  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

(First embodiment)
First, based on FIG. 1, the mail transmission system 100 concerning the 1st Embodiment of this invention is demonstrated. In the mail transmission system 100 according to the first embodiment, a case where the mail transmission server 120 has a function of preventing erroneous mail transmission is shown. Here, FIG. 1 is a block diagram showing a configuration of the mail transmission system 100 according to the present embodiment.

  As shown in FIG. 1, the mail transmission system 100 according to the present embodiment includes a mail client terminal 110 that is a communication terminal device, and a mail transmission server 120 that performs an e-mail transmission process. The e-mail created by the user using the mail client terminal 110 is transmitted to the mail transmission server 120 connected to the mail client terminal 110 via the LAN 140, for example. The mail transmission server 120 can send and receive external computer information via the general-purpose network 130.

  The mail client terminal 110 is a terminal for creating an e-mail. For example, a display unit such as a display for displaying information, an input unit for a user to input information, and information input by the user or an external device And a control unit (none of which is shown) for processing the processed information. The mail client terminal 110 can be exemplified by a personal computer, for example.

  The mail transmission server 120 is a server that performs mail transmission processing. For example, the mail transmission / reception unit 121, the address extraction unit 122, the display name match determination unit 123, the warning notification unit 124, the mail address storage unit 125, , And a title storage unit 126.

  The mail transmission / reception unit 121 is a transmission / reception unit that receives an electronic mail created in the mail client terminal 110 and transmits it to an external mail client terminal via the general-purpose network 130. When the e-mail transmission / reception unit 121 according to the present embodiment receives an e-mail from the e-mail client terminal 110, the e-mail transmission / reception unit 121 extracts an e-mail address in the body of the e-mail to the e-mail extraction unit 122 in order to check whether the e-mail address is correct Let

  The address extraction unit 122 is an extraction unit that extracts an address described in the text of an electronic mail. The address extraction unit 122 searches for the title stored in the title storage unit 126 from the text of the e-mail, and extracts the word / phrase described immediately before the searched title as the address.

  The display name match determination unit 123 determines whether the address extracted by the address extraction unit 122 matches the display name associated with the mail address selected by the user in the mail address storage unit 125. It is. If the display name match determination unit 123 determines that there is no match in the matching process between the address in the mail text and the display name indicating the e-mail transmission destination, there is a possibility that the e-mail transmission destination is incorrect. Assuming that there is a warning, the warning notification unit 124 described later causes the mail client terminal 110 to notify the warning.

  The warning notification unit 124 notifies the user of a warning when the address extracted by the address extraction unit 122 in the display name match determination unit 123 does not match the display name indicating the destination of the created e-mail. It is a notification unit. The warning notification unit 124 notifies a warning to the user via the mail client terminal 110. Upon receiving the warning notification, the mail client terminal 110 prompts the user to confirm the destination of the e-mail by displaying a warning screen on the display unit (not shown) or generating a warning sound, for example. .

  The mail address storage unit 125 is a storage unit that stores a mail address that is a destination of an email in association with a display name that represents the destination of the email, and includes, for example, a memory such as a RAM or a hard disk. FIG. 2 shows an example of the mail address storage unit 125. As shown in FIG. 2, in the mail address storage unit 125, for example, a display name 125a displayed as a transmission destination at the time of mail creation or after mail transmission is stored in association with the mail address 125b. When creating an electronic mail, the user can select a destination mail address from the mail address storage unit 125.

  The title storage unit 126 is a storage unit that stores a title, and includes, for example, a memory such as a RAM or a hard disk. FIG. 3 shows an example of the title storage unit 126. As shown in FIG. 3, the inheritance storage unit 126 stores, for example, honorifics 126a such as “sama”, “sama”, “dono”, “what”, “san”, “to”.

  Next, a mail transmission method executed by the mail transmission system 100 configured with such a mail client terminal 110 and a mail transmission server 120 will be described with reference to FIGS. Here, FIG. 4 is a flowchart showing a mail transmission method in the mail transmission system 100 according to the present embodiment. FIG. 5 is an explanatory diagram showing an example of the electronic mail 111. Further, FIG. 6 is an explanatory diagram showing an example of a warning notified to the user via the mail client terminal 110 when there is a warning by the warning notification unit 124.

  As shown in FIG. 4, first, the user creates an electronic mail 111 using the mail client terminal 110 (step S101; mail creation step). For example, information (for example, the contents shown in FIG. 2) stored in the mail address storage unit 125 is displayed on the mail client terminal 110, and the user selects a transmission destination from the displayed information. Can be input. When the user inputs the destination of the email 111, the display name stored in the email address storage unit 125 is displayed in the destination display column 112a of the header 112 of the email 111, as shown in FIG. For example, assume that the user selects the mail address “suzuki2541@oki.co.jp” or the display name “Ichiro Suzuki” associated with the mail address from the mail address storage unit 125. At this time, the display name “Ichiro Suzuki” is displayed in the address display column 112a of the e-mail 111.

  Next, after the user creates the electronic mail 111, for example, when an instruction to transmit the electronic mail 111 is made by clicking a transmission icon, the electronic mail 111 is transmitted from the mail client terminal 110 to the mail transmission server 120 (step S103). Mail sending step).

  The mail transmission / reception unit 121 of the mail transmission server 120 that has received the electronic mail 111 checks whether there is an error in the transmission destination of the electronic mail 111. In this check, first, it is determined whether or not an address is described in the text 113 of the received electronic mail 111 (step S105; address extraction step). The e-mail 111 is roughly divided into a header portion 112 in which a sender, a destination, and the like are described, and a text 113 in which a user describes a sentence and the like. The address extraction unit 122 according to the present embodiment searches for an address from the text 113 of the electronic mail 111.

  The address extraction unit 122 extracts the address based on the title stored in the title storage unit 126. Specifically, the title stored in the title storage unit 126 is searched in the body 113 of the e-mail 111, and the word / phrase described immediately before the searched title is extracted as the address. For example, as shown in FIG. 5, if the address extractor 122 searches for the title 113a “san” from the text 113 of the e-mail 111, “Yamada” described immediately before the title 113a “san” will be displayed. Extracted as address. When the address is extracted in this way, it is determined that the address is described.

  Here, when extracting the address described in the text 113 of the electronic mail 111, the address extracting unit 122 may search for the beginning of the text 113. The address of the e-mail 111 is usually written at the beginning of the body 113 of the e-mail 111. The beginning part is a predetermined part that starts from the beginning position of the body 113 of the e-mail 111. For example, the first section 113b from the beginning position of the body of the e-mail until a break such as a blank line appears, or the beginning A portion 113c from a line to several lines (for example, the fifth line) can be used. This eliminates the need to search the entire text 113 of the e-mail 111, thereby reducing the time required for searching and eliminating unnecessary processing. However, the entire body 113 of the e-mail 111 may be searched as necessary.

  If it is determined in step S105 that the address is described in the body text 113 of the e-mail 111, the display name match determination unit 123 displays the display name displayed in the address display column 112a of the e-mail 111 and the address. It is determined whether or not the address extracted by the extraction unit 122 matches (step S109; display name match determination step). The display name and the address do not need to be completely matched. For example, if the last name matches, the display name and the address may be determined to match. For example, in FIG. 5, the display name displayed in the destination display field 112a of the e-mail 111 is “Ichiro Suzuki”, and the address extracted by the address extraction unit 122 is “Yamada”. In this case, the display name match determination unit 123 determines that the display name and the address do not match.

  If it is determined in step S109 that the display name displayed in the destination display field 112a of the electronic mail 111 does not match the address extracted by the address extraction unit 122, the warning notification unit 124 sends the mail client terminal 110. A warning is sent to (step S111; warning notification step). On the other hand, if it is determined in step S109 that the display name displayed in the address display column 112a of the email 111 matches the address extracted by the address extracting unit 122, a process of transmitting the email 111 is performed. Perform (step S107; mail transmission step).

  Thereafter, the mail client terminal 110 that has received the warning notification from the warning notification unit 124 of the mail transmission server 120 notifies the user of the warning (step S113; warning display step). Examples of means for notifying the user by the client terminal 110 include means for issuing a warning sound and means for displaying a warning screen 115 as shown in FIG. When the warning screen 115 is displayed, the warning screen 115 can display, for example, a message prompting the user to confirm, selection buttons 115a and 115b for allowing the user to decide subsequent processing, and the like.

  Then, the user determines whether or not to send the electronic mail 111 by pressing the selection buttons 115a and 115b on the warning screen 115 (step S115; confirmation step). The user presses the send button 115a when determining that the e-mail 111 can be transmitted as it is, and presses the cancel button 115b when determining that the e-mail 111 is not transmitted. When the send button 115a is pressed, a mail transmission instruction is transmitted to the mail transmission server 120, and the mail transmission server 120 that has received the mail transmission instruction transmits the electronic mail 111 (step S107).

  On the other hand, when the cancel button 115b is pressed, the mail client terminal 110 transmits a mail deletion request to the mail transmission server 120, for example (step S117; deletion request step). Then, the mail transmission server 120 that has received the mail deletion request performs a process of deleting the electronic mail 111 (step S119; mail deletion step). Therefore, the electronic mail 111 is not transmitted. When the cancel button 115b is pressed, the e-mail 111 may not be deleted, the mail transmission process may be interrupted, and the e-mail 111 may be modified.

  If it is determined in step S105 that the address 113 is not described in the text 113 of the e-mail 111, for example, as shown in FIG. 4, the e-mail 111 is transmitted without confirmation from the user. Processing may be performed (step S107), and the warning notification unit 124 may notify the mail client terminal 110 of a warning to confirm the address.

  As described above, in the mail transmission system 100 according to the present embodiment, the mail transmission server 120 performs destination confirmation processing for preventing erroneous transmission of electronic mail.

  The mail transmission system 100 according to the first embodiment has been described above. According to the mail transmission system 100, whether or not there is an erroneous transmission of the e-mail 111 is confirmed by checking whether or not the destination in the body 113 of the e-mail 111 matches the display name indicating the e-mail transmission destination. Is judged. Therefore, even when the user mistakenly selects the transmission destination of the electronic mail 111 from the mail address storage unit 125, it is possible to reliably prevent erroneous transmission with such a simple configuration. In addition, since the mail transmission server 120 is provided with a mail erroneous transmission check function, it is not necessary to have a function related to each mail client terminal 110. For example, a configuration suitable for a system that manages messages such as Web mail on the server side. ing.

(Second Embodiment)
Next, based on FIG. 7, the mail transmission system 200 concerning the 2nd Embodiment of this invention is demonstrated. The mail transmission system 200 according to the present embodiment shows a case where the mail client terminal 210 has a function of preventing erroneous mail transmission. Here, FIG. 7 is a block diagram showing a configuration of the mail transmission system 200 according to the present embodiment. In the mail transmission system 200, detailed description of the same components as those in the first embodiment is omitted.

  As shown in FIG. 7, the mail transmission system 200 according to the present embodiment includes a mail client terminal 210 that is a communication terminal device, and a mail transmission server 220 that performs an e-mail transmission process. The e-mail created by the user using the mail client terminal 210 is transmitted to the mail transmission server 220 connected to the mail client terminal 210 via the LAN 240, for example. The mail transmission server 220 can transmit and receive external computer information via the general-purpose network 230.

  The mail client terminal 210 is a terminal for creating an electronic mail. For example, the mail client terminal 210 is a mail transmission unit 211, an address extraction unit 212, a display name match determination unit 213, a warning notification unit 214, and a mail address storage unit 215. And a title storage unit 216 and a mail creation unit 217. Further, for example, a display unit (not shown) such as a display for displaying information such as a warning may be further provided. Examples of the mail client terminal 210 include a personal computer. Note that the mail transmission unit 211, the address extraction unit 212, the display name match determination unit 213, the warning notification unit 214, the mail address storage unit 215, and the title storage unit 216 are the same as the components described in the first embodiment. Therefore, detailed description is omitted. The mail creation unit 217 is a creation unit that creates an email, and creates an email from information input by a user using a screen as shown in FIG. 5, for example.

  The mail transmission server 220 is a server that performs mail transmission processing. The mail transmission server 220 receives the electronic mail transmitted from the mail client terminal 210 and performs processing of transmitting to the external mail client terminal via the general-purpose network 230.

  In the mail transmission system 200 configured as described above, the e-mail created at the mail client terminal 210 confirms the e-mail transmission destination at the mail client terminal 210. First, an e-mail is created by the mail creation unit 217 based on information input by the user using the mail client terminal 210 (mail creation step). For example, information (for example, the contents shown in FIG. 2) stored in the mail address storage unit 215 is displayed on the mail client terminal 210, and the user selects a transmission destination from the displayed information. Can be entered. When the user inputs an e-mail transmission destination, the display name stored in the e-mail address storage unit 215 is displayed in the destination display field of the e-mail header.

  Next, after the user creates an e-mail, for example, when an e-mail transmission instruction is made by clicking a transmission icon, the mail client terminal 210 checks whether there is an error in the e-mail transmission destination. At this time, first, the address extracting unit 212 extracts the address, and determines whether or not the address is described in the body of the e-mail (address extracting step). The processing in the address extracting step is the same as that of the first embodiment. Since this is the same as step S105, a detailed description thereof is omitted here.

  When it is determined in the address extraction step that the address is described in the body of the e-mail, the display name match determination unit 213 displays the display name displayed in the e-mail address display field and the address extraction unit 212. It is determined whether or not the address extracted by (1) matches (display name match determination step). In the display name match determination step, if it is determined that the display name displayed in the e-mail destination display field and the address extracted by the address extraction unit 212 do not match, the warning notification unit 214 warns the user. Is notified (warning notification step). On the other hand, when it is determined that the display name displayed in the e-mail address display field matches the address extracted by the address extracting unit 212, a process of transmitting the e-mail is performed (mail transmission step).

  In the warning notification step, for example, a user who receives a warning by displaying a warning screen 115 as shown in FIG. 6 on the display unit determines the subsequent processing. For example, as in the first embodiment, it is possible to determine whether or not to send an e-mail by pressing the selection buttons 115a and 115b displayed on the warning screen 115 (confirmation step). The user presses the send button 115a when determining that the e-mail can be transmitted as it is, and presses the cancel button 115b when determining that the e-mail is not transmitted. When the send button 115a is pressed, an e-mail is sent to the mail sending server 220 via the mail sending unit 211 (mail sending step).

  On the other hand, when the cancel button 115b is pressed, the mail client terminal 110 performs processing for deleting an electronic mail (mail deletion step). Therefore, the electronic mail is not transmitted to the mail transmission server 220. In addition, when the cancel button 115b is pressed, the e-mail may not be deleted, and the mail transmission process may be interrupted so that the e-mail can be corrected.

  As described above, in the mail transmission system 100 according to the present embodiment, the mail transmission server 120 performs destination confirmation processing for preventing erroneous transmission of electronic mail.

  The mail transmission system 200 according to the second embodiment has been described above. According to the mail transmission system 200, whether or not there is an erroneous transmission of an email is determined by checking whether or not the destination in the body of the email matches the display name representing the transmission destination of the email. The Therefore, even if the user mistakenly selects the transmission destination of the electronic mail from the mail address storage unit 215, it is possible to reliably prevent erroneous transmission with such a simple configuration. In addition, since the mail client terminal 210 has a function of checking an erroneous mail transmission, for example, the display name associated with the mail address stored in the mail address storage unit 215 can be customized for each mail client terminal 210 by the user. Therefore, it is possible to more reliably prevent erroneous transmission by storing the address written in the text of the mail in the mail address storage unit 215 as the display name of the electronic mail.

The e-mail created by the user using the mail client terminal 310 is transmitted to the mail transmission server 320 connected to the mail client terminal 310 via the LAN 340, for example. The mail transmission server 320 can transmit and receive external computer information via the general-purpose network 330.

  The mail client terminal 310 is a terminal for creating an electronic mail. For example, the mail client terminal 310 includes a mail transmission unit 311, an address extraction unit 312, a display name match determination unit 313, a warning notification unit 314, and a mail creation unit 317. , An information acquisition unit 318. Further, for example, a display unit (not shown) such as a display for displaying information can be further provided. The mail client terminal 310 can be exemplified by a personal computer, for example. Further, the information acquisition unit 318 acquires information stored in the mail address storage unit 321 and the honorific storage unit 323 provided in the mail transmission server 320 to the mail client terminal 310 side. The information acquisition unit 318 accesses the mail transmission server 320 in response to an information acquisition request from the address extraction unit 312 or the display name match determination unit 313, and acquires information.

  The mail transmission server 320 is a server that performs mail transmission processing, and includes, for example, a mail address storage unit 321 and a title storage unit 323. The mail transmission server 320 performs processing for receiving the electronic mail transmitted from the mail client terminal 310 and transmitting it to the external mail client terminal via the general network 330.

  In the mail transmission system 300 configured as described above, the e-mail created at the mail client terminal 310 is confirmed at the mail client terminal 310 at the e-mail transmission destination. First, based on the information input by the user using the mail client terminal 310, an e-mail is created by the mail creating unit 317 (mail creating step). For example, information (for example, the contents shown in FIG. 2) stored in the mail address storage unit 321 of the mail transmission server 320 is displayed on the mail client terminal 310, and the user can send the electronic mail from the displayed information. This can be entered by selecting. When the user inputs an e-mail transmission destination, the display name stored in the e-mail address storage unit 321 is displayed in the destination display field of the e-mail header.

  Next, after the user creates an e-mail, for example, when an e-mail transmission instruction is performed by clicking a transmission icon, the mail client terminal 310 checks whether there is an error in the e-mail transmission destination. At this time, first, the address extracting unit 312 extracts the address, and determines whether or not the address is described in the body of the e-mail (address extracting step). Since the processing in the address extraction step is the same as that in step S105 of the first embodiment, detailed description thereof is omitted here. The title stored in the title storage unit 323 used when acquiring the address from the text of the e-mail is acquired by the information acquisition unit 318 and transmitted to the address extraction unit 312.

  When it is determined in the address extraction step that the address is described in the body of the e-mail, the display name match determination unit 313 extracts the display name displayed in the e-mail address display field and the address extraction unit 312. It is determined whether or not the received address matches (display name match determination step). In the display name match determination step, if it is determined that the display name displayed in the e-mail destination display field and the address extracted by the address extraction unit 312 do not match, the warning notification unit 314 warns the user. Is notified (warning notification step). On the other hand, if it is determined that the display name displayed in the e-mail address display field matches the address extracted by the address extracting unit 312, a process for transmitting the e-mail is performed (mail transmission step).

  In the warning notification step, for example, a user who receives a warning by displaying a warning screen 115 as shown in FIG. 6 on the display unit determines the subsequent processing. For example, as in the first embodiment, it is possible to determine whether or not to send an e-mail by pressing the selection buttons 115a and 115b displayed on the warning screen 115 (confirmation step). The user presses the send button 115a when determining that the e-mail can be transmitted as it is, and presses the cancel button 115b when determining that the e-mail is not transmitted. When the send button 115a is pressed, an e-mail is sent to the mail sending server 320 via the mail sending unit 311 (mail sending step).

  On the other hand, when the cancel button 115b is pressed, the mail client terminal 310 performs processing for deleting an electronic mail (mail deletion step). Therefore, the electronic mail is not transmitted to the mail transmission server 320. In addition, when the cancel button 115b is pressed, the e-mail may not be deleted, and the mail transmission process may be interrupted so that the e-mail can be corrected.

  As described above, in the mail transmission system 300 according to the present modification, the mail client terminal 310 performs destination confirmation processing for preventing erroneous transmission of electronic mail. At this time, the mail address storage unit 321 and the title storage unit 323 which are databases are provided in the mail transmission server 320. That is, the mail client terminal 310 is configured to access the mail transmission server 320 as necessary, such as acquisition of a display name associated with the mail address. For example, when it is desired to share a mail address stored in the mail address storage unit 321 or a title stored in the title storage unit 323, or when storing information related to a huge amount of mail addresses in the mail address storage unit 321, The mail address storage unit 321 and the title storage unit 323 are preferably provided in the mail transmission server 320.

  The mail transmission system 300 according to the modification of the first embodiment and the second embodiment has been described above. According to such a mail transmission system 300, whether or not there is an erroneous transmission of an e-mail is determined by checking whether or not the address in the body of the e-mail matches the display name representing the e-mail transmission destination. The Therefore, even when the user mistakenly selects the transmission destination of the electronic mail from the mail address storage unit 321, it is possible to reliably prevent erroneous transmission with such a simple configuration.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns.
