Description

  The present invention relates to a communication device, a mail address confirmation processing method, and a mail address confirmation processing program for suppressing erroneous transmission of an electronic mail.

Today, there is a case where a desired partner is contacted by facsimile communication or electronic mail. However, erroneous transmission due to a mistake in the FAX number or e-mail address of the destination is a problem. Therefore, an information communication device and the like for preventing erroneous transmission when transmitting facsimile information or the like has been studied (for example, see Patent Document 1). The information communication device described in this document includes a destination address information storage unit that stores destination address information and an erroneous transmission address information storage unit that stores erroneous transmission address information. Then, the erroneous transmission discrimination means compares the set address of the transmission destination with the erroneous transmission address registered in the transmission destination address information storage means when the information communication device attempts to execute information transmission. Then, when the address of the transmission destination is registered in the erroneous transmission address information storage means, it is determined that the transmission is erroneous and notification is made.

  According to the present invention, it is possible to provide a communication device, a mail address confirmation processing method, and a mail address confirmation processing program for accurately and efficiently suppressing the erroneous transmission of broadcast mail.

  Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS. This embodiment will be described as a communication device, a mail address confirmation processing method, and a mail address confirmation processing program used when an employee transmits an electronic mail to a mail address (external address) outside the company.

  As shown in FIG. 1, a client terminal 10 is connected to a mail server 20 via a network. This mail server 20 functions as a communication device.

  The client terminal 10 is a computer terminal used by employees, and includes a control unit (CPU), a storage unit (RAM, ROM, etc.), a communication unit, and the like. The client terminal 10 stores a program related to mail software for sending and receiving e-mail, and by using these programs, e-mail transmission processing can be performed with a mail server described later.

  The mail server 20 connected to the client terminal 10 is a computer server used when an employee creates an e-mail. The mail server 20 includes a control unit 21. The control unit 21 includes a control unit (CPU), a storage unit (RAM, ROM, etc.), a communication unit, and the like. Each process in the output stage is performed). By executing the mail address confirmation processing program for this purpose, the control unit 21 functions as mail management means 21a and mail address confirmation processing means 21b as shown in FIG.

The mail management means 21a is a data storage means (transmission folder, send mail, draft mail) for each mail address used in the client terminal 10.
Receiving folder, draft folder). In the transmission folder, an e-mail received from the client terminal 10 is stored. The reception folder stores an electronic mail received at this mail address. The draft folder stores e-mails in the preparation stage before transmission, such as e-mails being created.

  Furthermore, the mail management means 21a holds data (local address book) related to the group address that is used when the electronic mail is broadcast. This local address book stores a group of mail addresses that are grouped in order to simultaneously send an electronic mail to a group address for specifying a group.

  On the other hand, the mail address confirmation processing means 21b executes an interrupt process when the mail management means 21a transmits an electronic mail. This mail address confirmation processing means 21 b includes an external address identification storage means comprising an in-house network address data storage unit 22 and a group company identification data storage unit 23.

  The in-house network address data storage unit 22 stores data related to the address of the in-house network in order to identify the e-mail address for external e-mail and the e-mail address for in-house e-mail. Specifically, since the determination is made using the domain name of the destination address, the domain name of the address of the in-house network is registered in the in-house network address data.

  The group company identification data storage unit 23 stores data relating to addresses of employees of group companies in order to identify e-mail addresses for e-mails not for group companies and e-mail addresses for e-mails for group companies. ing. Specifically, keywords included in the domain name of the group company are registered in the group company address data.

  Further, the mail address confirmation processing unit 21b functions as a check target address detection unit 211, an address memory 212, a group address processing unit 213, an in-house network address processing unit 214, a group company address processing unit 215, and an identical address detection processing unit 216. . Here, the group address processing means 213, the in-house network address processing means 214, and the group company address processing means 215 function as means for specifying an external address.

  The check target address detection unit 211 functions as a unit for specifying a transmission destination address, and executes a process for detecting a mail address that needs to be confirmed in a transmission destination address in an electronic mail to be broadcast. The check target address detecting unit 211 instructs each processing unit (213 to 216) to execute each processing described later.

  In the address memory 212, data relating to the mail address to be checked is recorded. Initially, the destination address specified in the e-mail for which transmission has been instructed is recorded. In the case of broadcast transmission, a plurality of mail addresses are recorded in the address memory 212.

  Further, the group address processing means 213 groups a plurality of mail addresses, and performs a development process for the group addresses used when an electronic mail is simultaneously transmitted to the mail addresses belonging to this group. Specifically, the group address processing unit 213 acquires information regarding the mail addresses belonging to this group from the local address book, and expands the group address into a specific mail address.

  The in-house network address processing means 214 detects an address using the in-house network among the e-mail transmission destination addresses, and performs a process of excluding it from the check target. In this case, data stored in the in-house network address data storage unit 22 is used.

  The group company address processing means 215 detects the mail address of the group company from the transmission destination address of the e-mail and performs a process of excluding it from the check target. In this case, data stored in the group company identification data storage unit 23 is used.

  Further, the same address detection processing means 216 compares the mail addresses to be checked finally remaining in the address memory 212 with each other, and counts the number of mail addresses of different destinations.

  Next, a processing procedure when an electronic mail is transmitted using the system configured as described above will be described. Here, it is assumed that an email is created using the email creation screen 500 (FIG. 4) displayed on the display of the client terminal 10.

  The control unit 21 of the mail server 20 executes an acquisition process for the email stored in the transmission folder (step S1-1). Specifically, when an e-mail transmission instruction is received from the client terminal 10 by selecting the send button on the e-mail creation screen 500, the e-mail management unit 21a stores the e-mail in the transmission folder. Then, the mail management means 21a makes a mail address check request to the mail address confirmation processing means 21b for the electronic mail for which the transmission instruction has been received. In this case, the check target address detection unit 211 acquires the transmission destination address from the electronic mail stored in the transmission folder. Specifically, the mail address recorded in the destination data field or CC data field of this e-mail is acquired. Then, the check target address detection unit 211 temporarily stores data regarding the transmission destination address in the address memory 212.

  Next, the control unit 21 of the mail server 20 executes an external mail address detection process (step S1-2).

  Here, first, the mail address confirmation processing means 21b executes a group address expansion process. Specifically, the group address processing unit 213 confirms whether or not the group address is included in the transmission destination address. When the group address is detected, the group address processing unit 213 acquires data related to the mail address constituting the group address from the local address book. Then, the group address processing unit 213 stores the acquired mail address in the address memory 212.

  Next, the mail address confirmation processing means 21b performs processing for excluding the in-house network address from the check target for the mail address stored in the address memory 212. Specifically, the in-house network address processing unit 214 collates the domain name of each mail address with the domain name recorded in the in-house network address data storage unit 22. Then, the mail address with the matching domain name is specified as the in-house network address, and this mail address is deleted from the address memory 212.

  Next, the mail address confirmation processing means 21b performs a process of excluding the address for the group company from the check target for the mail address stored in the address memory 212. Specifically, the group company address processing means 215 specifies a mail address including a keyword stored in the group company identification data storage unit 23 in the domain name of each mail address, and deletes this mail address from the address memory 212. To do.

  Next, the mail address confirmation processing means 21b calculates the number of transmission destinations outside the company group in this electronic mail. Specifically, the same address detection processing unit 216 compares the mail addresses to be checked remaining in the address memory 212 with each other, and counts the number of mail addresses (external mail addresses) of different destinations.

  Next, the control unit 21 of the mail server 20 executes a confirmation process as to whether or not two or more external mail addresses are included (step S1-3). Specifically, the mail address confirmation processing unit 21b acquires and determines the number of external mail addresses calculated by the same address detection processing unit 216.

  When two or more external mail addresses are included (in the case of “YES” in step S1-3), the control unit 21 of the mail server 20 executes a message output process (step S1-4). . Here, the mail address confirmation processing means 21 b transmits message data to the client terminal 10. As shown in FIG. 4, a warning message 510 is output on the mail creation screen 500 to the display of the client terminal 10 that has received this message data.

  In this case, the user selects a confirmation button on the warning message 510 when confirming the mail address. In this case, a transmission selection message 520 is output on the display of the client terminal 10. The transmission selection message 520 prompts the user to select whether to execute or cancel the transmission process.

  In this case, the user selects either the stop button or the transmission button on the transmission selection message 520. In this case, the client terminal 10 transmits either a stop instruction or a transmission instruction to the mail server 20 by this selection.

  When the mail server 20 receives a cancel instruction (in the case of “stop” in step S1-5), the control unit 21 executes this e-mail transfer process (step S1-6). Specifically, the mail address confirmation processing unit 21b moves the electronic mail stored in the transmission folder of the mail management unit 21a to the draft folder.

  On the other hand, when two or more external e-mail addresses are not included (in the case of “NO” in step S1-3), or when a transmission instruction is received (in the case of “transmission” in step S1-5), The control unit 21 of the mail server 20 executes transmission processing (step S1-7). Specifically, the mail address confirmation processing unit 21b notifies the mail management unit 21a of the check completion. The mail management unit 21a transmits an e-mail based on the check completion notification.

  As described above, according to the present embodiment, the following effects can be obtained.

  In the above embodiment, when two or more external mail addresses are included, the control unit 21 of the mail server 20 executes a warning message output process (step S1-4). Unlike a visual check, a mechanical check can reliably suppress erroneous transmission of broadcast mail.

In the above embodiment, when the group address is included in the transmission destination address, the group address processing unit 213 executes processing for expanding the group address into a mail address. Then, the expanded mail address is set as a check target. As a result, it is possible to check whether there is a problem with the group address, and it is possible to accurately suppress the erroneous transmission of the broadcast mail.

  In the above embodiment, the in-house network address processing means 214 detects an address that uses the in-house network among the e-mail transmission destination addresses, and performs a process of excluding it from the check target. From the point of view of personal information leakage, no problem arises if it is a person in the same organization. Therefore, it is possible to efficiently confirm by removing such a mail address and narrowing down the check target.

  In the above embodiment, the group company address processing means 215 detects the mail address of the group company in the e-mail transmission destination address, and performs the process of excluding it from the check target. Since there is no problem of leakage of personal information between group organizations (businesses), efficient e-mail addresses can be confirmed by removing such e-mail addresses and narrowing down the check targets.

  In the above embodiment, when the mail server 20 receives the cancel instruction, the control unit 21 moves the email stored in the transmission folder of the mail management unit 21a to the draft folder. As a result, the user can edit the mail address again and retransmit it efficiently.

  In addition, you may change the said embodiment into the following aspects.

  In the above embodiment, the mail address confirmation processing unit 21b executes an interrupt process when sending an email in the mail management unit 21a. In this case, it is possible to provide means for controlling the interruption of the e-mail check process. Thereby, operation according to the needs and management of each user company can be implemented.

  In the above embodiment, the in-house network address data storage unit 22 stores data related to the address of the in-house network in order to identify the outside mail address and the in-house email address. ing. The group company identification data storage unit 23 stores data relating to addresses of employees of group companies in order to identify e-mail addresses for e-mails not for group companies and e-mail addresses for e-mails for group companies. ing. Narrowing down the check target is not limited to the internal network address or group company address. It is also possible to provide a setting means that allows the user to flexibly set domain names and keywords to be excluded from the check target. Thereby, operation according to the needs and management of each user company can be implemented.

  In the above embodiment, the domain name of the address of the internal network is registered in the internal network address data recorded in the internal network address data storage unit 22. Then, using this domain name, the e-mail address of the external e-mail and the e-mail address of the in-house e-mail are identified. This identification method is not limited to this, and an IP address can also be used. In this case, the internal network address data storage unit 22 stores IP address data related to the internal network address.

  In the embodiment described above, the mail server 20 performs the mail address check process (each process of specifying the destination address, specifying the external address, outputting the warning message, etc.). Instead, this check process can be executed in the client terminal 10. In this case, the mail address confirmation processing means 21b is provided in the client terminal 10.
