Description

  The present invention relates to a technique for preventing the mail addresses of other recipients from being leaked between recipients when a large number of email addresses are designated as transmission destinations when an electronic mail is transmitted.

  In a general mail system, “To”, “Cc”, and “Bcc” can be designated as mail destinations. “To” is used as “destination” when the mail wants to convey a message to the recipient of the specified address. “CC” (abbreviation of Carbon Copy) is not a mail for the recipient of the address, but is used when sending a reference to the fact that a mail with a specific content is transmitted to a supervisor or the like. “Bcc” (Blind Carbon Copy) is used when the address is not known to other recipients.

  By properly using “To”, “Cc”, and “Bcc”, it is possible to prevent other recipients from recognizing the email addresses of other recipients more than necessary, and to prevent leakage of personal information. However, it is difficult to ensure that these users are properly used and to prevent erroneous transmission.

  In Patent Document 1, when a plurality of mail addresses are specified in the mail header, the mail is copied by the number of mail addresses, and the addresses in the “To header” of each copied mail are set as individual addresses. E-mail transmission technology to send after replacement is provided. As a result, the recipient of the mail cannot recognize information about recipients other than himself / herself.

  Further, in Patent Document 1, the user designates an “exception domain” in advance, and among the mail addresses specified in the mail header, the mail addresses belonging to the same “exception domain” are combined into one mail for each domain. Provides technology to send. As a result, a single e-mail is sent to addresses belonging to the same exception domain (for example, addresses belonging to the same company even if the above-mentioned e-mail is sent to addresses of a plurality of companies). Is done. That is, when there are a plurality of recipients belonging to the same exception domain, it can be confirmed that the same mail is received from each other.

JP 2004-207785 A

  However, in the technique described in Patent Document 1, even if the content of the email address of the domain to which the sender of the email belongs (for example, the address of an employee of the same company as the sender) is confirmed, the email is sent to any of the suppliers. Is unknown. Also, even if you want to send to the same domain with a single email, for example, if it is a business partner, you need to respecify the exception domain each time the business partner is changed. .

The present invention determines whether or not mails should be divided for each group of destinations according to the destination of the mail for the created mail. When the mail system sends a mail as a single mail or as a divided mail according to the instructions of the sender, and sends the mail as a divided mail. The purpose of this is to set the designated destination email address as the destination for emails sent to any group .

The present invention is a mail system in which a client device that transmits / receives mail and a mail server that performs control related to mail transmission / reception can be connected via a network. The mail system comprising a designated destination storage means for storing designated destination information that is a destination to which the mail should be sent so that the destination of the other mail can be recognized, which is created in the client device A setting unit for setting a plurality of destinations for the received mail, a mail transmission request unit for requesting transmission of a mail whose destination is set by the setting unit, a mail transmission request from the client device, Mail information registration means for registering the mail in the mail information storage means, and the mail registered in the mail information storage means. The transmission destination, the designated transmission destination determining means for determining whether a destination for each said transmission destination of the designated transmission destination information stored in the specified destination storage means, according to the transmission destination of the mail The mail division determination means for determining whether the mail should be divided into mails to be transmitted for each destination group, and when the mail division determination means determines that the mail should be divided, A notification means for notifying the client device that a plurality of mails are to be transmitted, a split instruction receiving means for receiving an instruction on whether or not to split as a response to the notification by the notification means, and a plurality of split instruction receiving means When receiving an instruction to send the mail separately, it is not the designated destination to the destination user determined as the designated destination by the designated destination judging means. To permit recognition that it has sent the email to the destination, the designated destination of transmission destination has been set, respectively, and mail creating means for creating a mail for each group of destination not the designated destination, the divided When the instruction received by the instruction receiving unit is instructed not to be divided, it is transmitted using the mail registered in the mail information storage unit, and when the division instruction receiving unit instructs to divide into a plurality of mails Transmitting means for transmitting using a plurality of mails created by the mail creating means .

According to the present invention, for example, a mail sender can divide an unconscious group simply by designating and transmitting a plurality of mail addresses as mail destinations without being conscious of the group to be transmitted separately. The mail system will notify you so that you can decide whether to send separately or not. Furthermore, the mail address of the designated transmission destination becomes the transmission destination of the mail transmitted to another group, so that it becomes possible to recognize all the transmission destinations to which the mail has been transmitted .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, the first embodiment will be described.

  FIG. 1 is a diagram illustrating an example of a system configuration according to an embodiment of the present invention.

  In this mail system, at least one client apparatus 102 and a mail server 101 are connected via a network 103 (LAN / WAN), and it is possible to send and receive electronic mail (hereinafter also simply referred to as mail). Yes. Although FIG. 1 shows a case where three client devices 102a to 102c are provided as an example, any number of client devices 102a to 102c may be provided.

  When a mail sender transmits a mail from any one of the client devices (here, the client device 102 a), the mail is first received by the mail server 101 via the network 103.

  In the mail server 101, the mail server 101 is classified by the destination information attached to the header of the received mail, and is stored in the mailbox for each destination.

  The mail recipient instructs reception of mail addressed to himself / herself in one of the client devices (here, the client device 102c). Then, in the mail server 101, mail addressed to this recipient is read from one of the mailboxes in the mail server 101 and transmitted to the client apparatus 102c. As a result, the recipient of the mail can confirm the electronic mail addressed to himself / herself in the client apparatus 102c.

  Further, there may be a plurality of mail servers 101, and mail may be transmitted and received between the client apparatuses 102a and 102c via a plurality of mail servers.

  FIG. 2 is a block diagram showing an example of a hardware configuration of the mail server and client device according to the embodiment of the present invention.

  As shown in FIG. 2, the mail server 101 and the client device 102 are connected via a system bus 204 to a CPU (Central Processing Unit) 201, a RAM (Random Access Memory) 203, a ROM (Read Only Memory) 202, an input controller 205, A configuration is adopted in which a video controller 206, a memory controller 207, a communication I / F controller 208, and the like are connected.

  The CPU 201 comprehensively controls each device and controller connected to the system bus 204.

  Further, the ROM 202 or the external memory 211 will be described later, which is necessary for realizing the functions executed by each server or each PC, such as BIOS (Basic Input / Output System) and OS (Operating System) which are control programs of the CPU 201. Various programs are stored. Further, information necessary for carrying out the present invention is stored. The external memory may be a database.

  The RAM 203 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program or the like necessary for executing the processing from the ROM 202 or the external memory 211 to the RAM 203 and executing the loaded program.

  The input controller 205 controls input from a keyboard (KB) 209 or a pointing device such as a mouse (not shown).

  The video controller 206 controls display on a display device such as the display 210. The display device may be a display device such as a liquid crystal display. These are used by the administrator as needed.

  The memory controller 207 is an external storage device (hard disk (HD)), flexible disk (FD), or PCMCIA (Personal Computer) that stores a boot program, various applications, font data, user files, editing files, various data, and the like. Controls access to an external memory 211 such as a Compact Flash (registered trademark) memory connected to a Memory Card International Association (Card Memory) card slot via an adapter.

  The communication I / F controller 208 connects and communicates with an external device via the network 103, and executes communication control processing in the network. For example, communication using TCP / IP (Transmission Control Protocol / Internet Protocol) is possible.

  The CPU 201 can display on the display 210 by executing an outline font rasterization process on a display information area in the RAM 203, for example. Further, the CPU 201 enables a user instruction using a mouse cursor (not shown) on the display 210.

  Various programs to be described later for realizing the present invention are recorded in the external memory 211 and executed by the CPU 201 by being loaded into the RAM 203 as necessary. Furthermore, definition files and various information tables used when the above program is executed are also stored in the external memory 211, and a detailed description thereof will be described later.

  FIG. 3 is a block diagram showing an example of a software configuration in the mail server and client device according to the embodiment of the present invention.

  The mail server 101 includes a transmission destination reception unit 302, a transmission content reception unit 303, a classification unit 304, a mail creation unit 305, a designated domain acquisition unit 306, a replaceability determination unit 307, a character string generation unit 308, a replacement unit 309, and a transmission unit. 310, a designated domain storage unit 311, an address information storage unit 312, and a replacement rule storage unit 313.

  The transmission destination reception unit 302 receives a mail address of a mail transmission destination. The transmission content reception unit 303 receives the transmission content of mail.

  The classification unit 304 classifies the destination mail address into a group. In the embodiment of the present invention, the mail address is classified according to the domain. In addition, when a plurality of domains are stored in a designated domain storage unit 311 described later, these domains may be combined into one group.

  The mail creation unit 305 duplicates the transmission content of the mail received by the transmission content reception unit 303 for each group, and sets a mail address included in the group as a transmission destination. In addition, a copy for transmission to the designated domain may not be created, and the designated domain may be added as a transmission destination to a copy destination for transmission to a group other than the designated domain.

  The designated domain acquisition unit 306 acquires the above-described designated domain. Further, when domains are set in a designated domain storage unit 311 described later, these (one or more) domains are acquired as designated domains. Further, the domain at the mail address of the mail transmission source may be acquired as the designated domain. In the present invention, mail recipients included in the same group can recognize that they have received the same mail, but cannot recognize mail recipients belonging to other groups. However, a mail address having a domain set by the designated domain can identify recipients of other groups in the received mail.

  Based on a replacement rule stored in a replacement rule storage unit 313, which will be described later, the replaceability determination unit 307 includes a character string to be replaced in the mail body and the domain in the mail address set as the mail destination is It is determined whether or not it is set as the replacement target domain.

  The character string generation unit 308 generates an insertion character string for replacement based on the post-replacement pattern specified in the replacement rule, a mail address stored in the address information storage unit 312 to be described later, and information attached to the mail address. .

  If the replacement unit 309 determines that the replacement is possible, the replacement unit 309 replaces the insertion target character string generated by the character string generation unit 308 with the replacement target character string in the mail body. The processing of 307 to 309 is performed for each mail corresponding to each group created by the mail creation unit 305.

  The transmission unit 310 transmits the email created by the email creation unit 305.

  In the received mail, the designated domain storage unit 311 stores the domain of the mail address that can recognize the recipients of other groups as the designated domain, as described above.

  The stored address information storage unit 312 stores the mail address and the attached information of the mail address in association with each other as address information.

  The replacement rule storage unit 313 stores the e-mail text based on the e-mail address set as the e-mail address and the e-mail address set as the e-mail transmission destination and the e-mail address set as the e-mail transmission destination. Conditions such as a replacement pattern for replacing the designated character string and a replacement target domain indicating a domain of a mail address to which the replacement of the character string by the replacement pattern is applied are stored as replacement rules.

  Note that 302 to 309 and the storage units 311 to 313 constituting the mail server 101 described above may be configured on the client device 102 side. In that case, after the mail to be transmitted is created in the client apparatus 102, the transmission request unit 301 may request the mail server 101 to transmit the created mail.

  In addition, as described above, not only when all of 302 to 309 and 311 to 313 are in either the mail server 101 or the client device 102, a part is the mail server 101 and the other portion is the client device 102. The mail server 101 and the client device 102 may operate with emphasis.

  FIG. 4 is a diagram showing an example of the data structure of the address book according to the embodiment of the present invention. The address book may be centrally managed in the mail server 101 as an email address and associated information of an organization (company, group company, etc.) of a member belonging to the company. Further, it is centrally managed by a directory service or the like operated on another directory server that manages information on the mail address and environment of the user who uses the network, and may be referred to from the mail server 101 or the client device 102. Furthermore, for example, a database (individual personal information) is stored in the client device 102 used by the user or the mail server 101 that can be referred to by the user, such as a mail address of a business partner frequently used by a user and accompanying information. Address book) may be registered. In either case, the address book according to the embodiment of the present invention is a mail address and accompanying information included in the address book.

  In FIG. 4, the address book is composed of a mail address 401, a surname 402 and a first name 403 that are the first and last names of the user corresponding to the mail address stored in the mail address 401, and an organization name 404 such as a company to which the user belongs. ing. Although FIG. 4 shows one table, it may be composed of a plurality of address books. At that time, even if the names 401 to 404 are different as item names in different address books, they may be displayed in association with each other and used for processing of the mail system. In addition, when the same e-mail address exists in both the personal address book and the centrally managed address book, for example, the accompanying information on the personal address may be used preferentially. .

  FIG. 5 is a diagram showing an example of the data configuration of the table of the designated domain according to the embodiment of the present invention. In the example of email transmission to be described later, even if it is originally one email, by sending the email in units of groups that may be known to each other “who is sending the email”, Make sure that other groups do not know the recipients in other groups.

  However, if there are other recipients for the mail addresses belonging to the domain stored in the designated domain table shown in FIG. 5, the email is transmitted so that those other recipients can be identified. The specified domain table shown in FIG. The remark 502 is for making it easy for the administrator and user of the mail system to understand the explanation regarding the domain 501 and may not actually be present.

  The designated domain table may be a table that is personally managed by the user, or a table that is centrally managed by an administrator of the mail system. When both are present, for example, a personally managed table may be used preferentially.

  FIG. 6 is a diagram illustrating an image of domain-specific transmission according to the embodiment of the present invention. As indicated by reference numeral 601 in FIG. 6, six mail addresses are designated as transmission destinations together with To and Cc. Here, every three groups (“aaa.co.jp” and “aaa-sys.co.jp” group, “bbb.co.jp” group, “ccc.co.jp” group) according to the domain) The mail (text etc.) is copied to the mail address, and the mail address belonging to each group is set as the transmission destination.

  FIG. 6 shows an image in which mail is transmitted to the transmission destinations of the three groups corresponding to 602, 603, and 604 when the transmission destination is designated as 601.

  Both “aaa.co.jp” and “aaa-sys.co.jp” are grouped as designated domains in FIG. 5, and information that is a recipient is known to each other. It is because it is good. However, regardless of the setting of the designated domain, mails are transmitted separately, and information that is a recipient may be separately described in the mail (detailed in FIG. 12). By sending an email as shown in FIG. 6, it can be seen that email recipients belonging to the same group are receiving emails, but recipients of email addresses belonging to other groups are emails. It is possible to send an email so that the user does not know that the message is received.

  FIG. 7 is a diagram for explaining an image of domain-specific transmission according to the embodiment of the present invention. It is the same as the explanation of FIG. 6 that it is divided into three groups, and “aaa.co.jp” and “aaa-sys.co.jp” are set as designated domains, and thus become one group. .

  However, the mail corresponding to the group corresponding to the designated domain (here, the group corresponding to “aaa.co.jp” and “aaa-sys.co.jp”) is not duplicated, and the designated domain is not copied. Duplicates other than are created. The mail address belonging to the specified domain is set together with the mail address of the group as a destination of the mail copied for the group other than the specified domain. That is, the mail address belonging to the designated domain is set as the transmission destination of all mails in the group other than the designated domain.

  In FIG. 7, when the transmission destination is designated as 701, two groups corresponding to the mail address 702 of “BBB Inc.” and the destination 703 of “CCC Inc.” are set as the transmission destination. Shows an image of sending email. The mail address belonging to the designated domain is designated as “Cc”, but it is not necessarily “Cc” and may be “To”.

  By sending a mail as shown in FIG. 7, there is an effect that a recipient of a mail address belonging to the designated domain can recognize all other recipients who have received the sent mail.

  Further, in FIG. 7, an email including only the designated domain (a group of “aaa.co.jp” and “aaa-sys.co.jp”) is not transmitted, but an email for only the designated domain is transmitted. Also good.

  FIG. 8 is a diagram showing an example of the data configuration of the character string replacement rule according to the embodiment of the present invention. It is an example of a data configuration for setting a rule for replacing a word such as “everyone” that indicates everyone who is a destination of a mail with a specified pattern in the body of the mail.

  The character string replacement rule data includes a replacement target character string 801, a domain 802, a replacement range 803, and a post-replacement pattern 804 as replacement conditions.

  In the replacement target character string 801, a character string to be replaced is specified in the text of the mail. In FIG. 8, as an example, the setting is made so that the replacement is performed when “relevant positions” or “respective positions” appear in the text. Has been.

In domain 802, it is specified in which domain the e-mail address is to be replaced. In FIG. 8, as an example, the e-mail address belongs to “other than the designated domain” and the e-mail address belongs to “designated domain”. Are set to apply different rules. The domain 802 may be able to specify a specific domain “bbb.co.jp” or the like.

  In the replacement range 803, the effective range in the mail body of the character string to be replaced is specified. For example, the replacement is performed when the replacement target character string 801 is described within the third line from the top in the mail body. It is set as follows.

  In the replacement pattern 804, when replacing the replacement target character string 801, a pattern for generating a new character string using the pattern is set. An example of character string replacement using the above character string replacement rules will be described in detail with reference to FIGS.

  FIG. 9 is a diagram showing an example of an email editing screen according to the embodiment of the present invention. The edit screen 900 includes a destination setting area 901 (To setting area), a Cc setting area 902, a title setting area 903, a body setting area 904, and a send button 906.

  In the destination setting area 901 (To setting area) or the Cc setting area 902, in the address book of FIG. 4, other than Mr. Sato who is the sender (“sato@aaa.co.jp” of “AAA”). 6 email addresses are set. As for the text, the edit screen 900a includes a character string “relevant parties” (905a) in the first line, and the edit screen 900b includes a character string “relevant persons” (905b) in the seventh line. Yes.

  In FIG. 9, there is only one type of send button 906, but for example, a “normal send button” (not shown) when it is not desired to send a mail for each group, a mail is sent for each group. If desired, two types of buttons, “group-specific transmission buttons” (not shown), may be prepared and selected by the sender.

  FIG. 10 is a diagram showing an example of a mail transmission confirmation screen according to the embodiment of the present invention. When the “normal transmission button” (not shown) described in FIG. 9 is selected, or when there is only one type of mail address domain included in the transmission destination (in this example, the mail address 1002 is not described) ), A normal transmission confirmation screen (1000a) is displayed on the client device 102 of the sender of this mail (in this example, “Mr. Sato”).

  The confirmation message “To”, “Cc”, title confirmation area and confirmation message “Are you sure you want to send this email?” Are displayed on the normal sending confirmation screen as specified by the sender of this email. Yes.

  When the normal send button 1004 is pressed, one mail is sent to all mail addresses designated as “To” or “Cc”. Further, when the cancel button 1005 is pressed, the mail transmission is stopped.

  In addition, when the “transmission button for each domain” (not shown) described in FIG. 9 is selected, or when there are a plurality of email address domains included in the transmission destination, the transmission confirmation for each domain (1000b) is displayed in this mail. Displayed on the client device 102 of the sender (in this example, “Mr. Sato”).

  Steps 1001 to 1005 are the same as those in the normal transmission confirmation screen (1000a) (the lower half of the screen “in the case of normal transmission”). The confirmation message is displayed as "There are multiple domains in the destination. Are you sure you want to send mail for each domain?" Specifically, the e-mail addresses are enumerated that are divided into three e-mails “To (1)” to “To (3)” shown in 1006 and transmitted (corresponding to the image in FIG. 6). And confirm. In addition, it may be easy for the sender to display the attached information of the mail address in the address book (such as the organization name 404 corresponding to the domain name).

  When the domain-specific send button 1007 is pressed in 1000b, the mail is divided into three mails “To (1)” to “To (3)” shown in 1006 and sent (corresponding to the case of the image in FIG. 6). ). The mail address included in the designated domain displays a domain-specific transmission confirmation screen as “Cc (1)” and “Cc (2)” for “To (1)” and “To (2)”, respectively. Two mails may be sent (corresponding to the image in FIG. 7).

  In the above description, the “specified domain” is a domain set in the specified domain table in FIG. 5. For example, the specified domain table in FIG. The designated domain may be designated as a designated domain. That is, mail addresses belonging to the same domain as the mail sender's mail address are automatically processed as “designated domains”.

  FIG. 11 is a diagram showing an example of a mail reception screen according to the embodiment of the present invention. For example, as shown in 601 in FIG. 6, even in the case of a mail transmission request in which six mail addresses are designated, the mail is transmitted in three groups 602 to 604. The example of the reception screen in FIG. 11 is an example in which the mail address belonging to the domain “BBB Inc.” is displayed on the client device of the received user.

  In 1100a, only two mail addresses “BBB Co., Ltd.” are designated in “To”, and there is an effect that information on other destinations (recipients) is not known. Furthermore, by dividing the mail into domains, the recipients in “BBB Co., Ltd.” (recipients whose personal information is more conveniently identified with each other) can be mutually shared by Sato of “AAA Co., Ltd.” The effect is that you can recognize that you have received an email.

  Further, the top row “relevant parties” (905a) in the text setting area 904a in FIG. 9 is replaced with “BBB Co., Ltd., Mr. Kobayashi, Mr. Suzuki” (1105a). This is because the first rule in the character string replacement rule table described in FIG. 8 is applied. That is, according to the character string replacement rule of FIG. 8, “relevant party” is set as a replacement target character string by the replacement target character string 801. Further, depending on the domain 802, for the mail address other than the designated domain (in this example, “bbb.co.jp”), the mail address registered in the address book of FIG. The name 404 is used to replace the post-replacement pattern 804 (record on the first line) with “organization name + last name +“ sama ””. On the other hand, the e-mail address for the designated domain is replaced with a post-substitution pattern 804 (record on the second line) of “last name +“ san ””.

  In the editing screen 900b of FIG. 9, 904b (text setting area) also includes “relevant parties” (905b) on the last line. However, in the rule set in the character string replacement rule in FIG. 8, the replacement range 803 is set to “within the third line from the top”. For this reason, it does not become a replacement target and is displayed as it is “related parties” (1105b).

  The above-described replacement process of the character string “relevant persons” has an effect that it is easy to confirm to whom the mail is transmitted in the text.

  FIG. 12 is a diagram showing an example of a mail reception screen according to the embodiment of the present invention. As shown in FIG. 6, when mails are divided into three groups 602 to 604, “tanaka@aaa.co.jp” belonging to the same domain (specified domain) as the mail address of Mr. Sato, who is the sender, In “yamaguchi@aaa-sys.co.jp”, it is unclear who the mail was sent to other than that group. However, for example, in the email regarding business transactions between companies, if there are multiple business partners, it is necessary to prevent personal information from leaking to each other, but within the company that is the sender Sometimes it is inconvenient if you don't know who the email is being sent to.

  Therefore, for a mail address included in the designated domain, a list of transmission destinations of the mail is described on the reception screen (1200a) as 1206. According to this description, if the email address set in the specified domain in FIG. 5 (such as a user belonging to the same organization), or if the specified domain is the email address of the same domain as the sender, In addition to the domain of the same group, there is an effect of being able to grasp who (e.g. other companies) is sending mail.

  The reception screen of 1200b is an example of mail received by a mail address belonging to the domain of “BBB Inc.”. In the mail body, a description such as 1206 is not made. Instead, the mail address of the destination belonging to the designated domain or the same domain as the sender is set to “Cc” (1202b). As a result, the destination belonging to the designated domain will receive the same mail as “Cc” for every destination domain, and in the same way as described above, no one other than the same group domain (such as other companies) ) Has the effect of being able to figure out whether an email has been sent.

  FIG. 13 is a flowchart showing an example of overall processing from a mail transmission request to completion according to the embodiment of the present invention. Each step in FIG. 13 is executed by the CPU 201 of the client apparatus 102 and the CPU 201 of the mail server 101.

  In step S <b> 1301, the client apparatus accepts an input operation such as a transmission destination address, a text, and other attached files from a user who is a mail sender. This creates a mail to be sent.

  In step S1302, the client device requests the mail server to send a mail.

  In step S1303, the mail server accepts the mail transmission requested from the client device.

  In step S1304, the mail server extracts the destination mail address from the mail transmission request received earlier.

  In step S1305, the mail server determines whether a plurality of different domains exist in the extracted mail address. However, when the setting of the designated domain in FIG. 5 is used, even if different domains are set in the designated domain, they are regarded as the same domain. If there is one domain (in the case of “NO”), the process proceeds to step S1306. When there are a plurality of domains (in the case of “YES”), the process proceeds to Step 1316. Further, as described above, although there are “normal transmission button” and “transmission button for each domain” (not shown in FIG. 9), if the “normal transmission button” is pressed by the user, the process proceeds to step S1306. “When the domain-specific transmission button is pressed, the process may proceed to step S1316.

  In step S1306, the mail server sends a normal transmission confirmation request to the client device (see 1000a in FIG. 10).

  In step S1307, the client apparatus accepts a normal transmission confirmation request from the mail server.

  In step S1308, the client device accepts a sender (user) instruction by, for example, displaying the accepted confirmation request on the display of the client device. Specifically, in 1000a of FIG. 10, a pressing operation of either the normal transmission button 1004 or the cancel button 1005 is accepted from the sender (user). That is, the instruction content “normal transmission” or “cancel” is accepted.

  In step S1309, the client apparatus determines the user instruction received in step S1308. If the instruction content is “cancel”, the mail transmission process is completed. That is, this flowchart is completed. If the instruction content is “normal transmission”, the process advances to step S1310.

  In step S1310, the client device requests the mail server to send a mail.

  In step S1311, the mail server accepts a mail transmission request from the client device.

  In step S1312, the mail server executes a mail transmission request received from the client device. Details will be described in the flowchart of FIG.

  FIG. 14 is a flowchart showing an example of detailed mail transmission processing according to the embodiment of the present invention. Each step in FIG. 14 is executed by the CPU 201 of the mail server 101.

  In step S1401, the mail server determines whether the mail transmission request is “normal transmission” or “domain-specific transmission”. In this case, since the transmission request received by the mail server in step S1311 is transmitted from step S1310 of the client device, it is determined as “normal transmission”, and the process proceeds to step S1402.

  In step S1402, the mail server transmits the mail as received in response to the received transmission request, that is, as it is, that is, as a single mail, with the mail address specified in “To”, “Cc”, or the like intact. .

  Here, in the case of “normal transmission”, the character string replacement rule is not applied to the mail body. In other words, “the parties concerned” is left as it is. This is because when the mail is transmitted as it is, it is possible to confirm to whom the mail has been transmitted by confirming the received mail address. However, the transmission destination may be described in the text by applying a character string replacement rule.

  When the transmission of the mail is completed, the flowchart of FIG. 14 in the case of “normal transmission” is completed. That is, step S1312 in FIG. 13 ends. Returning to FIG.

  In step S1313, the mail server notifies the client device that mail transmission has been completed.

  In step S <b> 1314, the client device accepts completion of mail transmission from the mail server.

  In step S1315, the client device notifies the sender (user) that mail transmission has been completed, for example, by displaying it on the display of the client device. Thus, the description of the flowchart of FIG. 13 in the case of “normal transmission” is completed.

  The description returns to step S1305 when it is determined that a plurality of domains are included in the destination mail address requested to be transmitted to the mail server (in the case of “YES”). In that case, the process proceeds to step S1316.

  In step S1316, the mail server sends a confirmation request for domain-specific transmission to the client device (see 1000b in FIG. 10).

  In step S1317, the client apparatus receives a confirmation request for transmission by domain from the mail server.

  In step S <b> 1318, the client device accepts a sender (user) instruction by displaying the accepted confirmation request on the display of the client device. Specifically, in 1000b of FIG. 10, a pressing operation of any one of the domain-specific transmission button 1007, the normal transmission button 1004, and the cancel button 1005 is accepted from the sender (user). That is, an instruction content of “transmission by domain”, “normal transmission”, or “cancel” is accepted.

  In step S1319, the client apparatus determines the user instruction received in step S1318. If the instruction content is “cancel”, the mail transmission process is completed. That is, this flowchart is completed. If the content of the instruction is “normal transmission”, the process proceeds to step S1310. If the instruction content is “transmission by domain”, the process proceeds to step S1320.

  In step S1320, the client device requests the mail server to send a mail.

  In step S1311, the mail server accepts a mail transmission request from the client device.

  In step S1312, the mail server executes a mail transmission request received from the client device. Details will be described again in the flowchart of FIG.

  In step S1401, the mail server determines whether the mail transmission request is “normal transmission” or “domain-specific transmission”. In this case, since the transmission request received by the mail server in step S1311 is transmitted from step S1320 of the client apparatus, it is determined as “transmission by domain”, and the process proceeds to step S1403.

  In step S1403, the mail server groups the mail addresses included in the received transmission request by domain. Those included in the specified domain are considered as one group.

  Steps S1404 to S1414 are loop processing for transmitting mail for each group.

  In step S1405, the mail server focuses on one group.

  In step S1406, the mail server duplicates the mail (text, attached file, etc.) of the mail received in the mail transmission request of the client device for transmission to the group of interest.

  In step S1407, the mail server determines whether there is a character string to be replaced based on the replacement target character string 801 and the replacement range 803 in FIG. If there is (“YES”), the process proceeds to step S1408. If not (“NO”), the process proceeds to step S1410.

  In step S1408, the mail server determines whether the target character string can be replaced. That is, based on each rule included in the character string replacement rule table of FIG. 8, it is determined whether or not the mail destination address is specified in the replacement condition domain 802. If the replacement is possible (in the case of “YES”), the process proceeds to step S1409. If the replacement is not possible (“NO”), the process proceeds to step S1410.

  Further, the case where the replacement is impossible is, for example, the information necessary for generating the character string defined in the replacement pattern 804 with the attached information of the mail address (organization name, surname, etc.) in FIG. There are cases where it is not listed in the address book.

  However, the replacement process described later is executed only when all of the email addresses included in the group under consideration can be replaced, or if there is one that can be replaced, it is replaced and the email address that cannot be replaced is replaced. It is possible to implement various processes to execute within the range that can be replaced. For example, even if the organization name is not known, only the last name is replaced, or when there is no additional information, a process such as adding an e-mail address and adding “sama” to the mail may be implemented. Depending on the content of the replacement process described later, whether the determination in step S1408 is replaceable (“YES”) or not replaceable (“NO”) may be implemented differently.

  In step S1409, the mail server replaces the replacement target character string 801 based on the replacement pattern 804 in FIG. 8 (see 1105a in FIG. 11, 1205a, 1205b in FIG. 12, and the like). As described in step S1408, various implementations are possible whether to perform replacement processing for all mail addresses or within a possible range, and the implementation is not particularly limited.

  In step S1410, the mail server determines whether the group under consideration corresponds to the designated domain. Specifically, it is determined whether the domain part of the mail address included in the group under consideration is set in the designated domain table of FIG. Further, as described above, the designated domain table in FIG. 5 may not be used, and “the domain to which the address of the mail sender belongs is set as the designated domain” may be used. If it is a designated domain (“YES”), the process advances to step S1411. If it is not the designated domain (“NO”), the process advances to step S1412.

  In step S1411, the mail server describes that there is another mail recipient in the mail body (see 1206 in FIG. 12).

  In step S1412, the mail server sets a mail address belonging to the group under attention as a mail transmission destination. In addition, when the group under attention is other than the designated domain, in addition to the group under attention, a mail address belonging to the group of the designated domain may be additionally set as a transmission destination (see 1202b in FIG. 12). ). In addition, when the mail address belonging to the group of the designated domain is additionally set as the destination of the mail to be sent to another group, the mail having only the group of the designated domain as the destination may not be sent.

  In step S1413, the e-mail created as described above and set as the transmission destination is transmitted.

  When the above processing is completed for all groups, the flowchart of FIG. 14 in the case of “transmission by domain” is completed. That is, step S1312 in FIG. 13 ends. The subsequent steps in FIG. 13 are the same as those already described, and will be omitted. Thus, the description of the flowchart of FIG. 13 in the case of “normal transmission” is completed.

  In the flowcharts of FIGS. 13 and 14, the mail is copied to the group of the designated domain and the other group (S1406 of FIG. 14), and the mail sent to the designated domain is also mailed to other groups in the text. Is added (S1411 in FIG. 14).

  As another method, the mail to be transmitted to the designated domain is not duplicated (S1406 in FIG. 14 is not executed, and therefore the comment addition in S1411 is not executed). By setting the mail address of the designated domain as the destination of the copied mail, the transmission method as described in FIG. 7 can be adopted.

  In this case, the designated domain may be “BCC”. As a result, it is possible to prevent other groups from recognizing who sent to the destination of the designated domain. In the designated domain, “BCC” may be used in combination with the above-described comment addition (S1411 in FIG. 14) so as to be understood from each other.

  Further, in the above description, “designated domain” is described because “e-mail recipient to send information of mail recipients belonging to other groups in a recognizable manner” is described as an example based on the domain. The designated domain is also one form of the “designated transmission destination” of the present invention. Correspondingly, the “instruction domain storage unit” is one form of the “designated transmission destination storage unit”. In other words, the “designated transmission destination” is “a transmission destination of a mail that is recognizable and transmits information of another mail recipient”.

  Next, a second embodiment will be described. The second embodiment is an example in which “group” and “designated destination” can be set in any of “mail address”, “mail address domain”, and “group” as well as the mail address domain. explain.

  FIG. 15 shows an example in which the group setting storage unit and the designated transmission destination storage unit according to the embodiment of the present invention are configured as one table.

  In “email address or domain” 1501, a designated transmission destination flag or a domain name of a mail address for defining a group is registered.

  The group ID 1502 is information for setting one or more mail addresses or domains as one group as a transmission destination of one mail (replicated).

  The designated transmission destination flag 1503 designates whether or not the corresponding group ID 1502 (the transmission destination belonging to the group) is “designated transmission destination”. When the designated transmission destination flag is “true”, the transmission destination belonging to the corresponding group ID is the designated transmission destination. If it is “false”, it is not a designated transmission destination.

  In FIG. 15, one table configuration is used, but it may be divided into two configurations. For example, when a group is created by a domain as in the first embodiment, the definition of the group ID 1502 is not necessary. In the first embodiment, the domain is registered in the designated domain storage unit 311. However, in the second embodiment, not only the domain but also a specific mail address or a plurality of transmission destinations at a time. A group mail address (broadcast mail address) for sending mail may be registered. Correspondingly (when the group ID 1502 is not defined), the designated transmission destination flag 1503 may be defined for each mail address or domain, or may be defined for a plurality of mail addresses or domains. It may be.

  FIG. 16 is a flowchart showing an example of overall processing from a mail transmission request to completion according to the second embodiment of the present invention. Each step in FIG. 16 is executed by the CPU 201 of the client apparatus 102 and the CPU 201 of the mail server 101. The flowchart in FIG. 16 is almost the same as that in FIG. 13, and thus the steps for performing the same processing are given the step numbers in FIG.

  In step S1605, the mail server determines whether the extracted mail address is classified into a plurality of different groups. Specifically, the group setting storage unit in FIG. 15 is referred to, a group corresponding to the extracted mail address is acquired, and it is determined whether the group is one or plural. If there is one group (in the case of “NO”), the process proceeds to step S1306. When there are a plurality of groups (in the case of “YES”), the process proceeds to Step 1616.

  In step S1616, the mail server sends a confirmation request for transmission by group to the client device.

  In step S1617, the client apparatus accepts a confirmation request for transmission by domain from the mail server.

  In step S <b> 1618, the client device accepts a sender (user) instruction by displaying the accepted confirmation request on the display of the client device. Specifically, a screen similar to 1000b in FIG. 10 is displayed for confirmation. The difference on the screen is that the title changes from “domain-specific transmission confirmation” to “group-specific transmission confirmation” and the domain-specific transmission button 1007 becomes “group-specific transmission button”. In addition, description of the difference in detail is omitted. A pressing operation of any one of the group-specific transmission button, the normal transmission button 1004, and the cancel button 1005 is accepted from the sender (user). That is, the instruction content of “transmission by group”, “normal transmission”, or “cancel” is accepted.

  In step S1619, the client apparatus determines the user instruction received in step S1618. If the instruction content is “cancel”, the mail transmission process is completed. That is, this flowchart is completed. If the instruction content is “normal transmission”, the process advances to step S1310. If the instruction content is “transmission by group”, the process proceeds to step S1620.

  In step S1620, the client device requests the mail server to send a mail.

  FIG. 17 is a flowchart showing an example of detailed mail transmission processing according to the embodiment of the present invention. That is, it is executed when a transmission process is requested from step S1312 of FIG. Each step in FIG. 17 is executed by the CPU 201 of the mail server 101. Since the flowchart of FIG. 17 is almost the same as that of FIG. 14, the steps for performing the same processing are assigned the step numbers of FIG. Further, when the mail transmission request is “normal transmission”, the processing is the same as that in FIG. 14, so “transmission by group” that is the transmission request from step S 1620 in FIG. 16 will be described.

  In step S1701, the mail server determines whether the mail transmission request is “normal transmission” or “group-specific transmission”. In this case, since the transmission request accepted by the mail server in step S1311 is transmitted from step S1620 of the client apparatus, it is determined as “transmission by group”, and the process proceeds to step S1703.

  In step S1703, the mail server groups the mail addresses included in the received transmission request by group. Those included in the designated transmission destination are regarded as one group. Specifically, it is classified into groups with reference to the group setting storage unit of FIG.

  Steps S1704 to S1714 are loop processing for transmitting mail for each group.

  In step S1710, the mail server determines whether the group under consideration corresponds to the designated transmission destination. Specifically, it is determined whether or not the transmission destination portion of the mail address included in the group under consideration has the designated transmission destination flag set to “true” in FIG. If it is the designated transmission destination (in the case of “YES”), the process proceeds to step S1411. If it is not the designated domain (“NO”), the process advances to step S1412.

  When the above processing is completed for all groups, the flowchart of FIG. 17 is completed. That is, step S1312 in FIG. 16 ends.
