Description

Detailed Description of the Invention

[001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic mail transfer system, and more particularly to a system capable of reliably transferring an electronic mail sent to a recipient's previous address to the current address.

[002]

2. Description of the Related Art With the spread of the Internet, electronic mail has become more important as a daily communication means. When using this e-mail, the sender creates an e-mail using an e-mail dedicated program (hereinafter referred to as "mailer") set up on his or her personal computer, etc. ISP ”) mail server. The ISP's mail server receiving this checks the destination information of the email and transfers the email to the recipient's mail server. After that, the electronic mail is transferred from the router on the Internet to the router by the bucket brigade method, and reaches the mail server of the recipient.

The recipient connects to the mail server using the mailer set up on his or her personal computer, and occasionally checks whether or not a new electronic mail exists in the mailbox. If new mail exists, the mailer receives it from the mail server and stores it in the hard disk of the personal computer. As a result, the recipient can open the electronic mail on the mailer and browse the contents. In addition, a reply e-mail can be sent or transferred to a third party as it is, if necessary.

[004]

The address of an electronic mail is literally destination information, and in order to deliver the electronic mail to the receiver without fail, the sender accurately describes the address of the recipient in the destination field of the mailer. There is a need. However,
The e-mail address often changes due to the recipient's convenience. For example, when the subscription provider is changed, the mail address is inevitably changed to that of the newly subscribed provider. For the purpose of eliminating junk mail, the provider may change only the mail address as it is. Also, when changing jobs, the email address of the original company is changed to the email address of the new company. In such a case, a mail for notifying the address change is usually prepared by the user himself and sent to an acquaintance.

However, it goes without saying that creating a change notification mail and sending it to many people requires time and effort, but due to omission of notification, an important email is sent to the recipient's previous address. There was a risk that it would not have been reached. In addition, when sending e-mail, it is common to create a reply mail based on the previously received e-mail and send it as it is.In this case, even if you receive the change notification mail, the previous mail will be sent. It will be sent to the address.

Even if an e-mail is mistakenly sent to the previous address, at least the sender can recognize the fact that the mail has not been reached if the mail server sends a message indicating that there is no corresponding person. Such messages do not always arrive from the server. In this case, a trouble may occur between the sender who intended to send the electronic mail and the recipient who has not actually received the electronic mail. Further, even if a message indicating that the destination does not exist arrives, it takes time for the sender to inquire the new address of the destination. In particular, when the sender and the receiver are mainly in communication by e-mail, there is a case where the inquiry destination of the new address cannot be known.

The present invention was devised in order to solve the above-mentioned problems of the conventional electronic mail system, and when the recipient changes the electronic mail address, only the old address is recognized. It is an object of the present invention to provide a system capable of reliably transferring an electronic mail sent from an unsender to a new address and automatically notifying the sender of the new address.

(6) The management server 12 sends information to the effect that the recipient 20 has completed the user registration of the system 10 to the receiving-side pre-server 26. (7) The server 26 on the receiving side registers the user as a "transfer required user" in the predetermined database together with the old mail address.

Next, a mail transfer processing procedure according to the present system 10 will be described with reference to the sequence diagram of FIG. First, the sender 14 creates an e-mail using the mailer of the sending personal computer 16 (S10) and sends it to the old address of the recipient 20 (S11), and reaches the sending server 18 through the public network 28. To do. The transmission side server 18 transfers the electronic mail to the reception side front server 26 (S12).

Upon receiving this, the front server 26 on the receiving side confirms that there is no corresponding person at the mail address at present (S13), and transfers the electronic mail to the management server 12 (S14). The management server 12 searches the user database 34 to recognize the new address of the recipient 20 associated with the old address (S15), and transfers the electronic mail to the new address (S16). The receiving side current server 24 stores the electronic mail in the mailbox, waits until the receiving side personal computer 22 outputs the electronic mail delivery request, and delivers the electronic mail (S17).

On the other hand, the management server 12 is the receiving side current server 24.
After the e-mail is transferred to the e-mail, a notification e-mail having the following description contents is generated (S18) and sent to the e-mail address of the sender 14 displayed in the header of the e-mail (S19). (1) Successful transfer to the new address is completed (2) Recipient's 20 e-mail address is changed (3) New e-mail address This notice mail reaches the sending server 18 The mail is delivered to the sending personal computer 16 after waiting for a mail delivery request from the sender 14 (S20). As a result, from the next time onward, the sender 14 can correctly send an electronic mail to the current mail address of the recipient 20.

However, since the recipient may change the address for the purpose of evading the unwanted mail, instead of automatically sending the notification mail in which the new address of the recipient is described to the sender as described above. , When forwarding e-mail from the sender to the recipient, "Please notify the sender himself if you wish to receive the e-mail sent from the sender in the future. It is also possible to add a description to the effect such as “” to the electronic mail or to separately send an electronic mail to which the same effect is described. Alternatively, the notification email similar to the above may be sent to the sender's email address only when the recipient receives individual or comprehensive permission.

FIG. 3 is a flowchart showing in more detail the processing procedure in the reception side pre-server 26. That is, when the front server 26 on the receiving side receives the e-mail transferred from the server 18 on the sending side (S30), the server 26 on the receiving side refers to its own user database and confirms whether or not the person corresponding to the e-mail address exists. Yes (S31). Here, if the existence of the existing user can be confirmed, the electronic mail is stored in the mailbox as usual, and is delivered after waiting for a delivery request from the recipient (S32).

If the existence of the person concerned cannot be confirmed, it is checked whether or not the corresponding e-mail address belongs to the user requiring transfer (that is, the user of this system 10) by referring to the database for the user requiring transfer. (S33).
Here, if the user is not the transfer-required user, an out-of-office notification e-mail is generated to the sender's e-mail address stating that "there is no transmission because the person concerned does not exist" and is sent to the sending server 18. It is transmitted (S34). On the other hand, if the transfer required user registration is made, the electronic mail is transferred to the management server 12 (S35). After that, the processes of S15 to S20 in FIG. 2 described above are executed.

When the front server 26 on the receiving side determines that there is no person corresponding to the e-mail address, it is determined whether or not the user is a transfer-requiring user as described above, and only when the user is a transfer-requiring user. Instead of forwarding the e-mail to the management server 12, all the e-mails may be forwarded to the management server 12 when it is determined that there is no corresponding person. As a result, the front server 26 on the receiving side does not need to install a database relating to the transfer-required users, and the processing can be reduced. The management server 12 that has received the forwarded mail from the receiving-side front server 26 refers to the user database 34 held by itself, and if there is a user who has registered the e-mail address as the old address, Executes the processing of S16 to S19 in FIG. 2 described above. On the other hand, if the user does not exist, the management server 12 sends the absence notification mail to the sender of the electronic mail.

In the above description, when the receiving-side pre-server 26 determines that "there is no corresponding person" and "a transfer-requiring user", the electronic mail is mechanically transferred by the management server 12 to the receiving-side current server 24. Although it has been described on the premise that it is performed, the recipient may be given an opportunity to select whether or not to receive. In this case, as shown in the flow chart of FIG. 4, when the management server 12 receives the e-mail transferred from the receiving front server 26 (S40), the management ID is added to the e-mail and the e-mail is stored in a predetermined mailbox. Store (S41). Next, an inquiry e-mail having the following description contents is generated (S42), the user database 34 is referenced, and the inquiry e-mail is sent to the new mail address of the recipient 20 (S43). (1) Sender's e-mail address, title, date and time of transmission (2) Management ID of the e-mail (3) Access to the website within a certain period of time, and the intention of "receipt" or "receipt refusal" should be indicated (4) URL of the above website

Recipients who viewed this inquiry mail 20
After accessing the designated website and entering the management ID in the dedicated web page, selects whether to receive the e-mail. If the recipient selects "receive" (S46), the stored e-mail is transferred to the new mail address (S47). At the same time, similarly to the above, a notification mail stating that the transfer has been successfully completed and a new mail address is delivered to the sender 14 (S48). On the other hand, when the recipient 20 selects “rejection refusal”, a notification mail is generated that describes that the recipient 20 refused to receive the message and the content that warns the recipient to never send it again. , Is delivered to the sender (S48). As a result, it is possible to eliminate unwanted mail that the user does not want in advance. If the recipient 20 does not access the website within the preset period (S44), the stored e-mail itself is deleted from the mailbox (S45), and a notification mail to that effect is sent. It is transmitted to the sender 14 (S48).

In the transfer processing described above, the receiving front server 26 sends the e-mail addressed to the old address to the management server 12.
Is to execute the process of transferring to the
It is assumed that 26 cooperation will be obtained. However, even if the cooperation of the server 26 on the receiving side cannot be obtained, it is possible to transfer the electronic mail to the new mail address of the receiver 20. That is, as shown in the sequence diagram of FIG. 5, regarding the electronic mail generated and transmitted by the transmitting side personal computer 16 (S50, S51) and transferred from the transmitting side server 18 (S52), it is determined that there is no corresponding person. When the server 26 is judged (S53),
The server 26 on the receiving side generates an absent notice mail in which a message "Cannot be sent because the person is absent" is generated, and
It transmits to 14 (S54).

The sender 14 who has received the absence notification mail via the sender server 18 (S55) retransmits the original electronic mail to the management server 12 (S56). At this time, the address of the management server 12 is described in the destination field of the electronic mail, and the old address of the recipient 20 is described in the subject field or the like. The management server receiving this e-mail via the transmission side server 18 (S57) searches the user database 34 based on the old address described in the subject field, and recognizes the new address of the user (S58). Then, the electronic mail is transferred to the new address (S59). This e-mail is sent to the receiving personal computer 22 via the receiving current server 24.
(S60).

Further, the management server 12 generates a notification mail having the following description contents (S61) and sends it to the sender's mail address displayed in the header of the electronic mail (S62). . (1) Successful transfer to the new address is completed (2) E-mail address of the recipient has been changed (3) New e-mail address This notification e-mail reaches the sending server 18 The mail is delivered to the sending personal computer after waiting for the mail delivery request from the sender 14 (S63). As a result, from the next time onward, the sender 14 can correctly send an electronic mail to the current mail address of the recipient 20. However, instead of automatically sending a notification email containing the recipient's new address to the sender, as in the above, the recipient was asked "I would like to receive the email sent from the sender in the future. In such a case, it is also possible to operate so as to notify the sender of the change of address by himself. " Alternatively, the notification mail similar to the above may be sent to the sender's mail address only when permission is received from the receiver.

Also in this case, similarly to the above, the recipient 20 can be provided with an opportunity to select whether or not to receive the electronic mail. That is, as shown in the flowchart of FIG. 6, when the management server 12 receives the resend mail from the sender 14 (S70), the management ID is added to the e-mail and stored in a predetermined mailbox (S71). . Next, an inquiry e-mail having the following description contents is generated (S72), the user database 34 is referenced, and the inquiry e-mail is sent to the new mail address of the recipient 20 (S73). (1) Sender's e-mail address, title, date and time of transmission (2) Management ID of the e-mail (3) Access to the website within a certain period of time, and the intention of "receipt" or "receipt refusal" should be indicated (4) URL of the above website

Recipients who viewed this inquiry mail 20
After accessing the designated website and entering the management ID in the dedicated web page, selects whether to receive the e-mail. Here, if the recipient selects "receive" (S76), the stored e-mail is transferred to the new mail address (S77). At the same time, similarly to the above, a notification mail stating that the transfer has been successfully completed and a new mail address is delivered to the sender 14 (S78). On the other hand, when the recipient 20 selects “rejection refusal”, the sender 20 will receive a notification email stating that the recipient 20 has refused the receipt and that the recipient 20 will not be sent again. Will be delivered to (S7
8). As a result, it is possible to eliminate unwanted mail that the user does not want in advance. Also, if the recipient 20 does not access the website within the preset period (S74), the stored e-mail itself is deleted from the mailbox (S75), and a report mail to that effect is sent. It is transmitted to the sender 14 (S78).

[0034]

According to the electronic mail transfer system of the first aspect, even if the sender erroneously sends an electronic mail to the recipient's old address, the pre-reception-side server and management server The linking operation makes it possible to reliably transfer the e-mail to the recipient's new address.

According to the electronic mail transfer system of the fourth aspect, the sender directly resends the electronic mail to the management server even when the predecessor server and the management server cannot be linked. This makes it possible to reliably transfer the electronic mail addressed to the old address to the new address of the recipient.

According to the electronic mail transfer system described in claim 6, since the electronic mail in which the new address is described is automatically sent from the management server to the sender.
Even if the receiver does not bother to notify the sender, it can be expected to be correctly sent to the new address from the next time.
