Description

  The present invention relates to an electronic mail system that can cancel transmission of an electronic mail that has been subjected to transmission processing due to various circumstances, such as forgetting to attach an attached file to an electronic mail.

  E-mail is widely used on a daily basis. However, since e-mail can be sent easily, the sending process is performed for various reasons, such as forgetting to attach or forgetting to write the matter to be written, even though the attached file must be attached to the e-mail. In some cases, it may be desirable to cancel the transmission of an e-mail.

  In this case, in a general electronic mail system, once transmission processing is performed, the transmission processing cannot be canceled. This is because in the electronic mail system, the electronic mail is immediately sent to the outgoing mail server used by the sender after the transmission processing, and is sent from the outgoing mail server to the incoming mail server used by the receiver.

  In addition, although not a case of using a general electronic mail system, there is also a method as shown in Non-Patent Document 1, for example. In Non-Patent Document 1, when both the sender and the receiver use the same electronic mail system (Microsoft Exchange), since both are the same system, the transmitted electronic mail can be canceled. .

Recruit Holdings Co., Ltd., “Cancellation of E-mail” | web R25 ”, Internet <URL: http://r25.yahoo.co.jp/fushigi/rxr_detail/?id=20120718-00024996-r25>

  In the case of Non-Patent Document 1, the sender and the receiver must use the same electronic mail system (Microsoft Exchange). Therefore, it cannot be applied when the e-mail system used by the sender and the receiver is different.

  Accordingly, there is a demand for an electronic mail system that can cancel the electronic mail transmission process even if the sender and the receiver use different electronic mail systems.

  In view of the above problems, the present inventor has made the following invention.

  A first invention is an electronic mail system for processing an electronic mail from a sender to a receiver, the electronic mail system including a sender terminal used by the sender, a first outgoing mail server, And a second outgoing mail server, wherein the sender terminal detects a trigger operation in the sender terminal used by the sender of the electronic mail, and the trigger. When detected, a condition determination processing unit that determines whether the e-mail satisfies a predetermined condition, and a determination result in the condition determination processing unit to the first outgoing mail server via a first port number Or a mail processing unit for switching the transmission process to the second transmission mail server via a second port number and transmitting the electronic mail. The outgoing mail server transmits the electronic mail received from the sender terminal to the incoming mail server of the recipient as it is, and the second outgoing mail server receives the electronic mail from the sender terminal when the electronic mail is received. An e-mail system comprising: a mail reception processing unit for holding a mail transmission process; and a mail transmission processing unit for sending the e-mail to the reception mail server after releasing the hold of the e-mail transmission process.

  By configuring as in the present invention, it is possible to switch the outgoing mail server depending on whether or not a predetermined condition is satisfied. As a result, when sending to the first outgoing mail server, the electronic mail can be sent as it is to the incoming mail server by sending, and when sending to the second outgoing mail server, the outgoing mail server temporarily , Transmission processing can be suspended. As a result, the e-mail transmission process cannot be sent immediately, and the transmission process can be canceled.

  In the above-described invention, when the mail reception processing unit receives a request for canceling the electronic mail from the sender terminal while the electronic mail transmission process is suspended, the mail reception processing unit receives the electronic mail from the second transmission mail server. It can be configured like an e-mail system to be deleted.

  Canceling the e-mail transmission process can also be realized by the configuration of the present invention.

  In the above-described invention, the sender terminal receives a confirmation operation as to whether or not to send the electronic mail, and sends a request corresponding to the operation to the second outgoing mail server. The mail reception processing unit receives the electronic mail from the sender terminal and suspends the transmission process of the electronic mail, and after the set confirmation time has elapsed, It can be configured as an electronic mail system that displays a confirmation message for the electronic mail transmission process and prompts a confirmation operation as to whether or not to transmit the electronic mail.

  After the second outgoing mail server holds the electronic mail, the electronic mail is not sent unless the electronic mail is released. Therefore, it is preferable to prompt confirmation of whether or not to transmit by displaying a confirmation message from the second transmission mail server to the sender terminal.

  In the above-mentioned invention, the mail reception processing unit receives the transmission request for the electronic mail corresponding to the confirmation message, or does not accept the cancellation request for the electronic mail corresponding to the confirmation message within a predetermined time. Can be configured as an e-mail system that causes the received e-mail to be sent from the e-mail transmission processing unit to the received e-mail server.

  In addition to accepting an e-mail transmission request from the sender terminal, it is preferable that the e-mail be transmitted even when a cancel request is not accepted within a predetermined time. Thus, even when the sender terminal is not turned on, the network is disconnected, or the sender is absent, transmission can be performed without any problem.

  In the above invention, the second outgoing mail server has a confirmation time information storage unit for storing a confirmation time until a confirmation message for the received electronic mail is displayed on the sender terminal, and a confirmation from the sender terminal. It can be configured like an e-mail system having a confirmation time setting processing unit that accepts the time setting and stores it in the confirmation time information storage unit.

  As in the present invention, the confirmation time may be set in advance.

  A second invention is an electronic mail system for processing an electronic mail from a sender to a receiver, and the electronic mail system performs an operation that becomes a trigger at a sender terminal used by the sender of the electronic mail. A trigger detection processing unit to detect, a condition determination processing unit for determining whether the e-mail satisfies a predetermined condition when the trigger is detected, and a transmission mail server are switched based on a determination result in the condition determination processing unit A mail processing unit that transmits the e-mail, and the mail processing unit accepts from the sender terminal if a predetermined condition is not satisfied as a result of the determination in the condition determination processing unit. The e-mail is sent via a first port number to a first outgoing mail server that sends the e-mail to the recipient's incoming mail server as it is. As a result of the determination in the condition determination processing unit, when an e-mail is received from the sender terminal, the transmission process to the received mail server is suspended and the received mail is released after the e-mail is accepted. In the electronic mail system, the electronic mail is transmitted to a second transmission mail server to be sent to the server via a second port number.

  The same technical effects as described above can be obtained by configuring the present invention.

  The above-described invention can also be realized by executing the program of the present invention on a computer. That is, a trigger detection processing unit for detecting a trigger operation in the e-mail software for a computer in which e-mail software is installed, and a condition determination for determining whether the e-mail satisfies a predetermined condition when the trigger is detected A program that switches a transmission mail server based on a determination result in the processing unit and the condition determination processing unit to function as a mail processing unit that transmits the electronic mail, wherein the mail processing unit includes the condition determination processing unit If the predetermined condition is not satisfied as a result of the determination in, the electronic mail received from the sender terminal is sent to the first outgoing mail server that sends it directly to the incoming mail server of the recipient, and the electronic mail is sent to the first port number. As a result of the determination by the condition determination processing unit. In the case of satisfying, when an e-mail is received from the sender terminal, the e-mail is sent to the second outgoing mail server which is sent to the incoming mail server after the transmission processing to the incoming mail server is suspended and released. It can be configured like a program that transmits via a port number of 2.

  With the configuration of the present invention, it is possible to cancel the e-mail transmission process even if the sender and receiver use different e-mail systems.

It is a conceptual diagram which shows typically an example of the system configuration | structure of the electronic mail system of this invention. It is a conceptual diagram which shows typically an example of the hardware constitutions of the computer used with the electronic mail system of this invention. It is a flowchart which shows typically an example of the process of the electronic mail system of this invention. It is a figure which shows typically an example of the correspondence of the port number utilized when the port number used normally and the conditions are satisfied. It is a figure which shows an example of a confirmation time information storage part typically. It is a figure which shows an example of a confirmation message typically.

  An example of the system configuration of the electronic mail system 1 of the present invention is schematically shown in the conceptual diagram of FIG. The electronic mail system 1 of the present invention includes a sender terminal 2 used by an electronic mail sender, a receiver terminal 6 used by an electronic mail recipient, a first outgoing mail server 4, and a second A transmission mail server 3 and a reception mail server 5 are provided.

  The sender terminal 2, the receiver terminal 6, and each mail server are realized by a computer. FIG. 2 schematically shows an example of the hardware configuration of the computer. The computer includes an arithmetic device 70 such as a CPU for executing program arithmetic processing, a storage device 71 such as a RAM and a hard disk for storing information, a display device 72 such as a display, a keyboard and a pointing device (such as a mouse and a numeric keypad). ), And a communication device 74 that transmits and receives the processing result of the arithmetic device 70 and information stored in the storage device 71 via a network such as the Internet or a LAN.

  Although FIG. 1 shows the case where the first outgoing mail server 4, the second outgoing mail server 3, and the incoming mail server 5 are realized by a single computer, the functions are distributed to a plurality of computers. And may be realized.

  Each means in the present invention is only logically distinguished in function, and may be physically or virtually the same area.

  The first outgoing mail server 4 is a outgoing mail server (SMTP server) that is normally used by the sender of the email, and does not satisfy a predetermined condition, such as when the email does not contain a predetermined word. The e-mail server to use.

  The second outgoing mail server 3 is a outgoing mail server (SMTP server) sent by the sender of the electronic mail. In the processing of the present invention, the second outgoing mail server 3 has a predetermined condition such as a predetermined word included in the electronic mail. This is an e-mail server used when satisfying.

  The incoming mail server 5 is an electronic mail server (POP server, IMAP server) used by the recipient of the electronic mail. By acquiring the e-mail received by the received mail server 5 at the receiver terminal 6, the receiver can view the e-mail sent from the sender.

  The sender terminal 2 includes a trigger detection processing unit 30, a condition determination processing unit 31, a mail processing unit 32, and a confirmation operation reception processing unit 33.

  The trigger detection processing unit 30 detects whether an operation that serves as a trigger for starting the processing of the present invention has been performed. As an operation that becomes a trigger, for example, there is an “e-mail transmission process” in e-mail software in the sender terminal 2.

  When the trigger detection processing unit 30 detects a trigger operation, the condition determination processing unit 31 determines whether a predetermined condition is satisfied, such as whether a preset word is included in the body of the e-mail or the like. . For example, there are “attachment”, “attach”, “attached”, “attachment”, etc. as conditions, but any word, “file”, “confidential”, “secret”, etc. can be set. good.

  If the condition setting processing unit determines that the preset condition is not satisfied (for example, if it is determined that a preset word is not included), the mail processing unit 32 sends the e-mail. The message is sent to the first outgoing mail server 4 via a normally set port number (first port number). On the other hand, if the condition setting processing unit determines that a preset condition is satisfied (for example, if it is determined that a preset word is included), the e-mail is sent to the second outgoing mail server. 3 is sent via a port number (second port number) set for use in the processing of the present invention.

  For example, it is assumed that the word “attached” is set as a condition, the port number when the condition is not satisfied is “TCP25port”, and the port number when the condition is satisfied is “TCP587port”. In this case, if the word “attachment” is not included in the body of the electronic mail, the mail processing unit 32 sends the electronic mail to the first transmission mail server 4 via “TCP25port”. On the other hand, if the word “attachment” is included in the body of the electronic mail, the mail processing unit 32 sends the electronic mail to the second outgoing mail server 3 via “TCP587port”.

  In recent years, “TCP587port” is sometimes used as a port number for sending a commonly used electronic mail as a countermeasure against spam mail. In such a case, when sending an electronic mail to the second outgoing mail server 3, for example, “TCP465port” may be used.

  FIG. 4 schematically shows an example of a correspondence table between port numbers used in normal cases (when conditions are not satisfied) and port numbers used when conditions are satisfied.

  Whether the confirmation operation reception processing unit 33 transmits an e-mail from a second transmission mail server 3 to be described later, and displays a confirmation message for transmitting or canceling the e-mail. The cancel operation is accepted and a transmission request or cancellation request is sent to the second transmission mail server 3.

  The second transmission mail server 3 includes a confirmation time setting processing unit 20, a confirmation time information storage unit 21, a mail reception processing unit 22, a time measurement processing unit 23, and a mail transmission processing unit 24.

  The confirmation time setting processing unit 20 accepts, from the sender terminal 2, a time setting for canceling the electronic mail transmission process for the electronic mail transmitted via the second transmission mail server 3. In this case, information for identifying the sender (for example, the sender's e-mail address) and confirmation time information are received from the sender terminal 2 and stored in the confirmation time information storage unit 21 described later.

  The confirmation time set here holds the e-mail and displays a confirmation message until the e-mail reception processing unit 22 (to be described later) receives the e-mail from the sender terminal 2 and sends it from the e-mail transmission processing unit 24. Indicates the time until. Then, after the confirmation time has elapsed, the second outgoing mail server 3 displays a confirmation message on the sender terminal 2, so that the confirmation message is displayed on the sender terminal 2 according to the confirmation time. It becomes. Therefore, if you remember that you forgot to attach an attachment to the email during the confirmation time, you can cancel the email transmission process, and a confirmation message will be displayed. You can also review the email sending process.

  The confirmation time information storage unit 21 stores the sender identification information and the confirmation time in association with each other. FIG. 5 schematically shows an example of the confirmation time information storage unit 21. The confirmation time set here is preferably set, for example, between about 3 seconds and about 3 minutes, but is not limited thereto.

  The mail reception processing unit 22 receives an electronic mail from the sender terminal 2 and specifies the sender identification information by referring to the electronic mail address in the electronic mail. Then, by referring to the confirmation time information storage unit 21 based on the sender identification information, the confirmation time of the electronic mail is specified, and the electronic mail is transmitted until the confirmation time has passed and the request for the confirmation message is received. Defer processing. The confirmation time is counted by a timing processing unit 23 described later.

  After elapse of the confirmation time, the mail reception processing unit 22 displays a confirmation message as shown in FIG. 6 on the sender terminal 2 of the sender of the electronic mail, and issues an electronic mail transmission cancellation request for a predetermined time. If the request is not received within, or if the transmission request is received within a predetermined time, the request for sending the electronic mail is passed to the mail transmission processing unit 24. On the other hand, when receiving a cancel request in the confirmation message, the mail reception processing unit 22 deletes the electronic mail and cancels the transmission process.

  The time measurement processing unit 23 measures the time from when the e-mail is received from the sender terminal 2.

  When the e-mail transmission processing unit 24 receives an e-mail transmission request from the e-mail reception processing unit 22, the e-mail transmission unit 24 transmits the e-mail to the reception mail server 5 that is a reception destination.

  Next, an example of the processing process of the present invention will be described with reference to the flowchart of FIG.

  First, the user who is the sender of the e-mail accesses the second outgoing mail server 3 by performing a predetermined operation on the sender terminal 2 and performs a confirmation time setting process. Specifically, a confirmation time and sender identification information, for example, an e-mail address of the sender, are input at the sender terminal 2 and sent to the second outgoing mail server 3. When the confirmation time setting processing unit 20 of the second outgoing mail server 3 receives the information, the confirmation time setting processing unit 20 stores the information in the confirmation time information storage unit 21.

  Next, a case where the sender sends an e-mail will be described. In this case, a user who is an e-mail sender activates e-mail software and creates an e-mail. Then, a process of sending an e-mail, for example, a “send” button is pressed. Then, the trigger detection processing unit 30 detects a trigger operation, for example, pressing of the “Send” button (S100), and the condition determination processing unit 31 starts a process of reading the e-mail text (S110). In other words, it is determined whether to execute a process capable of canceling the e-mail transmission process (S120).

  The condition determination processing unit 31 performs the above-described processing when a condition is set as to whether a predetermined word is included in the e-mail body, but other conditions may be set as the condition. it can. For example, in addition to the email text, the subject of the email may be included as a judgment target condition, the email address of the recipient is a predetermined email address, or the email file size is a predetermined size. It may be included as a condition if it is larger than the size.

  When the condition setting processing unit determines that the condition is not satisfied, for example, when it is determined that a predetermined word is not included in the e-mail body, the mail processing unit 32 is set in advance by e-mail software. The electronic mail is transmitted to the first outgoing mail server 4 via the first port number (for example, “TCP25port”) (S130). The first outgoing mail server 4 receives this electronic mail (S140) and sends the electronic mail to the recipient's incoming mail server 5 (S150). S130 to S150 are normal e-mail transmission processes.

  On the other hand, if it is determined in the determination process of S120 that the condition setting processing unit satisfies the condition, for example, if it is determined that a predetermined word is included in the e-mail body, the mail processing unit 32 The electronic mail software transmits the electronic mail to the second outgoing mail server 3 via the second port number (for example, “TCP587port”) set for sending to the second outgoing mail server 3 (S160). ). Then, the mail reception processing unit 22 of the second outgoing mail server 3 receives this electronic mail (S170).

  When the e-mail is received by the mail reception processing unit 22, the time measurement processing unit 23 starts timing. On the other hand, the mail reception processing unit 22 specifies sender identification information based on an electronic mail address or the like in the received electronic mail. Then, the cancellation information storage unit is referred to using the specified sender identification information, the confirmation time of the sender is specified, and the transmission processing of the received electronic mail is performed until the time measurement unit 23 counts the confirmation time. Hold (S180).

  When the timing processing unit 23 measures that the confirmation time has elapsed, the mail reception processing unit 22 sends a confirmation message as shown in FIG. 6 to the sender terminal 2 of the sender of the electronic mail and displays it. (S190).

  When the sender viewing this display presses the “Send” button in the confirmation message, the confirmation operation acceptance processing unit 33 accepts the operation, and the confirmation operation acceptance processing unit 33 sends the transmission request to the sender terminal 2. To the second outgoing mail server 3. When the mail reception processing unit 22 receives the transmission request (S200), the suspension of the electronic mail transmission processing is canceled, the electronic mail transmission request is passed to the mail transmission processing unit 24, and the mail transmission processing unit 24 The electronic mail is sent to the incoming mail server 5 (S210).

  If the mail reception processing unit 22 does not receive any request (transmission request, cancellation request) within a certain time after the confirmation message in S190 is displayed, the mail reception processing unit 22 Cancels the suspension of the e-mail transmission process, passes the e-mail transmission request to the e-mail transmission processing unit 24, and the e-mail transmission processing unit 24 sends the e-mail to the received mail server 5 (S210). In this case, a request to turn off the display of the confirmation message is sent after a certain period of time, and the display is deleted. Thereby, even when the sender is away from the sender terminal 2 or when the power of the sender terminal 2 is turned off, it is possible to send the temporarily suspended e-mail.

  On the other hand, the confirmation message in S190 is displayed on the sender terminal 2, and when the sender who has viewed it presses the “cancel” button in the confirmation message, the confirmation operation acceptance processing unit 33 accepts the operation and confirms it. The operation reception processing unit 33 sends a request to cancel the electronic mail from the sender terminal 2 to the second outgoing mail server 3. When the cancellation request is received by the mail reception processing unit 22 (S200), the mail reception processing unit 22 deletes the electronic mail and cancels the transmission process (S220). With this process, it becomes possible for the sender to cancel the transmission process for an electronic mail that satisfies a certain condition.

  When the e-mail sent from the first outgoing mail server 4 or the second outgoing mail server 3 is accepted by the incoming mail server 5 in S150 or S210, the recipient terminal 6 receives the electronic mail (S230). As a result, the receiver terminal 6 can receive and browse the email sent from the sender terminal 2.

  In the electronic mail system 1 of the present invention, each means in the sender terminal 2 may be configured as a so-called plug-in program that is installed and used as a function of the electronic mail software provided in the sender terminal 2.

  With the configuration according to the present invention, the e-mail transmission process can be canceled without depending on the e-mail system 1 used by the sender and the receiver, so that versatility is enhanced.
