that the message number is included, the history information storage unit 230 stores the message number in association with the message number. When the opening flag is updated to “1” indicating opening and it is determined that the opening flag is included, when the initial transmission flag is “1”, the total information storage unit 220 applies the applicable time zone and the destination user ID “ID_B”. The number of opened mails stored in association with is increased by one.

  The transmission means 200 at the end point of the first application time period in the e-mail transmitted to the user B whose destination user ID is ID_B in a certain application time period (first application time period) by the transmission means 200 The number of transmissions and the number of opened mails are acquired from the total information storage unit 220, a number notification mail containing the acquired number of transmissions and the number of opened mails is created, and in the application time zone following the first application time zone In a certain second application time zone, the number of transmissions and the number of opened mails are transmitted to the terminal device of the destination address associated with the second application time zone in the aggregate information storage unit 220 by the number notification mail. . Then, the number of transmissions is increased by 1 and the number of transmissions is notified among the number of transmissions stored in the total information storage unit 220 in association with the destination user ID “ID_B” and the second application time zone, and the presence / absence information of the number notification mails. Update the presence / absence information of mail to information indicating "Yes". In the example illustrated in FIG. 11, if the application time zone “10: 0 to 17:59” is the first application time zone, the application time zone “18: 0 to 23:59” is the second application time zone, and the aggregation is performed. In the information storage unit 220, the number of transmissions “1” and the presence / absence information “number” of the number notification mail are stored in association with the destination user ID “ID_B” and the second application time period “18:00 to 23:59”. This indicates that the number notification mail has been transmitted to the terminal device having the destination address “b002@yyy.com”. The transmission means 200 transmits the number notification mail to the destination address “b002@yyy.com” corresponding to the second application time period “18: 0 to 23:59”, and the number of transmissions in the total information storage unit 220 and When the number notification mail presence / absence information is updated, in the second application time zone “18:00 to 23:59”, the first application time zone “10: 0 to 17:59” and the destination user ID “ ID_B ”is stored in the history information storage unit 220, the number of transmissions, the number of opened mails, and the presence / absence information of the number notification mails are set to the number of transmissions“ 0 ”, the number of opened mails“ 0 ”, and the number of notifications It is preferable to reset the presence / absence information to “none”.

  The storage medium 80 stores a program for causing the computer to perform processing operations of the transmission unit 200, the opening notification reception unit 210, the total information storage unit 220, the history information storage unit 230, the mail queue 250, and the clock unit. The mail server 10 including a computer may cause the processing operations of the means 200 to 250 such as the transmission means 200 and the clock means to be performed by installing the program stored in the storage medium 80. Further, as another method, the mail server 10 may acquire such a program through a network.

  FIG. 12 is a flowchart showing an example of processing operation of the mail server 10 of FIG. FIG. 13 is an explanatory view showing an example of the information notification mail to be retransmitted. This flowchart starts from a state in which the mail server 10 monitors reception of securities transaction information, which is notification information to be notified to the user B from the securities transaction information providing server 12 and the related information providing server 14. In addition, at the start of this flowchart, the total information storage unit 220 stores the information shown in FIG. 9 in which the number of transmissions and the number of opened mails are all 0 and the presence / absence information of the number notification mails is all “None”. Suppose you are.

  The transmission means 200 determines whether or not securities transaction information to be notified to the user B has been received (step S300). If it is determined that the securities transaction information to be notified to the user B has been received (step S300: Yes), the transmission means 100 creates an information notification email to be transmitted to the user B based on the received securities transaction information. To do. In this case, the transmission unit 200 assigns a message number for identifying the electronic mail, and creates an information notification mail including the message number and the user ID “ID_B” of the user B. Next, the transmission unit 200 acquires the email address of the user B corresponding to the application time zone including the current time from the total information storage unit 220. For example, when the current time is 11:00, the transmission unit 200 refers to the destination user ID “ID_B”, the application time zone, and the destination address stored in the total information storage unit 220 to determine the current time The electronic mail address “b001@xxx.com” of user B corresponding to the applicable time zone “10: 0 to 17:59” including “11:00” is acquired. And the transmission means 200 transmits an information notification mail addressed to the terminal device of the acquired electronic mail address (step S310).

  Subsequently, the transmission unit 200 stores the transmission history of the information notification mail transmitted in the predetermined application time zone in step S310 in the history information storage unit 230, and for the application time zone and the destination user ID “ID_B”. The number of transmissions associated with the total information storage unit 220 is increased by 1 (step S320). For example, the transmission means 200 sends the e-mail address “b001@xxx.com” of user B associated with the applicable time zone “10:00 to 17:59” including 11:00 at 11:00. An information notification mail addressed to the message number “001”, the subject “S-AAA”, the transmission time “March 1, 2006 11:00”, the destination address “b001@xxx.com”, and the body information “AAAAAAA” In the case of transmission, as shown in the upper part (first record) of FIG. 10, the transmission unit 200 associates the message number “001” with the destination user ID “ID_B” and the sender address “a001 @ sss”. .com ”, subject“ S-AAA ”, transmission time“ March 1, 2006 11:00 ”, destination address“ b001@xxx.com ”, text information“ AAAAA ", stores the initial transmission flag" 1 "to the history information storage unit 230. However, in step S320, the transmission unit 200 stores information “0 (initial value)” indicating unopened information in the history information storage unit 230 instead of “1” illustrated in FIG. Further, the transmission unit 200 transmits the transmission time associated with the application time zone “10: 00 to 17: 59” including the transmission time 11:00 and the destination user ID “ID_B” in the total information storage unit 220. Increase the number by 1.

Next, the transmission means 200 determines whether or not the opening notification receiving means 210 has received the opening notification mail indicating that the electronic mail transmitted in step S310 has been opened (step S330), and determines that it has not been received. In this case, the process proceeds to step S350. If it is determined that the mail has been received, step S350 is performed after the process (step S340) of updating the unsealing flag of the e-mail corresponding to the unsealing notification mail to “1” by the unsealing notice receiving unit 210. Proceed to
For example, the transmission unit 200 transmits a reception confirmation instruction including a user ID “ID_B” to the opening notification reception unit 210 as a reception confirmation instruction of the opening notification. When the receipt notification receiving unit 210 receives the opening notification of the information notification mail from the terminal device, it temporarily stores it in the internal memory together with the reception time, and when receiving the reception confirmation instruction from the transmission unit 200, the user ID included in the reception confirmation instruction It is determined whether “ID_B” matches the destination user ID of the information notification mail included in the opening notification held in the internal memory. If they do not match, the unsealing notification unreceived information including the user ID “ID_B” is transmitted. If there is a match, the transmission time which is the third header information stored in the history information storage unit 230 in association with the message number of the information notification mail included in the matching opening notification is acquired, Of the application time zones associated with the user ID “ID_B” in the total information storage unit 220, If the reception time of the opening notification is included, if the reception time is not included, the unsent notification information including the user ID “ID_B” is returned to the transmission means 200, and the reception time is included. The unsealing flag stored in association with the message number in the history information storage unit 230 is updated to “1”, and the total information storage unit 220 associates with the applicable time zone and the destination user ID “ID_B”. The number of unsealed mails stored is increased by 1 (step S340), and unsealed notification reception information including the user ID “ID_B” is returned to the transmission means 200. When receiving the opening notification non-reception information including the user ID “ID_B” from the opening notification receiving unit 210, the transmission unit 200 determines that the opening notification has not been received (step S330: No), and proceeds to step S350. When the receipt notification reception information including the user ID “ID_B” is received from the receipt notification reception unit 210, the process proceeds to step S350.

  In step S300, when it is determined that the securities transaction information or the like to be notified to the user B is not received (step S300: No), the transmission unit 200 aggregates the information in association with the destination user ID “ID_B”. The application time zone including the current time is detected from the application time zones stored in the information storage unit 220, and is stored in the total information storage unit 220 in association with the application time zone and the destination user ID “ID_B”. Get the number of sent messages and the number of opened mails. Then, it is determined whether the number of unopened mails obtained by subtracting the number of opened mails from the number of transmitted mails is greater than 0 (step S305). If the number of unopened mails is greater than 0, the process proceeds to step S330, and the number of unopened mails If is less than or equal to 0, the process proceeds to step S350.

  In step S350, the transmission unit 200 refers to the application time zone and the current time stored in the total information storage unit 220 in association with the destination user ID “ID_B”, and determines whether or not the next application time zone has been reached. to decide. In the example shown in FIG. 9, when the current time is 18:00, the transmission means 200 transmits the application time zone “10: 0 to 17:59” to the next application time zone “18:00 to 23”. : 59 ”. If the transmission means 200 determines that the next applicable time zone is not reached (step S350: No), the process returns to step S300. If the transmission unit 200 determines that the next applicable time zone has come (step S350: Yes), the transmission unit 200 proceeds to step S400.

  In step S400, the transmission unit 200 determines whether or not the destination address corresponding to the current application time zone is the main mail address. For example, the transmission unit 200 sets the next application time zone “18: 0 to 23:59” recognized in step S350, that is, the current application time zone “18: 0 to 23:59” and the destination user ID “ID_B”. Information indicating the address classification stored in the total information storage unit 220 in association with each other is acquired, and it is determined whether the acquired address classification is information indicating “main”. If the address classification is information indicating “primary”, it is determined that the destination address corresponding to the current application time zone is the main mail address, and the process proceeds to step S410. The address classification is information indicating “sub”. In this case, it is determined that the destination address corresponding to the current application time zone is a secondary mail address, and the process proceeds to step S420.

In step S410, the transmission unit 200 retransmits the unopened e-mail in the previous application time zone to the destination address corresponding to the current application time zone. For example, the date of March 1, 2006 including the current time March 1, 2006 18:00 including the date in the applicable time zone stored in the total information storage unit 220 in association with the destination user ID “ID_B”. The application time zone “10: 0 to 17:59” on March 1, 2006, which is the application time zone immediately before the application time zone “18: 0 to 23:59”, is detected, and the destination user ID “ID_B”, The first to fourth header information and body information stored in the history information storage unit 230 in association with the opening flag “0” and the initial transmission flag “1” are acquired, and the acquired first to fourth header information is acquired. E-mail including the body information corresponding to those included in the applicable time zone “10: 0 to 17:59” of March 1, 2006 detected as the transmission time as the third header information is Applicable time zone “18 00 to 23: 59 "and may be re-transmitted to the terminal device of the destination address" b002@yyy.com "in association with the destination user ID" ID_B "is stored in the summary information storage unit 220. Thereby, unopened e-mail can be retransmitted to the user B among the first transmission mails in the previous application time zone. In the example of FIG. 10 and FIG. 13, an e-mail including the text information “BBBBBBB (with attached file)” of the message number “002” and the message number “005” numbered to identify the e-mail and the sender Address “a001@sss.com”, subject “Re: S-BBB”, transmission time “March 1, 2006 18:00”, destination address “b002@yyy.com”, and destination user ID “ID_B” The first e-mail included in the header information and the e-mail including the body information “CCCCCC” of the message number “003” and numbered to identify the e-mail and the sender address “a001” @ Sss.com ", subject" Re: S-CCC "and transmission time" March 1, 2006 18:00 " Retransmitting the second electronic mail including the address "b002@yyy.com" and the destination user ID "ID_B" header information.
Subsequently, the transmission unit 200 stores the transmission history of the retransmitted e-mail in the history information storage unit 230, and associates it with the message number “005”, for example, the destination user ID “ID_B”, the sender address “a001 @ sss”. .com ", subject" Re: S-BBB ", transmission time" March 1, 2006 18:00 ", destination address" b002@yyy.com ", body information" BBBBBBB (with attached file) ", opening flag “0” and the initial transmission flag “0” are stored in the history information storage unit 230, and associated with the message number “006”, the destination user ID “ID_B”, the sender address “a001@sss.com”, and the subject “Re” : S-CCC ", transmission time" March 1, 2006 18:00 ", destination address" b002@yyy.com ", text information" CC CCC ", open state flag" 0 ", stores the initial transmission flag" 0 "in the history information storage unit 230. Next, the transmission unit 200 records the history in association with the immediately preceding application time zone “10: 0 to 17:59” and the destination user ID “ID_B” in the current application time zone “18: 0 to 23:59”. The number of transmissions, the number of opened mails, and the number of notification mails stored in the information storage unit 220 are reset to the transmission number “0”, the number of opened mails “0”, and the presence information “None”. Terminate the process.

  On the other hand, in step S420, the transmission means 200 creates a number notification email containing the number of emails sent and the number of opened emails sent in the previous application time zone, and sends a destination corresponding to the current application time zone. Sent to the terminal device at the address. In this case, the transmission unit 200 firstly stores the destination address stored in the total information storage unit 220 in association with the current application time zone “18: 0 to 23:59” and the destination user ID “ID_B”; The number of transmissions, the number of opened mails, and the presence / absence information on the number of notification mails stored in the total information storage unit 220 in association with the application time zone immediately before the current application time zone and the destination user ID “ID_B” are acquired. The first condition in which the number of transmissions is “1” and the presence / absence information is “present” (that is, only the number notification mail is transmitted to the user B in the immediately preceding application time period), or the number of transmissions is “ It is determined whether the second condition of “0” (that is, a state in which no e-mail is transmitted to the user B in the immediately preceding application time period) is satisfied. If the first or second condition is satisfied, the transmission unit 200 does not perform the transmission process of the number notification mail and ends the process of this flowchart. When the first and second conditions are not satisfied, a message number for identifying the number notification mail is assigned, and the message number and the destination user ID are assigned to the terminal device having the corresponding destination address in the current application time zone. A number-notification mail including “ID_B” in the header information and including the number of transmissions and the number of opened mails in the body information is transmitted. Thereby, it is possible to notify the user B of the number of first-time transmission mails and the number of opened mails of the first transmission mails in the previous application time period. Note that the text information of the number notification mail may include information indicating the application time zone immediately before the current application time zone. Next, the transmission unit 200 increases the number of transmissions by 1 for the number of transmissions stored in the total information storage unit 220 in association with the destination user ID “ID_B” and the current application time zone, and the presence / absence information of the number notification mail. At the same time, the presence / absence information of the number notification mail is updated to information indicating “present”. Then, the transmission means 200 notifies the number of transmissions, the number of opened mails and the number of cases stored in the history information storage unit 220 in association with the previous application time zone and the destination user ID “ID_B” in the current application time zone. The mail presence / absence information is reset to the number of transmissions “0”, the number of opened mails “0”, and the presence / absence information “None”, and the processing of this flowchart ends.

  As described above, according to the mail server 10 of FIG. 8, when the user B uses a plurality of notification destination e-mail addresses in accordance with the time zone, it is transmitted to the first terminal device in the first application time zone. The first application is made by notifying the second terminal device of the secondary mail address when the use address of the second application time zone is the secondary mail address when the number of e-mails to be sent and the number of opened mails are the secondary mail address. The number of transmissions sent to the first terminal device during the time period and the number of opened mails can be notified to the user B through the second terminal, and the user B is not opened due to the difference between the number of transmissions and the number of opened mails. It is possible to recognize the presence / absence of a mail, and a second application in which an unopened electronic mail is transmitted to the first terminal device during the first application time period, following the first application time period. Time zone By using address retransmits the third terminal device of the main e-mail address when the main e-mail address, it is possible to send e-mail of the unopened user B. For example, a configuration may be adopted in which a notification mail with a small amount of information is transmitted to the mobile phone 42 and an unopened mail with a large amount of information is retransmitted to the personal computers 22 and 32.

  In step S420, the transmission unit 200 records the header information of the unopened mail at the end of the applicable time period among the e-mails transmitted by the transmission unit 200 to the terminal of the user B in the immediately previous application time period. The header information acquired from the storage unit 230 and the acquired header information may be added to the notification mail and transmitted.

  Further, in step S420, the transmission means 200 is transmitted in the previous application time period instead of the number notification mail including the number of e-mails transmitted and the number of opened mails transmitted in the previous application time period. A configuration may be adopted in which a number notification email including the number of unopened emails, which is obtained by subtracting the number of emails sent from the number of emails sent, is transmitted to a terminal device having a destination address corresponding to the current application time zone. In this way, the number of unopened emails, which is the difference between the number of emails sent to the first terminal device in the first application time zone and the number of opened emails among them, is the second application time zone. By notifying the terminal device 2, it is possible to notify the user B through the second terminal device whether there is an unopened electronic mail in the first terminal device. As an example, the text information of the number notification mail may be set as “number of transmissions in time zone 10: 00 to 17:59: 3 (of which 2 are unopened mails)”. The process of the flowchart shown in FIG. 12 may be repeatedly executed so that the user B can set the service providing period for providing the notification service from the terminal. For example, the user B can set the service providing period from the terminal in units of one month. You may do it.
