Description

  The present invention relates to an e-mail transfer technique.

  Conventionally, in an electronic mail system, a transfer service for transferring received electronic mail to a predetermined address has been provided. In order to use this service, the user registers a forwarding address for his / her receiving address in the mail server.

  Then, when an e-mail is received at the receiving address, the mail server transfers the e-mail to the transfer destination. As a result, when changing the e-mail address, the user can use both the addresses before and after the change, or transfer the e-mail address used at work to the e-mail address used at home.

  Thus, the e-mail transfer function / transfer service has been convenient. However, it has been difficult to confirm from the address information only whether the transfer destination address is correct. Conventionally, in order to investigate the validity of a transfer destination address, for example, there is no choice but to determine whether it is in a previously registered list.

  In addition, when a delivery error occurs when transferring from an intranet to an external mail address, corporate secrets may be leaked. However, it has been difficult to prevent erroneous delivery by the conventional method of checking the list.

  Further, when the mail address changes, the legitimacy of the mail address cannot be determined by the method of referring to the registered address list. In addition, once the transfer destination address is registered, even if the address becomes invalid thereafter, illegal transfer may continue to be performed.

Including.

  These user terminals 3 and each server constitute an intranet by a local area network (hereinafter referred to as LAN). This intranet is connected to an external mail server on the Internet through an external gateway.

  The user terminal 3 is, for example, a personal computer (abbreviated as a personal computer). The user terminal 3 provides the user with functions such as access to a web server, access to the Internet, creation of mail, transmission, reception, and display. FIG. In 1, the user terminal 3 is given a mail address user@ff.co.jp.

The outgoing mail server 4 is a so-called server device, and has a CPU, a memory, a hard disk, a LAN board, etc. (not shown). The outgoing mail server 4 is connected to the LAN by a LAN board and manages the transmission of electronic mail (the LAN board corresponds to a communication unit).

The electronic mail to be transmitted is delivered from the user terminal 3 to the transmission mail server 4 via the LAN by smtp (Simple Mail Transfer Protocol) and relayed to the destination mail server. FIG. In 1, the outgoing mail server 4 is given a domain name of smtp.ff.co.jp.

    The received mail server 2 is also a so-called server device, and has a CPU, a memory, a hard disk, a LAN board, etc. (not shown). The received mail server 2 is connected to the LAN by a LAN board and manages reception of electronic mail (the LAN board corresponds to a communication unit).

The received electronic mail is read out to the user terminal 3 by pop (Post Office Protocol) via the LAN. FIG. In 1, the received mail server 2 is given a domain name of pop.ff.co.jp.

  The received mail server 2 provides a mail transfer function for transferring mail that has arrived to the user to another mail address designated by the user (the CPU of the received mail server 2 that provides this function corresponds to a transfer control unit). .

  For this reason, the received mail server 2 has a transfer checklist 5 for files in a hard disk (not shown). The transfer check list 5 is a file that defines a pair of an e-mail reception address and an e-mail transfer destination address received at the reception address.

  The received mail server 2 receives a reply to the test mail to the forwarding address from the user terminal 3 (the CPU and the LAN board of the received mail server 2 providing this function correspond to the receiving unit). The incoming mail server 2 determines the validity of the reply, and stores the forwarding address determined to be valid in the forwarding checklist 5 (the CPU of the incoming mail server 2 that provides this function). Corresponds to the confirmation part).

The web server 1 is also a so-called server device, and has a CPU, a memory, a hard disk, a LAN board, etc. (not shown).

Further, the web server 1 transmits a test mail for confirming the validity of the forwarding mail address set in such a web page (sent by the CPU and the LAN board of the web server 1 that provides this function). Part)). Furthermore, the web server 1 provides the user with information indicating a response procedure for responding to such a test mail. This information is described in html (hypertext markup language) and stored in a hard disk (not shown) (the CPU and hard disk of the web server 1 that executes this processing correspond to the information providing unit).

<Functional overview>
In the present invention, the forwarding address is set on the web page of the web server 1. When an application is made for a forwarding address that allows unconditional forwarding (for example, a mail address in the same department), the web server 1 immediately enables the forwarding of an electronic mail to the forwarding address. Therefore, such a forwarding address is notified from the web server 1 to the received mail server 2.

  When the user inputs a forwarding address that does not permit unconditional forwarding, for example, an external address, the web server 1 sends a test mail including a predetermined keyword (hereinafter referred to as keyword 2) to the forwarding address. To do.

  Details of the method of replying to the test mail are described on a web page provided by the same web server 1. If the reply to the specific address satisfies a predetermined requirement, the received mail server 2 recognizes the forwarding address as valid. The received mail server 2 validates the forwarding address and registers it in the forwarding check list 5. As a result, the received mail server 2 permits transfer to the transfer destination address.

Here, the predetermined requirement is that the reply is a call from a predetermined email address (in-house email address, etc.), and that the reply is described in a fixed form displayed on a web page. The case where the keyword 1 posted on the web page and the keyword 2 described in the test mail are included in the reply. If the reply content does not satisfy this condition, transfer to that address is not permitted.

  The incoming mail server 2 sets an expiration date for a valid forwarding address, and automatically sends a test mail again after a certain period. If the reply to the test email meets the predetermined requirements, the expiration date is extended.

  However, when there is no reply within a certain period, or when the reply does not satisfy a predetermined requirement, the received mail server 2 deletes the forwarding address from the forwarding check list 5. As a result, transfer to the transfer destination address is prohibited.

<Screen configuration>
FIG. 2 to FIG. 4 shows a setting screen that the web server 1 provides to the user terminal 3 via http (the CPU of the web server 1 that provides this function corresponds to a reception unit). These screens are provided from the web server 1 to the user terminal 3 in the intranet.

  Therefore, this screen cannot be accessed from a host (third party) on the Internet. FIG. 2 shows a setting screen used for setting the forwarding of the received mail to the company or the affiliated company.

  This screen includes a mail server designation field 11, a mail address designation field 12, a password designation field 13, a transfer destination address designation field 14 and a transfer designation to transfer source field 15, a “set” button, and a “cancel” button. Have.

In the mail address designation column 12, the received mail address of the user is designated. This is also called a transfer source address. This email address specification field 12 has a domain @ ff.co.jp
Specify a user account (user in FIG. 2) excluding.

  In the password designation column 13, a password for accessing the received mail server 2 from the user terminal 3 is designated.

  The transfer destination address designation field 14 designates a transfer destination address to which the electronic mail received at the transfer source address is transferred. However, FIG. In the setting screen of 2, only designation to transfer to the company or the affiliated company is allowed. When a check mark is entered in the transfer designation field 15 to the transfer source, the transfer source itself is included in the transfer destination address.

  After the above settings, when the user presses the “set” button on the user terminal 3 with a pointing device (not shown), the setting on this screen is changed to FIG. 1 is set in the transfer destination check list 5 shown in FIG. When the cancel button is pressed, FIG. The setting of the second screen is discarded.

  FIG. 3 shows a display screen of transfer setting contents. This screen is used when displaying the setting contents of the transfer destination address. This screen is also shown in FIG. Similarly to the setting screen 2, the mail server designation field 11, the mail address designation field 12, and the password designation field 13 are provided. This screen also has a “display” button and a cancel button.

  In the mail server designation field 11, the domain name of the mail server that holds the transfer setting contents is designated. In the mail address specification column 12, a transfer source mail address is specified. In addition, the password designation field 13 includes FIG. As in the case of 2, the password is specified when the user terminal 3 accesses the mail server.

  After the above settings, when the user presses the “display” button, the setting contents of the transfer destination address for the transfer source address specified in the mail address specification column 12 are displayed. When the user presses the “Cancel” button, FIG. The setting contents of 3 are discarded.

  FIG. Reference numeral 4 denotes a display screen showing a procedure for setting the transfer of received mail to outside the company.

  This screen has an explanation display field 16 and a test mail sending field 17. The explanation display column 16 shows a test mail transmission request procedure for confirming the validity of the transfer destination and a procedure for responding to the test mail.

  After reading the explanation in the explanation display field 16, the user requests the test mail transmission field 17 to send a test mail. The test mail sending field 17 has a mail server designation field 11, an in-house mail address designation field 12A, a forwarding address designation field 14A, a “Send” button, and a “Cancel” button.

  In the mail server designation field 11, FIG. As in the case of 2, the domain name of the received mail server 2 is designated. In the in-house mail address designation column 12A, FIG. As in the case of the email address designation field 12 in FIG. 2, the forwarding email address is designated. In addition, a mail address of an external forwarding destination is designated in the forwarding destination mail address designation column 14A.

  After such setting, when the user presses the “Send” button, the web server 1 transfers the in-house e-mail address specified in the in-house e-mail address specification column 12A and the transfer specified in the transfer destination e-mail address specification column 14A. Send a test email to the destination address.

  At the same time, a fixed phrase C that is designated in the mail server designation field 11 and requests transfer permission from the web server 1 is transmitted from the web server 1 (the CPU of the web server 1 that executes this process sends a command to the command unit). Equivalent to).

  When the fixed sentence C is received, the incoming mail server 2 sets the forwarding address to FIG. 1 is added to the transfer destination checklist 5 shown in FIG. However, in this case, the forwarding address is set to a waiting state for confirmation, and the received mail is not actually forwarded to that address.

  When the user receives the test mail at the in-house electronic mail address and the forwarding address, the user transmits a response to each test mail according to the procedure in the explanation display field 16. When the mail server receives the two responses and the validity of the responses is confirmed, the received mail server 2 sets the forwarding address that has been set to wait for confirmation in the forwarding destination checklist 5 to the forwarding-permitted state. To do. As a result, the forwarding address becomes valid, and the received mail is forwarded to the forwarding address.

<Data structure>
FIG. 5 shows an example of a test mail transmitted from the web server 1 to an external forwarding address zzz@xxx.com. This test mail has a title and a text.

In the test mail, the title is set to mail test, for example. In the body, a keyword 2 including a random number and a forwarding address expiration date 20010320 (March 20, 2001) are described.

  An e-mail having the same content as the test e-mail is also sent to a normal in-house e-mail address (an e-mail address designated in the in-house e-mail address designation field 12A of FIG. 4).

  FIG. 6 shows an example of a fixed phrase C transmitted from the web server 1 to the reception address fwcheck@ff.co.jp of the received mail server 2. This email is called a transfer permission request email. The transfer permission request mail has a title, a sender, and a text.

The subject is set to forward check in the forward permission request mail. The sender's e-mail address of the user who uses the transfer function is described in the sender. In the text, for example, a character string “forward check list”, an email address of a user who uses the forwarding function, an email address of the forwarding destination, a keyword 2 composed of random numbers, a forwarding destination address expiration date, and a reply valid The deadline is described.

  Here, the transfer destination address expiration date is the expiration date of the transfer destination address set by the user within a predetermined allowable range. On the other hand, the reply valid period is a reply valid period set by the system parameter in the web server 1. If the user replies to the test mail after this reply expiration date, forwarding is not permitted.

FIG. FIG. 7 shows an example of a response mail that the user transmits from the electronic mail address user@ff.co.jp to the response reception address forward-append@ff.co.jp of the received mail server 2.

When the user receives a test mail at a normal in-house e-mail address (an e-mail address specified in the in-house e-mail address specification field 12A of FIG. 4) and a forwarding address, a response mail to the test e-mail is received by the receiving mail server. Send to 2 reception address forward-append@ff.co.jp. FIG. 7 shows an example of a response that the user transmits from a normal in-house e-mail address.

This response mail has a title, text, name, affiliation, transfer destination, transfer reason, keyword 1, keyword 2, and expiration date. The structure of such a response mail is the web server 1
Specified on the procedure screen (FIG. 4) for setting up forwarding outside the company.

In this response mail, the title is set to forward-append@ff.co.jp. In the text, "Please allow transfer settings." The name and affiliation are the name and department of the user who registered the forwarding address. The transfer destination is an external transfer destination mail address to which the received mail is transferred.

  The keyword 1 is specified on the procedure screen (FIG. 4) of the transfer setting to the outside provided by the web server 1. The keyword 2 is specified in the text of the test mail transmitted from the web server 1 to the forwarding address. The transfer destination address expiration date is an expiration date for which transfer of electronic mail is permitted.

  FIG. 8 shows an example of data in the transfer check list 5 that the received mail server 2 has. This transfer check list 5 is set for each user who receives the service of the received mail server 2. In the transfer checklist 5, the user name is specified on the first line. In addition, transfer destination designation is listed below the second row.

  Each transfer destination designation line includes a transfer destination address, a status, a keyword 2 and a transfer expiration date. In each line, the characters after the “#” character are comments. Among these, the state defines the use state of each transfer destination address.

  For example, when the status is OK, it indicates that an e-mail transfer service to the transfer destination address is being performed.

  When the status is WT, the received mail server 2 receives the transfer permission request mail from the web server 1, and indicates that the transfer destination address is being confirmed by the test mail. Alternatively, when the status is WT, the expiration date of the forwarding address has passed, and the forwarding address may be being confirmed by a test mail.

  In the case of NG, this indicates that the transfer destination address cannot be used. This is a transfer destination address designated by the user to stop using a user interface (not shown). As described above, the user can select and use a desired one of the plurality of transfer destination addresses registered in the transfer check list 5 and stop others.

For example, FIG. In the second line of the transfer check list 5 shown in FIG. 8, the transfer destination address xxx@nif.com is designated and the state is OK. Therefore, the e-mail currently delivered to user is forwarded to xxx@nif.com. The expiration date of this forwarding address is set on February 28, 2001.

In the third line, the transfer destination address yyy@ppp.com is designated and the state is NG. Therefore, currently received electronic mail is not forwarded to this forwarding address.

In the fourth line, the forwarding address zzz@xxx.com is specified and the status is WT, that is,
Waiting for confirmation. Therefore, when a response mail to the test mail corresponding to this forwarding address is normally received, this forwarding address is used.

<Action and effect>
FIG. 9 shows a procedure for setting a forwarding address in the electronic mail management system. Now, according to the user operation, the web page of the web server 1 is displayed on the user terminal 3.

  The user terminal 3 receives input of the user's name, e-mail address, forwarding address, etc. on this web page. This input is transmitted to the web server 1 via the LAN (arrow 101).

  If the forwarding address is within the permitted range, the web server 1 immediately sends a setting file describing the forwarding address to the incoming mail server 2. Here, the setting file is a file that describes the name of the user who requested the transfer setting, the transfer destination address, and the transfer destination address expiration date.

  On the other hand, if the forwarding address is out of the permitted range, the web server 1 transmits a test mail A in which the keyword 2 is specified as the forwarding address. Further, the web server 1 transmits a test mail B in which the keyword 2 is designated as a normal received mail address (forwarding mail address). Further, the web server 1 embeds the forwarding destination information of the user in the format of the fixed phrase C and transfers it to the received mail server 2 (arrow 102).

  This fixed sentence C includes the user's normal use mail address, transfer destination address, keyword 2, transfer destination address expiration date, and reply expiration date. The received mail server 2 stores the transfer destination information of the user in the temporary file 7.

  Then, the test mail A transmitted above is received by the user terminal 3 from the forwarding mail address (arrow 103). Further, the test mail B is received by the user terminal 3 from a normal received mail address (arrow 104). Note that the terminals receiving the test mails A and B may not be the same terminal.

  The user terminal 3 displays a reply procedure for the web page and a reply example sentence D (arrow 105), and the user refers to the reply procedure and the reply example sentence D. Further, in this reply procedure, keyword 1 is specified (see FIG. 4). The user creates a reply mail X for the test mail A by adding the name, affiliation, keyword 1 and the like to the contents of the received test mail A with reference to the reply example sentence D. Further, the user adds a name, affiliation, keyword 1 and the like to the content of the received test mail B with reference to the reply example sentence D, and creates a reply mail Y for the test mail B.

  Then, the user transmits the reply mail X and reply mail Y to the received mail server 2 with the titles specified in the standard text from the normal mail address (transfer source address) and the transfer destination address (arrow 106).

  The received mail server 2 confirms whether the reply mails X and Y are received within the reply valid period. When the reply mails X and Y are received within the reply validity period, the received mail server 2 confirms whether or not the keyword 1 is included in the reply mails X and Y. The keyword 1 is information set as a constant in the web server 1 and the incoming mail server 2.

  If the keyword 1 is included in these reply mails, the received mail server 2 can confirm that the reply mails are in accordance with the procedure for setting forwarding outside the company (FIG. 4). Therefore, next, the received mail server 2 collates the reply mails X and Y with the fixed phrase C.

  Then, if the reply mail X (including keyword 2) and Y (including keyword 2) are consistent with the contents of the fixed phrase C (including keyword 2), the received mail server 2 adds the transfer check list 5 to the transfer check list 5. A transfer destination address is added in an OK state.

  At the same time, the received mail server 2 sets the expiration date of the transfer destination address in the transfer destination check list 5. Then, the received mail server 2 deletes the fixed phrase held in the temporary file 7.

  On the other hand, when the keyword 1 is not included in the reply mail X or Y as described above, it is determined that these reply mails are not valid replies according to the procedure for setting forwarding to outside the company (FIG. 4).

  Further, even if the keyword 1 is included in these reply mails X or Y, if these reply mails X or Y do not match the contents of the fixed phrase C (for example, when the keyword 2 is not included), The received mail server 2 determines that the reply mail is not a valid reply mail.

  In these cases, the incoming mail server 2 does not set a forwarding address in the forwarding destination check list 5. Then, the received mail server 2 deletes the fixed phrase held in the temporary file 7.

  FIG. 10 shows an expiration date confirmation process executed by the received mail server 2. This process is periodically started in the incoming mail server 2 and executes the expiration date management of the forwarding address.

  In this process, first, the received mail server 2 reads the next transfer destination designation line whose status is designated as OK from the transfer check list 5 (S1). Then, the received mail server 2 determines whether or not the transfer expiration date included in the transfer destination designation line is a predetermined date before the expiration (S2).

  If the transfer expiration date is a predetermined date before the expiration date, the received mail server 2 sends a test mail to the transfer destination (S3). Thereafter, the received mail server 2 advances the control to the determination of S6. The response to this test mail is shown in FIG. Processing is performed in the same procedure as described in 9.

  On the other hand, if it is determined in S2 that it is not before the predetermined expiration date, the received mail server 2 determines whether or not it has expired based on whether or not the transfer expiration date has passed the current date (S4). When the expiration date has expired, the received mail server 2 deletes the forwarding destination designation line from the forwarding check list 5.

  Thereby, the received mail server 2 stops the transfer service for the transfer destination address (S5). Thereafter, the received mail server 2 advances the control to the determination of S6. If the expiration date is not expired in the determination in S4, the received mail server 2 skips the forwarding destination designation line and advances the control to the determination in S6.

  Next, the received mail server 2 determines whether or not there is a next transfer destination designation line in the transfer check list 5 (S6). If there is a next transfer destination designation line, the received mail server 2 returns the control to S1. On the other hand, if there is no next transfer destination designation line, the received mail server 2 ends the process.

  As described above, in this electronic mail management system, the validity of the forwarding address is confirmed in the electronic mail transfer function in the received mail server 2. That is, when a test mail is transmitted to the forwarding address and a valid reply mail is returned to the receiving mail server 2 for the test mail, the forwarding address becomes valid. Therefore, it is possible to prevent an incorrect forwarding destination from being set by processing of the received mail server 2.

  Further, the received mail server 2 confirms not only a response from the forwarding address for the test mail but also a response to the test mail from a normally used mail address as a validity condition. Therefore, it is possible to respond to the test mail using a pre-managed e-mail address. For this reason, an illegal response to the test mail can be prevented.

  Further, the web server 1 of the above embodiment immediately receives the incoming mail server 2 if the forwarding address requested for forwarding setting on the web page is within a predetermined range, for example, the address range of a company or an affiliated company. To register. On the other hand, a test mail is sent to the forwarding address outside the company. For this reason, the forwarding address within the company can be quickly registered. On the other hand, it is possible to strictly check the forwarding destination of e-mail outside the company.

  The received mail server 2 has a transfer destination address expiration date in each transfer destination designation line of the transfer check list 5. For this reason, it is possible to prevent the e-mail from being transferred to the transfer destination address indefinitely. Further, the validity or invalidity of the transfer can be freely set within such a time limit.

  In the present embodiment, a response procedure for the test mail is provided from the web server 1 on the intranet. Therefore, it is possible to prevent an external third party from responding to the test mail by impersonation.

<Modification>
In the above embodiment, the test mail A is transmitted to the transfer destination address, and the test mail B is transmitted to the normally used transfer source mail address. However, the implementation of the present invention is not limited to such a configuration and procedure. For example, it is not necessary to send the test mail A to the forwarding address and send the test mail B to the usual forwarding mail address. That is, the validity of the transfer destination address may be confirmed only by a test mail addressed to the transfer destination address.

  In the above embodiment, the web server 1 that provides a web page that receives an application for a forwarding address has transmitted a test mail to the forwarding address 2. In addition, the web server 1 transmits a fixed phrase C for requesting transfer permission to the incoming mail server 2. However, the implementation of the present invention is not limited to such a configuration and procedure.

For example, the web server 1 may request another communication device to send a test mail. Further, the web server 1 may send a fixed sentence C for requesting transfer permission to the received mail server 2 and may request the received mail server 2 to send a test mail (in this case, the received mail server 2 communicates). Corresponds to the device). At this time, the communication between the web server 1 and the incoming mail server 2 may be performed by e-mail, or other file transfer functions such as ftp (file transfer protocol), files by nfs (network file system), etc. A sharing function may be used.

  In that case, FIG. In the configuration of 1, the incoming mail server 2 and the outgoing mail server 4 may operate on the same host. Further, the web server 1 and the received mail server 2 may operate on the same host. In that case, the received mail server 2 may perform reception of a transfer setting request, transmission of a test mail, confirmation of a response to the test mail, registration of a transfer destination address after confirmation of the response, and the like.

Conversely, different server devices may be assigned to receive transfer setting requests, send test mails, confirm responses to test mails, register transfer destination addresses after confirming responses, and the like. Communication between the servers in this case is the above-mentioned e-mail, ftp, nfs, or DCOM (Distributed Component Object) provided as a function of Windows, which is a well-known remote procedure call in the unix system, or Microsoft's OS. Model) may be used.

  In the above embodiment, the keyword 1 is fixedly set as a constant value in the web server 1 and the incoming mail server 2. However, instead of this, the keyword 1 may be delivered from the web server 1 to the received mail server 2. For this purpose, the keyword 1 may be included in the fixed phrase C (FIG. 6) transmitted from the web server 1 to the received mail server 2.

<< Second Embodiment >>

  Then, when the response to the test mail is confirmed in the same procedure as in the first embodiment, the forwarding address is added to the forwarding permission list 6 and further registered in the forwarding setting file 8. . The transfer setting request is held in the temporary file 7 until the response to the test mail is confirmed.

<Data structure>
FIG. 12 is an example of an e-mail transmitted from the user terminal 3 to the received mail server 2 when a transfer setting request is made. A user who wishes to transfer the received e-mail receives the FIG. Address to the reception address of the receiving mail server 2 (fwset@ff.co.jp in FIG. 12). The e-mail shown in FIG.

FIG. In the 12 e-mails, the title “forward-set” indicates that this e-mail is a forwarding setting request. In addition, “set forward list” described in the first line of the text indicates that forwarding destination addresses are listed below that line. However, the implementation of the present invention is not limited to such a title or description of the text itself.

In addition, FIG. In 12 e-mails, aaa@ff.co.jp is a forwarding address. In addition, FIG. The last line \ user of 12 is a designation for registering the transfer source address itself as the transfer destination.

  FIG. FIG. 13 shows an example of the transfer permission list 6. The transfer permission list 6 is created for each user. In the first line of the transfer permission list 6, the name of the user who is the recipient of the electronic mail to be transferred is described.

  The transfer permission list 6 lists the permitted transfer destination addresses and the expiration date of the permission after the description of the user name. For example, *@ff.co.jp is a specification that permits all internal transfers. That is, transfer to all addresses of the domain name ff.co.jp is permitted. FIG. In 13, an indefinite period is set for an in-house address.

In addition, FIG. 13, for example, “bbb@nif.com 20010630” indicates that transfer to the transfer destination address bbb@nif.com is permitted until June 30, 2001. FIG. 14 shows an example of an e-mail transmitted from the received mail server 2 to the user terminal 3 when the transfer setting request is approved and the transfer destination address is registered in the transfer setting file 8. Note that when the transfer setting request is not approved, the received mail server 2 may notify the user terminal 3 accordingly. The CPU of the received mail server 2 that executes such processing corresponds to the notification unit.

This e-mail indicates that the transfer setting request has been approved and the transfer destination has been changed by the title “forward-changed”. This text includes the registration completion date and time of the transfer destination, a message indicating that the transfer destination has been changed, and the setting contents of the transfer setting file 8 of the user after the change.

  FIG. 15 shows an example of an e-mail sent by the user in order to obtain the setting contents of the current transfer setting file 8. FIG. When the e-mail shown in FIG. 15 is transmitted to the received mail server 2, the received mail server 2 returns the setting of the transfer setting file 8 for the user.

In this e-mail, the title is “forward-get”, which indicates that the request is a reply to the setting contents of the transfer setting file 8. In addition, “get-forward-list” in the text indicates that this e-mail is a reply request for the setting contents of the transfer setting file 8. The target user is specified next to the “get-forward-list” line.

<Action and effect>
FIG. FIG. 16 shows a flowchart of the transfer setting process executed by the received mail server 2.
This process is started when an e-mail addressed to the reception address of the received mail server 2 (fwset@ff.co.jp in FIG. 11) is received. In this process, the received mail server 2 first reads the transfer setting request e-mail (S11).

  Next, the contents of the e-mail are stored in the temporary file 7 (S12). Next, the received mail server 2 executes a transfer permission list confirmation process (S13).

  FIG. 17 shows details of the transfer permission list confirmation process. In this process, the received mail server 2 first reads the next transfer destination from the temporary file 7 (S21). Next, the received mail server 2 confirms the transfer permission list 6 (S22). Then, it is determined whether or not the transfer destination address is included in the transfer permission list 6 (S23).

  If the transfer destination is included in the transfer permission list 6, the received mail server 2 moves the transfer destination from the temporary file 7 to the transfer setting file 8 (S24). Thereafter, the received mail server 2 advances the control to the process of S26.

  On the other hand, if the transfer destination is not included in the transfer permission list 6, the received mail server 2 transmits a test mail to the transfer destination (S25). When the response to the test mail is confirmed, the transfer destination is registered in the transfer permission list 6 and further set in the transfer setting file 8. Since the procedure for confirming the response to the test mail is the same as that in the first embodiment, the description thereof is omitted.

  Next, the received mail server 2 determines whether or not the temporary file 7 has the next transfer destination (S26). If the next transfer destination remains in the temporary file 7, the received mail server 2 returns the control to S21. On the other hand, if the next transfer destination does not remain in the temporary file 7, the received mail server 2 transmits a change notification mail to the user (S27). Thereafter, the CPU 2 ends the process.

  As described above, according to this embodiment, unlike the case of the first embodiment, transfer settings can be managed only by sending and receiving e-mails without using the web server 1.

<Computer-readable recording medium>
The program executed in the web server 1 or the incoming mail server 2 in the above embodiment can be recorded on a computer-readable recording medium. Then, by causing the computer to read and execute the program of the recording medium, the computer can function as the web server 1 or the incoming mail server 2 described in the above embodiment.

  Here, the computer-readable recording medium refers to a recording medium in which information such as data and programs is accumulated by electrical, magnetic, optical, mechanical, or chemical action and can be read from a computer. Examples of such a recording medium that can be removed from the computer include a floppy disk, a magneto-optical disk, a CD-ROM, a CD-R / W, a DVD, a DAT, an 8 mm tape, and a memory card.

  Further, there are a hard disk, a ROM (read only memory), and the like as a recording medium fixed to the computer.
