  Here, the receiving unit 301 receives an email sent via the network 100. The transmission mode detection unit 302 is in a temporary transmission mode in which the e-mail received by the receiving unit 301 is premised on a later update, or in the re-transmission mode for updating the temporary transmission mode e-mail transmitted earlier. Detect whether or not. The update authority determining unit 303 determines whether or not the received retransmission mode e-mail is from a mail address having update authority. This determination is based on whether or not the source mail address of the received retransmission mode e-mail is an e-mail address having update authority described in the address book stored in the address book folder in the address book folder storage unit 307. It is done by judging.

  The update authority setting unit 314 sets the update authority for the mail address. The update target e-mail detection unit 304 has the same source mail address as the re-send mode e-mail having the update authority received in the in-tray folder in the in-tray folder storage unit 308, and the same subject and the same author. In the temporary transmission mode e-mail, it is detected whether or not unopened ones are stored. Further, in this detection, the creation date of the temporary transmission mode e-mail may be referred to.

  The e-mail storage / deletion processing unit 305 performs e-mail storage / deletion processing based on the processing results of the transmission mode detection unit 302, the update authority determination unit 303, and the update target e-mail detection unit 304. In other words, the re-sending mode e-mail that is the updated e-mail, the temporary sending mode e-mail before the re-sending mode e-mail is sent, and the normal sending mode e-mail are saved and updated and are no longer needed. The provisional transmission mode e-mail is deleted. The e-mail to be stored is stored in the inbox folder, and the e-mail to be deleted is stored in the deleted item tray folder in the deleted item tray folder storage unit 309. The display unit 306 displays an e-mail creation form, a transmission mode of the received e-mail, and the like.

The created electronic mail is sent to the transmission unit 313 and is transmitted to the network 100 from here. In addition, the temporary transmission mode email detection unit 311 periodically searches for unopened temporary transmission mode emails stored in the inbox folder at predetermined time intervals (set by the user).

  When the unopened temporary transmission mode e-mail is detected in the temporary transmission mode e-mail detecting unit 311, the reminder mail creating unit 312 transmits the re-sent mail to the transmission source of the unopened temporary transmission mode e-mail. A reminder email is created. This reminder mail is transmitted from the transmission unit 313 to the network 100. When this reminder mail is received by the receiving unit 301 of the user terminal, it is detected by the transmission mode detecting unit 302. Thereafter, the re-sending mode e-mail is created by the e-mail creating unit 310 and transmitted.

  In the e-mail transmission / reception system according to the embodiment of the present invention, the transmitted e-mail is updated by sending an e-mail for updating to the destination user terminal instead of the mail server. Mail doesn't stay on the mail server longer than necessary.

  Note that the reception unit 301 and the transmission unit 313 can realize their functions by, for example, the I / F 209 shown in FIG. Further, the transmission mode detection unit 302, the update authority determination unit 303, the update target mail detection unit 304, the e-mail storage / deletion processing unit 305, the temporary transmission mode e-mail detection unit 311, and the update authority setting unit 314 are illustrated in FIG. The function can be realized by the CPU 201 shown in FIG.

  The function of the display unit 306 can be realized by, for example, the display 208 shown in FIG. The functions of the address book folder storage unit 307, the inbox tray storage unit 308, and the deleted item tray folder storage unit 309 can be realized by, for example, the HDD 204 and the HD 205 shown in FIG. The functions of the e-mail creating unit 310 and the reminder e-mail creating unit 312 can be realized by the CPU 201, the keyboard 210, the mouse 211, and the like shown in FIG.

  The e-mail transmission / reception system according to the present invention is configured as described above, and even if it is an e-mail once sent to a destination, the description contents are corrected / added until the recipient opens the e-mail. It becomes possible. Also, when an e-mail that is scheduled to be updated later is sent and the e-mail is not updated for a certain period of time, the sender can be urged to do so. be able to. Further, in this e-mail transmission / reception system, the e-mail after transmission is sent to the destination user terminal without staying in the mail server for an unnecessarily long time, so that urgent communication is not hindered.

(Update authority setting processing procedure for email address)
Hereinafter, an e-mail transmission / reception processing procedure using the e-mail transmission / reception system according to the embodiment of the present invention will be described.

  First, an update authority setting process procedure for a sender email address that permits email update will be described. FIG. 4 is a flowchart showing the update authority setting processing procedure for this source mail address. The update authority setting for the sender mail address is performed by the update authority setting unit 314 (step S401). Specifically, as shown in FIG. 5, the update authority setting unit 314 creates an address book 500 in which the source mail address and the update authority are associated with each other.

  In this address book 500, for example, “U” is described in the authority column corresponding to the sender mail address having update authority to clarify that it has update authority. This address book 500 is stored in the address book folder in the address book folder storage unit 307. By executing the processing as described above, it is possible to determine a source email address of an email that is permitted to be updated once received.

(E-mail transmission processing procedure)
Next, an e-mail transmission processing procedure will be described. FIG. 6 is a flowchart showing the e-mail transmission processing procedure. First, the user determines whether or not it is a transmission mode of an electronic mail to be transmitted, that is, a retransmission mode (step S601). If it is not the re-transmission mode (temporary transmission mode) (step S601: No), the e-mail creation unit 310 creates a temporary transmission mode e-mail (step S602).

  The provisional transmission mode e-mail is an e-mail that may be updated later. Specifically, as shown in FIG. 7, “transmission / temporary transmission” indicating the temporary transmission mode is displayed in the transmission mode display field 701 of the e-mail creation form 700, and necessary items are written in the predetermined field, Create an email. Note that. It is assumed that the same processing is performed when an e-mail is transmitted in the normal transmission mode, which is a general e-mail, without performing temporary transmission. On the other hand, in the case of the retransmission mode (step S601: Yes), the email creation unit 310 creates a retransmission mode email (step S603).

  The re-transmission mode e-mail is an e-mail that is transmitted in order to correct or add to the contents of the provisional transmission mode e-mail transmitted previously. Specifically, as shown in FIG. 8, “Retransmission” indicating the retransmission mode is displayed in the transmission mode display field 701 of the e-mail creation form 700, the description content is updated, and the re-transmission mode e-mail is displayed. create. The update of the description content by the re-transmission mode e-mail allows not only correction / addition / deletion of the description content but also addition of a new attached file. However, it is only possible to add the description to the CC receiver. It should be noted that, in order to clarify the portion that has been updated at this time, it may be displayed by changing the color of characters or the like from other portions that are not updated (for example, displayed in red). Then, the transmission unit 313 transmits the created electronic mail (step S604).

  By executing the processing as described above, it is possible to clearly distinguish whether an electronic mail to be transmitted is scheduled to be updated later or has already been updated. Note that, when an e-mail in the normal transmission mode is transmitted, the e-mail is transmitted in the same format as the temporary transmission mode here. However, the e-mail receiving process described later makes a distinction between the temporary transmission mode and the normal transmission mode.

(E-mail reception processing procedure)
Next, an e-mail reception process procedure will be described. FIG. 9 is a flowchart showing the procedure of this e-mail receiving process. First, the transmission mode detection unit 302 detects whether or not the email received by the reception unit 301 is in the retransmission mode (step S901). When the mode is not the retransmission mode (temporary transmission mode or normal transmission mode) (step S901: No), the transmission mode detection unit 302 displays on the display unit 306 that the received electronic mail is in the temporary transmission mode or the normal transmission mode. At the same time, the electronic mail is sent to the electronic mail storage / deletion processing unit 305 and stored in the inbox folder by the processing of the electronic mail storage / deletion processing unit 305 (step S903). On the other hand, if it is the retransmission mode (step S901: Yes), the process proceeds to step S904.

  In step S901, when the received e-mail is in the retransmission mode (step S901: Yes), the update authority determination unit 303 determines whether the e-mail is an e-mail transmitted from an e-mail address having the update authority. In order to make a determination, the search of the address book 500 is started (step S904). As described above, the address book 500 clearly shows the e-mail transmission source mail address for which the description can be updated. As a result of the processing in step S904, it is detected whether the electronic mail has update authority (step S905).

  If the e-mail has no update authority (step S905: No), the update authority determination unit 303 determines that the e-mail is another newly transmitted e-mail, and displays that fact on the display unit 306 (step S902). The e-mail is sent to the e-mail storage / deletion processing unit 305 and stored in the inbox folder by the process of the e-mail storage / deletion processing unit 305 (step S903). On the other hand, if the e-mail has update authority (step S905: YES), the process proceeds to step S906.

  If it is determined in step S905 that the email has update authority (step S905: Yes), the update target email detection unit 304 is transmitted from the same source email address as the retransmission mode email, and A search is started as to whether or not an unopened temporary transmission mode email of the same subject and the same sender exists in the inbox folder (step S906). As a result of the process in step S906, the presence / absence of the corresponding unopened temporary transmission mode e-mail is detected (step S907).

  If the corresponding unopened temporary transmission mode e-mail does not exist (step S907: No), the update target e-mail detection unit 304 determines that the e-mail is another newly transmitted e-mail, and displays that fact on the display unit 306. The electronic mail is sent to the electronic mail storage / deletion processing unit 305 and stored in the inbox folder by the processing of the electronic mail storage / deletion processing unit 305 (step S903). On the other hand, when the corresponding unopened temporary transmission mode e-mail exists (step S907: Yes), the process proceeds to step S908.

  If there is a corresponding unopened temporary transmission mode e-mail in the process of step S907 (step S907: Yes), the e-mail storage / deletion processing unit 305 moves the e-mail from the inbox folder to the deleted item tray folder. (Step S908). That is, the electronic mail is deleted from the inbox folder. Subsequently, the update target email detection unit 304 displays on the display unit 306 that the retransmission mode email has been received (step S909), and stores and deletes the retransmission mode email as an updated email. The data is sent to the processing unit 305 and stored in the inbox folder by the processing of the e-mail storage / deletion processing unit 305 (step S903). FIG. 10 shows a display example of the browsing screen 1000 displayed on the display unit 306 by the process of step S909.

  The email stored in the inbox folder can be confirmed by clicking on the inbox folder on the email browsing screen (not shown) displayed on the display unit 306. FIG. 11 is an example of a browsing screen 1100 showing the e-mail stored in the inbox folder displayed on the display unit 306 and its transmission mode.

  By executing the processing as described above, even if an e-mail is once sent to the destination, it is possible to correct or add the contents until the recipient opens the e-mail. In this process, it is possible to clearly distinguish whether the received electronic mail is in the temporary transmission mode, the retransmission mode, or the normal transmission mode. Note that the date and time when the updated e-mail is received is the date and time when the provisional transmission mode e-mail is received. Further, the updated date and time may be additionally displayed.

(Prompt mail transmission processing procedure)
In addition, as described above, in this e-mail transmission / reception system, if a re-transmission mode e-mail is not received even after a lapse of a certain period after the provisional transmission mode e-mail is received, the re-transmission mode e-mail is sent to the sender. A reminder email is sent prompting you to send Therefore, here, the procedure for sending the reminder mail will be described. FIG. 12 is a flowchart showing this reminder mail transmission processing procedure.

  First, in order to confirm whether or not there is an unopened temporary transmission mode e-mail in the inbox folder, the temporary transmission mode e-mail detection unit 311 executes a search for the inbox folder every predetermined time (step S1201). ). It should be noted that the time interval at which the provisional transmission mode e-mail detection unit 311 executes the search is arbitrarily set by the user. As a result of the processing in step S1201, it is detected whether there is an unopened temporary transmission mode e-mail (step S1202).

  If there is an unopened temporary transmission mode e-mail (step S1202: Yes), the e-mail creation unit 312 creates an e-mail that prompts the sender to send the re-transmission mode e-mail, and the transmission unit 313 prompts the e-mail. A mail is transmitted (step S1203). In this case, the contents of the temporary transmission mode e-mail received initially or the entire temporary transmission mode e-mail are attached to the reminder mail to be created. On the other hand, when there is no unopened temporary transmission mode e-mail (step S1202: No), the processing is ended as it is.

(Retransmission mode e-mail transmission procedure after receiving the reminder e-mail)
Next, a re-transmission mode e-mail transmission process procedure when a reminder mail is received will be described. FIG. 13 is a flowchart showing a retransmission mode e-mail transmission processing procedure in this case. First, when the transmission mode detection unit 302 detects reception of a reminder email (step S1301), the display unit 306 displays that the reminder email has been received (step S1302). Subsequently, a retransmission mode e-mail creation form 700 as shown in FIG. 8 is displayed on the display unit 306 (step S1303). The user activates the email creation unit 310 to create a retransmission mode email (step S1304). Then, the transmission unit 313 transmits the retransmission mode e-mail (step S1305).

  By executing the process as described above, if an e-mail to be updated later is sent and the e-mail is not updated within a certain period of time, the sender is prompted to update the e-mail. Therefore, e-mail update omission can be avoided.

  As described above, according to the e-mail transmission / reception system, e-mail transmission / reception method, and e-mail transmission / reception program according to the present invention, even if the e-mail is once transmitted to the destination, the recipient opens the e-mail. Until this is done, it will be possible to modify or add to the contents. Also, when an e-mail that is scheduled to be updated later is sent and the e-mail is not updated for a certain period of time, the sender can be urged to do so. be able to. Furthermore, since the e-mail transmitted from the transmission source does not stay in the mail server for a long time and is sent to the transmission destination immediately after the transmission, there is no trouble in emergency contact.

  The e-mail transmission / reception method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.

  As described above, the e-mail transmission / reception system, the e-mail transmission / reception method, and the e-mail transmission / reception program according to the present invention are useful for information transmission by e-mail, and are updated to e-mails that have already been transmitted to the destination. It is suitable when necessary.

It is a figure which shows schematic structure of the electronic mail transmission / reception system concerning embodiment of this invention.
