  Next, the operation will be described.

  FIG. 10 is a flowchart for explaining an operation example of the communication system. Specifically, it is a flowchart for explaining an operation example when the client 1 transmits mail.

  In step S <b> 1, the sender uses the operation unit 13 to request activation of a program that implements the mailer unit 14. In response to the request, the computer reads the program from the recording medium and activates the program to realize the mailer unit 14.

  Subsequently, in step S <b> 2, the sender uses the operation unit 13 to request mail generation. In response to the request, the mail processing unit 170 generates the mail 5 and displays a mail creation screen on the display unit 12.

  FIG. 11 is an explanatory diagram showing an example of a mail creation screen. In FIG. 11, the mail creation screen 1100 includes a send button 1101, a title box 1102, a destination box 1103, a selection button 1104, a text description area 1105, and an attached file area 1106.

  The send button 1101 is a button for requesting mail transmission. A title box 1102 is an input box for inputting a title of the mail. A destination box 1103 is an input box for inputting a mail destination. A selection button 1104 is a button for requesting display of an attached file selection dialog. A text description area 1105 is an area for inputting the text of an email. The attached file area 1106 is an area for designating an attached file to be attached to the mail.

  When the mail creation screen is displayed, the sender uses the operation unit 13 to input the text of the mail 5 in the text description area 1105. The mail processing unit 170 adds the mail text to the mail 5.

  Subsequently, in step S <b> 3, the sender sets a file in the attachment file area 1106 using the operation unit 13, thereby specifying an attachment file to be attached to the mail 5.

  Hereinafter, it is assumed that the sender designates attachment files 6 and 7 as attachment files. In the following, the file name of the attached file 6 is “attached file A”, and the file name of the attached file 7 is “attached file B”. Further, the update date and time of the attached files 6 and 7 are both “2007/07/08 17:36”.

  The mail processing unit 170 attaches the attached files 6 and 7 to the mail 5 according to the designation.

  Subsequently, in step S <b> 4, the sender uses the operation unit 13 to input the title of the mail 5 (for example, a conference opening notification) in the title box 1102. The mail processing unit 170 adds the input title to the header of the mail 5.

  Subsequently, in step S <b> 5, the sender uses the operation unit 13 to input a mailing list (zzz@zzzz.com) in the destination box 1103. The mail processing unit 170 adds the input mailing list to the header of the mail 5 as a destination.

  Subsequently, in step S6, the sender determines whether or not to select an individual attached file for each mail address belonging to the mailing list.

  If the sender determines that the individual attached file is selected, step S7 is executed. If the sender determines that the individual attached file is not selected, step S9 is executed.

  In step S <b> 7, the sender uses the operation unit 13 to press the selection button 1104 to request display of the attached file selection dialog. The dialog processing unit 140 displays an attached file selection dialog on the display unit 12 in response to the request.

  Subsequently, in step S8, the sender uses the operation unit 13 to select an individual attached file. The dialog processing unit 140 converts the selection result into data and generates extended information. The mail processing unit 170 generates an extension header including the extension information, and sets the extension header in the mail 5.

  In step S <b> 9, the sender uses the operation unit 13 to press the send button 1101 to request mail transmission. The mail processing unit 170 transmits the mail 5 to the mail server 2 in response to the request.

  Next, the operation of steps S7 to S9 will be described in more detail.

  12 and 13 are flowcharts for explaining detailed operation examples of steps S7 to S9.

  When the sender uses the operation unit 13 to request display of the attached file selection dialog, the mail processing unit 170 executes Step T1.

  In step T1, the mail processing unit 170 transmits the mailing list input in step S5 of FIG. When receiving the mailing list, the request unit 110 generates an acquisition request including the mailing list. The request unit 110 transmits the generated acquisition request to the reception unit 21 of the mail server 2.

  Next, in step T2, the accepting unit 21 accepts an acquisition request.

  Subsequently, in step T <b> 3, the reception unit 21 transmits the acquisition request to the ML member processing unit 22. When the ML member processing unit 22 receives the acquisition request, the ML member processing unit 22 acquires, as member information, the mail address associated with the mailing list in the acquisition request from the member DB 20.

  Subsequently, in step T4, the ML member processing unit 22 transmits the member information to the notification unit 23. When the notification unit 23 receives the member information, the notification unit 23 transmits the member information to the ML member reception unit 120 of the client 1.

  Subsequently, in step T5, the ML member receiving unit 120 receives member information.

  Turning to FIG. In step U1, the ML member receiving unit 120 transmits the member information to the file processing unit 130.

  When the file processing unit 130 receives the member information, the file processing unit 130 transmits to the mail processing unit 170 that the identifier of the attached file (a combination of the file name and the update date / time) is acquired. When the mail processing unit 170 accepts that fact, the mail processing unit 170 transmits two identifiers attached to each of the attached files 6 and 7 to the file processing unit 130. Hereinafter, the identifiers of the attached files 6 and 7 may be referred to as an identifier A and an identifier B, respectively.

  When the file processing unit 130 receives the identifiers A and B, the file processing unit 130 searches each mail address indicated by the member information from the attached file information in the file DB 11.

  Subsequently, in step U2, the file processing unit 130 determines whether at least one of the identifiers A and B is associated with each searched mail address.

  If at least one of the identifiers A and B is associated with at least one of the retrieved email addresses, the file processing unit 130 determines that there is an attached file that has been transmitted, and executes Step U3.

  On the other hand, if none of the identifiers A and B are associated with the retrieved mail address, the file processing unit 130 determines that there is no attached file that has been transmitted, and executes Step U4.

  In step U3, the file processing unit 130 extracts transmitted file information from the attached file information in the file DB 11.

  For example, when the attached file information in the file DB 11 is the attached file information 200 shown in FIG. 2, the file processing unit 130 operates as follows. The identifier A is “file name“ attached file A ”and update date“ 2007/07/08 17:36 ””, and the identifier B is “file name“ attached file B ”and update date“ 2007/07 / 08 17:36 "".

  In this case, the file processing unit 130 determines that the identifier A “file name“ attached file A ”and update date“ 2007/07/08 17:36 ”” and the identifier A are associated with the mail address “ddd@ddd.com”. "Is extracted as transmitted file information. The extracted transmitted file information is the same as the transmitted file information 300 in FIG.

  Thereby, it is understood that it is not necessary to send the attached file 6 with the identifier A to the mail address “ddd@ddd.com”.

  Subsequently, in step U4, the file processing unit 130 transmits the member information and the identifiers A and B to the dialog processing unit 140. At this time, if the file processing unit 130 has extracted the transmitted file information in step U3, the file processing unit 130 further transmits the transmitted file information. Hereinafter, it is assumed that the file processing unit 130 further transmits the transmitted file information.

  When the dialog processing unit 140 receives the member information, the identifiers A and B, and the transmitted file information, the dialog processing unit 140 generates an attached file selection dialog using the member information and the identifiers A and B.

  The dialog processing unit 140 suppresses the selection operation for the selection area specified by the transmitted file information in the generated attached file selection dialog.

  Specifically, the dialog processing unit 140 selects an attached file with an identifier associated with the mail address in the transmitted file information from the selection areas determined for the mail address in the transmitted file information. Suppresses selection operations for selected areas.

  The dialog processing unit 140 displays the attached file selection dialog on the display unit 12.

  Subsequently, in step U5, the sender uses the operation unit 13 to perform a selection operation on the selection area of the attached file selection dialog, so that each e-mail address indicated by the member information is addressed to the e-mail address. Select individual attachments to send to.

  For example, in the case of the attached file selection dialog 400 shown in FIG. 4, first, for the mail address 401 to which the attached file 6 is transmitted, a check operation is performed on the check box 402 of the mail address 401 to send the attached file 7. A check operation is performed on the check box 403 of the mail address 401 for the address 401.

  At this time, when a check operation is performed as shown in FIG. 4, the attached file is not transmitted to the mail address “aaa@aaa.com”. The attached files 6 and 7 are transmitted to the mail address “bbb@bbb.com”. Further, only the attached file 6 is transmitted to the mail address “ccc@ccc.com”. Then, only the attached file 7 is transmitted to the mail address “ddd@ddd.com”.

  Subsequently, the sender uses the operation unit 13 to press the OK button 404 to end the selection of the individual attached file.

  When the selection of the individual attached file is completed, the dialog processing unit 140 converts the selection result selected by the operation unit 13 into data, and generates extended information.

  For example, in the case of the extended information 500 illustrated in FIG. 5, the dialog processing unit 140 performs the following processing for each mail address 501.

  First, the dialog processing unit 140 associates the attached file A flag 502 and the attached file B flag 503 “off” with the mail address.

  Then, when the attached file 6 of “attached file A” is selected for the mail address, the dialog processing unit 140 turns on the attached file A flag 502. Further, when the attached file 7 of “attached file B” is selected for the mail address, the dialog processing unit 140 turns on the attached file B flag 503.

  Subsequently, in step U6, the dialog processing unit 140 generates an extension header including the generated extension information, and sets the extension header in the mail 5 generated in step S2 of FIG.

  Subsequently, in step U <b> 7, the sender uses the operation unit 13 to press the send button 1101 to request transmission of the mail 5. The mail processing unit 170 transmits the mail 5 to the mail transmission unit 180 in response to the request. When the mail transmission unit 180 receives the mail 5, the mail transmission unit 180 transmits the mail 5 to the mail reception unit 24 of the mail server 2.

  Subsequently, in step U8, the mail processing unit 170 transmits the extension information and the identifier of each attached file of the flag in the extension information to the update unit 160. When receiving the identifier and the extension information, the update unit 160 generates attachment file information based on the identifier and the extension information. For example, the mail processing unit 170 generates attachment file information by associating the file identifier of the flag indicating ON with the mail address associated with the flag in the extension information.

  The mail processing unit 170 stores the generated attached file information in the file DB 11 and updates the attached file information in the file DB 11. Thereby, the operation at the time of mail transmission by the client 1 is completed.

  Next, the operation of the mail server 2 when the mail 5 is received will be described.

  FIG. 14 is a flowchart for explaining an operation example of the mail server 2 when the mail 5 is received.

  In step V1, the mail receiving unit 24 receives the mail 5.

  Subsequently, in step V <b> 2, the mail receiving unit 24 transmits the mail 5 to the analyzing unit 26. When receiving the mail 5, the analysis unit 26 extracts one record from the extension information in the extension header of the mail. In the record, a flag is associated with each mail address.

  Subsequently, in step V3, the analysis unit 26 analyzes the set of the attached file A flag and the attached file B flag in the record, and executes any one of steps V4 to V7 according to the analysis result.

  Specifically, the analysis unit 26 determines the value of the set of the attached file A flag and attached file B flag corresponding to the mail address in the record.

  The analysis unit 26 executes Step V4 when the set of the attached file A flag and the attached file B flag is “0, 0”, and executes Step V5 when the set is “1, 0”. If the set is “0, 1”, step V6 is executed, and if the set is “1, 1”, step V7 is executed.

  In step V4, the analysis unit 26 duplicates the main body of the mail 5, and sets the mail address in the record as the destination of the duplicate mail.

  The analysis unit 26 transmits the copied mail to the mail transmission unit 27. The mail transmission unit 27 transmits the mail to the mail address that is the destination of the mail. Thereafter, Step V8 is executed.

  In step V5, the analysis unit 26 duplicates the main body of the mail 5, and sets the mail address in the record as the destination of the copied mail. The analysis unit 26 duplicates the attached file 6 attached to the mail 5 and attaches the duplicated attached file 6 to the duplicated mail.

  The analysis unit 26 transmits a mail with the attached file 6 attached thereto to the mail transmission unit 27. The mail transmission unit 27 transmits the mail to the mail address that is the destination of the mail. Thereafter, Step V8 is executed.

  In step V6, the analysis unit 26 duplicates the main body of the mail 5, and sets the mail address in the record as the destination of the copied mail. The analysis unit 26 duplicates the attached file 7 attached to the mail 5 and attaches the duplicated attached file 7 to the duplicated mail.

  The analysis unit 26 transmits a mail with the attached file 7 attached thereto to the mail transmission unit 27. The mail transmission unit 27 transmits the mail to the mail address that is the destination of the mail. Thereafter, Step V8 is executed.

  In step V7, the analysis unit 26 duplicates the main body of the mail 5, and sets the mail address in the record as the destination of the copied mail. The analysis unit 26 duplicates the attached files 6 and 7 attached to the mail 5 and attaches the duplicated attached files 6 and 7 to the duplicated mail.

  The analysis unit 26 transmits the mail attached with the attached files 6 and 7 to the mail transmission unit 27. The mail transmission unit 27 transmits the mail to the mail address that is the destination of the mail. Thereafter, Step V8 is executed.

  In step V8, the analysis unit 26 determines whether there is a record different from the extracted record in the extended information. If there is such a record, the analysis unit 26 executes Step V9. If there is no such record, the analysis unit 26 ends the operation.

  In step V9, the analysis unit 26 extracts a record different from the extracted record. Thereafter, the analysis unit 26 executes Step V3.

  In the present embodiment, a communication system is used in which the sender transmits the mail 5 attached with two attachment files to a mailing list having four members, but the mail attached with N attachment files is M. It may be replaced with a communication system that transmits to a mailing list having human members. Note that N is an integer of 0 or more, and M is an integer of 1 or more.

  The mailer unit 14 may be realized by using dedicated hardware.

  Next, the effect will be described.

  According to the present embodiment, the operation unit 13 selects, for each mail address belonging to the mailing list, an attached file to be transmitted to the mail address in accordance with a user operation. The dialog processing unit 140 generates extended information indicating the selection result of the operation unit 13. The mail transmission unit 180 transmits the extended information, the mail, and the selected file to the mail server 2. The mail receiving unit 24 of the mail server 2 receives the extended information and mail. The individual transmission unit 25 transmits each of the attached files attached to the mail received by the mail receiving unit 24 to the mail address corresponding to the attached file indicated by the extended information received by the mail receiving unit 24. .

  In this case, for each mail address belonging to the mailing list, a file to be transmitted to the mail address is selected according to a user operation. Also, extended information indicating the selection result is generated. Further, an attached file corresponding to the mail address indicated by the extended information is transmitted to each mail address belonging to the mailing list.

  Therefore, if the user selects a different file for each member of the mailing list, it is possible to transmit a different attachment file for each member of the mailing list.

  In the present embodiment, the operation unit 13 selects a desired number of files for each mail address belonging to the mailing list.

  For this reason, it is possible to transmit a different number of attached files for each member of the mailing list.
