Japanese Patent Application No. 10-277699
[Problems to be solved by the invention]
However, when an attached file is attached to the text and the e-mail is transmitted by the above-mentioned synchronous e-mail (CC), there is a problem that the attached file is also transmitted to a recipient who does not need it.
[0012]
In general, the data amount of the attached file is large with respect to the mail text, so that the network load is large.
[0013]
Further, for a recipient who does not need an attached file, a large amount of attached file is received in addition to the text, so that the capacity of the disk is squeezed.
[0014]
On the other hand, the above-described conventional e-mail system disclosed in Japanese Patent Application No. 10-277699 embeds an attached document corresponding to a receiving party from an attached document list in a matrix. In such a case, when there are a large number of attached documents, it is not easy to associate the recipient with the attached file, and the recipient of the attached document is erroneously received.
[0015]
The present invention has been made in order to solve the above problems, when sending an e-mail with an attached file in a synchronous mail, the e-mail with the attached file only to the recipient who needs the attached file, An object of the present invention is to provide an e-mail transmission device that can transmit only a body mail to a recipient who does not need an attached file by an easy operation, and can know the recipient who sent the attached file and the recipient who did not.
[0016]
[Means for Solving the Problems]
The e-mail transmission device of the present invention selects a recipient from a recipient list, saves the recipient as a recipient list, allows the user to select a file to be attached, and attaches the selected attached file to a body mail created by e-mail. Means for determining whether there are a plurality of selected recipients in the e-mail transmitting apparatus for transmitting to the selected recipients. Means for displaying an attached recipient selection screen for setting the attachment destination of the attached file, means for saving the address of the attached file recipient selected on the attached recipient selection screen as an attached recipient required list, The recipient list is compared with the recipient list requiring attachment, and the recipient mail which does not have the attached file is attached to the body mail of the recipient who needs the attached file. Message that has an attachment judgment and adds the address of the recipient who needs the attached file to the body mail of the recipient who does not need the attached file. And
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a schematic configuration diagram of an electronic mail transmitting apparatus according to the present embodiment. As shown in FIG. 1, the e-mail device 10 includes an input unit 101, each unit activation control unit 102, a file name selection unit 103, a mail address selection unit 104, a recipient selection unit 105, and the number of recipients with attachment. When the attached file is transmitted to a plurality of addresses by including the determination unit 106, the attachment determination unit 110, the mail creation unit 116, the communication unit 117, etc. Send the body mail with the attached file only to the other party.
[0018]
That is, when there are a plurality of transmission destinations (also called receivers), the transmission determination unit 110 determines the transmission destination that needs the attached file and transmits the file.
[0019]
(Description of each part)
The input unit 101 is connected to a mouse or a keyboard, takes in an input request, and passes it to each unit activation control unit 102.
[0020]
Each unit activation control unit 102 decodes a request from the input unit 101, activates a corresponding process when a mail transmission request is made, and displays data from each unit on the screen 100 in a predetermined format.
[0021]
Upon activation, the file name selection unit 103 displays a screen (not shown) for selecting a desired storage area, and displays a file name (folder) of the selected storage area area (files 118a, 118b,...). The file is displayed on the screen 100 and the file name selected from the input unit 101 (hereinafter, referred to as a selected attached file TMPi) is stored in the selected attached file list 109.
[0022]
The e-mail address selection unit 104 displays the e-mail address of the e-mail address file 119 on the screen 100 upon activation, and stores the e-mail address Hi selected from the input unit 101 in the selected recipient address list 107.
[0023]
When notified by the mail address selection unit 104 that the selection of the recipient address has been completed, the number-of-recipients determination unit 106 refers to the selected recipient address list 107 and determines whether or not there are a plurality of selected recipient addresses Hi. If there is more than one, the receiver selection unit with attachment 105 is activated. If there is only one selected recipient address Hi, the mail creation unit 116 is activated, and the selected attached file TMPi is attached and transmitted.
[0024]
The attached recipient selection unit 105 is activated when there are a plurality of recipients, and displays all recipient addresses in the selected recipient address list 107 on the screen. In addition, a recipient who needs the selected attached file TMPi is designated, and the designated recipient is stored in the attached file required recipient list 108 as an attached file required recipient THi.
[0025]
The attachment judging unit 110 includes an attachment file necessity determination process 111, an attachment file necessity / unnecessary person list creation process 112, and the like. Based on the above, a mail with an attached file or a mail without an attached file is generated in the mail creating unit, divided into a recipient (KHi) that requires an attached file and a recipient (NHi) that does not require an attached file. Let it.
[0026]
Attachment file required person determination processing 111 compares the number of selected recipient addresses Hi in selected recipient address list 107 with the number of attached file required recipients THi in attached file required recipient list 108, and determines whether an attached file is required. It is determined whether or not the recipients are all.
[0027]
If all the recipients need it, the mail creation unit 116 is activated to attach the attached file to all the recipients.
[0028]
If not all of them need an attached file, the attached file required / unnecessary person list creation processing 112 is started.
[0029]
The attached file required / unnecessary person list creation process 112 compares the attached file required recipient THi of the attached file required recipient list 108 with the selected recipient address Hi of the selected recipient address list 107, and requires the attached file. The address of the recipient is stored in the attached file user list 114 as the attached file user KHi, and the address of the recipient who does not require the attached file is stored in the attached file unnecessary person list 113 as the attached file unnecessary person NHi.
[0030]
When the number-of-recipients determining unit 106 determines that the number of recipients is one and the attachment determining unit 111 of the attachment determining unit 110 determines that all of the attachments are received, the mail body 115 generated on the screen is displayed. After encoding the selected attached file TMPi in the selected attached file list 109, it attaches it to the mail body 115, saves it as a temporary standby mail Mi, reads the server setting data, and sends it to the communication unit 117.
[0031]
That is, the e-mail creating unit 116 includes an e-mail for unattached persons and an e-mail for attaching persons. A mail with the address KHi of the person who attached the file in the sender list 114 added to the body is created and transmitted using the communication unit 117.
[0032]
Attachment person mail creation processing sets the address of the attachment file person KHi to “attached”, creates an e-mail in which the address NHi of the person unnecessary for the attachment file in the attachment file unnecessary person list 113 is added to the main body, and creates the e-mail. Is transmitted using.
[0033]
After connecting to the ISP, the communication unit 117 reads the server setting data and transmits the temporary standby mail Mi.
[0034]
The operation of the mail transmission device configured as described above will be described below with reference to the flowcharts of FIGS. 2, 3, and 4.
[0035]
First, when a command for creating a mail is input from the input unit 101, each unit activation control unit 102 displays a link mail screen shown in FIG.
[0036]
In this state, the file selection unit 103 monitors whether a storage area in which data is stored is selected (S201).
[0037]
In this embodiment, the file name selection unit 103 opens a screen for selecting a desired storage area (not shown). It is assumed that a file name (folder) of a desired storage area (files 118a, 118b,...) Is selected from this screen.
[0038]
In step S201, when a storage area is selected by the input unit 101, the file name selection unit 103 reads a list of data names (folders) stored in the storage area from the file 118 and displays the list on the screen 100 ( S202).
[0039]
Then, the file selected by the input unit 101 is stored as the selected attached file TMPi in the selected attached file list 109, and the selected attached file TMPi is written in the attached file name area G1 of FIG. 5 (S203). In this embodiment, the number of the selected attached file TMPi is one (hereinafter referred to as TMP1).
[0040]
Next, the e-mail address selection unit 104 opens the e-mail address list of the e-mail address file 119 on the screen 100 (S204), and selectively receives the selected e-mail address (hereinafter referred to as selected recipient address Hi) from the input unit 101. Is stored in the recipient address list 107 and written in the recipient address column G2 in FIG. 5 (S205).
[0041]
Then, when notified that the selection of the recipient address has been completed from the mail address selection unit 104, the number-of-recipients determining unit 106 refers to the selected recipient address list 107 and determines whether or not there are a plurality of selected recipient addresses Hi. A determination is made (S206).
[0042]
If it is determined in step S206 that there is a plurality of recipients, the receiver selection unit with attachment 105 is activated. When there are a plurality of selected recipient addresses Hi, the attached recipient selection unit 105 displays an attachment destination selection button Bi in the area G3 as shown in FIG. 6 (S207).
[0043]
Next, when the attachment destination selection button Bi is selected, the attachment-attached recipient selection unit 105 displays an address selection dialogue for attaching an attached file shown in FIG. 7 on the screen (S209). For example, as shown in FIG. 6 in the selected recipient address list 107, three selected recipient addresses H1 (address1@domain.co.jp), selected recipient addresses H2 (address2@domain.co.jp), and selective reception If there is a recipient address H3 (address3@domain.co.jp), these are displayed in the address selection dialog, and the selected recipient address Hi selected from these is saved in the recipient list 108 requiring attachment file (attachment file). The required recipients TH1, TH2, and TH3) (S210). In this embodiment, it is assumed that the selected recipient addresses H1, H3, H4 have been selected.
[0044]
Next, the attached file requester determination process 111 of the attachment determiner 110 determines the number of selected recipient addresses Hi in the selected recipient address list 107 and the number of attached file recipients THi in the attached file recipient list 108. To determine whether all the recipients need the attached file (S211).
[0045]
If it is determined in step S211 that all the recipients need the attached file (when Hi is three and THi is three), the mail creation unit 116 is activated to create a mail (S212). For example, a mail R0 for "send with an attached file" is created (see FIG. 6).
[0046]
The mail creating unit 116 reads the actual data of the selected attached file TMP1 stored in the selected attached file list 109 from the file 118, and encodes the data (S213).
[0047]
Next, the encoded attached file is attached to the mail body Ro created in step S212 (S214), and the selected recipient addresses HI, H2, and H3 are set to the addresses to which the attached file is attached (all recipients receive the attached file). Is required) (S215).
[0048]
Next, after setting each selected recipient address THi to an address to which an attached file is attached, the mail R0 is stored in the server as a transmission standby mail M1 (S216).
[0049]
The communication unit 117 starts the connection to the ISP and transmits the stored transmission standby mail M1 (S217). That is, the attached file is transmitted to the three recipients.
[0050]
Also, in step S211, when the attached file user determination process 111 determines that the attached file is not attached to all the selected recipient addresses Hi (for example, the number of the selected recipient addresses is three and the attached file required recipients THi are not included). 1), the attached file required / unnecessary person list creation unit 112 of the attachment determining unit 110 compares the attached file required recipient THi of the attached file required recipient list 108 with the selected recipient address Hi of the selected recipient address list 107. Then, the attached-file-recipient-recipient THi requiring the attached file is stored in the attached-file-requirer list 114 as the attached-file-requirer KHi (S220). In addition, the selected recipient address Hi that makes the attached file unnecessary is stored in the attached file unnecessary person list 113 as the attached file unnecessary person NHi (S221).
[0051]
On the other hand, as shown in FIG. 3, when notified that there are some recipients who do not attach the attached file, the mail creating unit 116 executes the mail creating process for the unnecessary attachment person and the mail creating process for the person requiring the attached mail. Do.
[0052]
In the e-mail creation process for unnecessary attachments, the unnecessary attachment list 113 is read (S301), and the unnecessary attachment unnecessary person NHi to which no attached file is attached is set to no attached file (S302). For example, in the present embodiment, address1 @ domain. co. jp is stored as NH1 in the attached file unnecessary person list, and address2 @ domain. co. jp and address3 @ domain. co. jp and are stored as attachment file holders KH2 and KH3, address1 @ domain. co. jp, NH1 is set without an attached file.
[0053]
Next, a mail body R1 “No attached file” is created (S303), and address2 @ domain. co. jp and address3 @ domain. co. jp is copied and added (S304). For example, the mail text R1 shown in FIG. 8 is generated. That is, as shown in FIG. 8, the recipient address to which the attached file is attached is added to the text. For this reason, the recipient can know who sent the necessary attachment. Also, since the attached file is not transmitted to address1, the recipient on address1 can reduce the capacity.
[0054]
Next, the communication unit 117 stores the mail text R1 as the standby mail M1 (S305), and after connecting to the ISP (S306), transmits the standby mail M1 to the server (S307).
[0055]
On the other hand, the attachment requester mail creation process reads the file from the attached file requester list 114 (S310), and sets these recipient addresses to the presence of the attached file (S311). For example, address1 @ domain. co. jp and address3 @ domain. co. jp is set in the attached file owner list 114, address1 @ domain. co. jp and address3 @ domain. co. jp is set to have an attached file.
[0056]
Next, an e-mail text R2 is created (S312), and an attached file unnecessary person NH2 of the attached file unnecessary person list 113 is added to this text R2 (see FIG. 9) (S313).
[0057]
Next, the attached mail temp1 is encoded (S314), and an attached file is attached (S315). Next, the mail is stored as a transmission standby mail M2 (S316), connected to the ISP (S317), and the standby mail is transmitted. Therefore, address1 @ domain. co. jp and address3 @ domain. co. The recipient of jp knows to whom the attached mail was not attached and sent.
[0058]
When the number-of-recipients determining unit 106 determines in step S206 that the transmission address Hi is not plural (for example, when the attached file is transmitted only to address1@domain.co.jp), the mail creating unit 116 is activated. Then, the recipient address is notified.
[0059]
The mail creating unit 116 sets this recipient address to the presence of the attached file (S401). For example, address1 @ domain. co. jp is set to include an attached file.
[0060]
Next, a mail body R is created (402), the attached file TMPi attached to the body R is encoded (S403), and an attached file is attached (S404). Next, the mail is stored as a transmission standby mail M (405), connected to the ISP (S406), and the standby mail is transmitted (S407).
[0061]
Here, a basic exchange between the client terminal and the server will be described with reference to FIG.
[0062]
The mail client is willing to connect to the mail server using TCP. That is, a virtual line is secured between the two terminals.
[0063]
Next, two machines should be able to communicate one-on-one, and exchange SMTP commands and their response messages.
Then, when connected by TCP, the server returns its own domain name, server software name, version, and the like.
[0064]
Then, when the He command and the domain name are transmitted from the mail command, “OK” is returned from the server.
[0065]
The mail client then sends the recipient's mail address to the mail server using the MALL FROM command.
[0066]
Then, the destination of the mail is specified (RCPT TO command). Next, the main body of the mail is declared to be transmitted to the server (DATA command), and when "OK" is returned, the main body of the mail is transmitted to the server.
[0067]
When the transmission of the mail body is completed, a period, a line feed code, etc. are sent, the SMTP connection is terminated by the QUIT command, and the TCP connection is disconnected.
[0068]
【The invention's effect】
As described above, according to the present invention, when there are a plurality of recipients sending an e-mail, and when there is an attached mail, an attachment recipient selection screen for attaching an attached file among these recipients is displayed. Then, the user is required to input the recipient who needs the attached file and the recipient who does not need the attached file.
[0069]
Then, add the recipient address that does not attach the attachment to the body mail of the recipient who needs the attached file, and add the recipient address that needs the attached file to the body mail of the recipient who does not need the attached file. Add the address and send.
[0070]
Therefore, since only the text is transmitted to the recipient who does not need the attached file, the effect of not squeezing the capacity of the disc is obtained.
[0071]
In addition, there is an effect that the person who sent with the attached file and the person who sent without the attached file can be identified by the contents of the body mail.
