Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mail transfer system.
[0002]
[Prior art]
With the development of the Internet, e-mail addresses are known to third parties and unnecessary e-mails are increasingly sent. In order to prevent this unnecessary e-mail from being sent, it is effective not to input the e-mail address of one's e-mail on, for example, a web page of an information provider. However, this makes it impossible to receive information from an information provider by e-mail. Therefore, it is conceivable that a virtual mail address is set, the information provider is notified of the virtual mail address, and the information is transmitted to the virtual mail address. When the information provider sends an e-mail to a virtual mail address, a mail server corresponding to the virtual mail address transfers the e-mail to the actual mail address (see, for example, Patent Document 1). .
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 11-341045
[Problems to be solved by the invention]
By the way, although electronic mail is a bidirectional information transmission means, the technique described in Patent Document 1 does not provide for a case where a user who sets a virtual mail address returns an electronic mail.
[0005]
Therefore, an object of the present invention is to provide a mail transfer system that can send and receive electronic mail without knowing a mail address.
[0006]
[Means for Solving the Problems]
The mail transfer system of the present invention includes an address information storage means for storing a first mail address corresponding to the first information communication terminal and a first substitute mail address corresponding to the first mail address, Mail receiving means for receiving an e-mail transmitted from the second information communication terminal to the first substitute e-mail address, and rewriting the destination of the received e-mail from the first substitute e-mail address to the first e-mail address And an address rewriting means for rewriting the source of the received electronic mail from a second mail address corresponding to the second information communication terminal to a second substitute mail address corresponding to the second mail address, and the rewriting Mail sending means for sending the received e-mail to the first information communication terminal, and the mail receiving means sends the mail The reply e-mail to the e-mail sent by Dan is received, and the address rewriting means rewrites the destination of the received reply e-mail from the second substitute e-mail address to the second e-mail address, and the received reply e-mail The mail transmission source is rewritten from the first mail address to the first substitute mail address, and the mail transmission means transmits the rewritten reply electronic mail to the second information communication terminal.
[0007]
According to the mail transfer system of the present invention, the destination of the e-mail transmitted from the second information communication terminal to the first substitute mail address is rewritten to the first mail address corresponding to the first substitute mail address. For example, a user using the first information communication terminal sends information without disclosing the first mail address to the information provider using the second information communication terminal. Can receive. In addition, since the source of the forwarded e-mail is rewritten to the second substitute e-mail address corresponding to the second e-mail address corresponding to the second information communication terminal, the first information for receiving the e-mail Even if the user of the communication terminal performs a normal reply operation, the reply e-mail is not directly sent to the second information communication terminal, and the first e-mail address may be inadvertently sent. Is reduced. Further, the reply email address is rewritten from the second substitute email address to the second email address, the reply email sender is rewritten from the first email address to the first substitute email address, and the reply email is sent. Since the data is transmitted to the second information communication terminal, bidirectional information communication using the first substitute mail address is possible.
[0008]
In the mail transfer system of the present invention, the address information storage means stores the transfer upper limit number in association with the first mail address and the first substitute mail address, and the address rewriting means has the transfer upper limit number of times a predetermined number. The first e-mail address or the first substitute e-mail address is rewritten when the number exceeds the upper limit, and the address rewriting means further increases the transfer upper limit number of times every time the first e-mail address or the first substitute e-mail address is rewritten. It is also preferable to subtract. When the upper limit number of transfers is subtracted and becomes less than the predetermined number, the address rewriting means does not rewrite the destination of the e-mail. For example, a large amount of unnecessary mail is sent from the second information communication terminal to the first substitute mail address. Even so, the risk of being transmitted as it is to the first information communication terminal is reduced.
[0009]

Subsequently, each component will be described.
[0012]
The address issuance receiving unit 101 is a part that receives an issuance request for a temporary address (first substitute mail address) transmitted from the mobile phone 30 and outputs the issuance request to the address issuance unit 102. This issuance request includes the mail address (first mail address) of the mobile phone 30 and the desired upper limit number of incoming calls.
[0013]
The address issuing unit 102 is a part that issues a temporary address based on the issue request received by the address issue receiving unit 101. The address issuing unit 102 stores the issued temporary address and the mail address of the mobile phone 30 in the address information storage unit 210 together with the upper limit number of incoming calls.
[0014]
An example of information stored in the address information storage unit 210 is shown in FIG. According to the example shown in FIG. 2, “user address”, “temporary address”, “upper limit number of incoming calls”, “number of incoming calls”, “message ID”, and “information distributor address” are associated with the address information storage unit 210. Stored. “User address” is the user's mail address. “Temporary address” is an e-mail address issued by the address issuing unit. The “upper limit number of incoming calls” is the number of times desired by the user, and is the upper limit number of times for performing predetermined processing (details will be described later) on the e-mail. The “number of incoming calls” is the number of times of performing a predetermined process (details will be described later) on the e-mail. The “message ID” is information for distinguishing each of a plurality of “temporary addresses” with respect to one “user address”, for example. The “information distributor address” is the mail address of the information distributor.
[0015]
Accordingly, when the address issuing unit 102 pays out a temporary address for the first time, predetermined information is stored in the “user address”, “temporary address”, “upper limit number of incoming calls”, and “message ID”. The address issuing unit 102 outputs the paid out temporary address together with the corresponding mail address to the address transmitting unit 103.
[0016]
The address transmitting unit 103 is a part that transmits the temporary address issued by the address issuing unit 102 to the corresponding mail address. For example, when there is a temporary address issue request from the mobile phone 30, the temporary address is transmitted to the mobile phone 30. The user using the mobile phone 30 notifies the information distributor of the received temporary address by some means, and the information distributor transmits information using the temporary address (details will be described later).
[0017]
The mail receiving unit 104 is a part that receives an electronic mail transmitted from the information distributor terminal 35 to a temporary address. The mail receiving unit 104 outputs the received electronic mail to the address rewriting unit 105. The mail receiving unit 104 also receives a reply e-mail returned in response to the e-mail transmitted from the mail transmitting unit 106 to the mobile phone 30. The mail receiving unit 104 outputs the received reply e-mail to the address rewriting unit 105.
[0018]
The address rewriting unit 105 rewrites the destination of the e-mail transmitted from the information distributor terminal 35 and received by the mail receiving unit 104 from the temporary address to the corresponding mail address, and distributes the transmission source of the received e-mail to the information distribution This is a part to rewrite from the mail address (second mail address) of the information distributor corresponding to the trader terminal 35 to the reply mail address (second substitute mail address) corresponding to this mail address. More specifically, referring to FIG. 2, if the temporary address is “tmp1@tmp.com” and the mail address of the information distributor is “omise@omise.com”, the destination is Rewrite to “iduki@docomo.ne.jp” and rewrite the transmission source to “tmserver@tmp.com”. The address “iduki@docomo.ne.jp” is the e-mail address of the mobile phone 30, and the sender “tmserver@tmp.com” receives a reply e-mail to the mail transfer system 10 when it is replied. It is an address set to. The address rewriting unit 105 outputs the rewritten e-mail to the mail transmitting unit 106.
[0019]
The address rewriting unit 105 also rewrites the destination of the reply e-mail returned from the mobile phone 30 from the reply e-mail address to the e-mail address corresponding to the information distributor terminal 35, and sets the sender of the return e-mail as the mobile phone 30. Rewrite from the email address to the corresponding temporary address. That is, the address rewriting unit 105 performs rewriting reverse to the above. If the example of FIG. 2 described above is used, the address rewriting unit 105 rewrites the destination of the reply e-mail from “tmpserver@tmp.com” to “omize@omise.com”, and the transmission source is “iduki@docomo.com”. ne. jp "to" tmp1@tmp.com ". The address rewriting unit 105 outputs the rewritten e-mail to the mail transmitting unit 106.
[0020]
The address rewriting unit 105 refers to the “upper limit number of incoming calls” and the “number of incoming calls” stored in the address information storage unit 210 before performing the rewriting described above, ”Is determined. The address rewriting unit 105 performs the above-described rewriting when the “number of incoming calls” does not exceed the “upper limit number of incoming calls”, and does not perform rewriting when the number exceeds.
[0021]
The mail transmission unit 106 is a part that transmits the e-mail or reply e-mail output from the address rewriting unit 105 to the mobile phone 30 or the information distributor terminal 35 according to the rewritten destination.
[0022]
Subsequently, the operation of the mail transfer system 10 of this embodiment will be described with reference to FIG. FIG. 3 is a sequence diagram for explaining the operation of the mail transfer system 10. An issuance request is transmitted as a temporary address payout request from the cellular phone 30 to the mail transfer system 10 (step S01). This issue request is received by the address issue acceptance unit 101 of the mail transfer system 10 and the issue request is output to the address issue unit 102. This issuance request includes the mail address of the mobile phone 30 and the desired upper limit number of incoming calls.

The address rewriting unit 105 determines whether or not this e-mail can be transferred based on the “number of incoming calls upper limit” and “number of incoming calls” stored in the address information storage unit 210 (step S06). The address rewriting unit 105 determines a transfer destination based on the temporary address of the electronic mail, and rewrites the mail address of the destination and the transmission source (step S07). The address rewriting unit 105 outputs an e-mail in which the destination and the transmission source are rewritten to the mail transmission unit 106. Further, the address rewriting unit 105 counts up the “number of incoming calls” of the corresponding part of the information stored in the address information storage unit 210 (step S08).
[0026]
The mail transmission unit 106 transfers the electronic mail whose destination and transmission source are rewritten to the mobile phone 30 (step S09). After confirming the information described in the e-mail with the mobile phone 30, the user transmits a reply to the e-mail as a reply e-mail (step S10). This reply e-mail is transmitted to the mail transfer system 10 and received by the mail receiving unit 104. The mail receiving unit 104 outputs the received reply e-mail to the address rewriting unit 105.
[0027]
The address rewriting unit 105 determines whether or not this reply e-mail can be transferred based on the “number of incoming calls upper limit” and “number of incoming calls” stored in the address information storage unit 210 (step S11). The address rewriting unit 105 determines the information distributor terminal 35 as a transfer destination based on the mail address of the sender (mobile phone 30) of the reply e-mail, and uses the sender mail address as a temporary address and the destination mail. The address is rewritten to the mail address corresponding to the information distributor terminal 35 (step S12). The address rewriting unit 105 outputs an e-mail in which the destination and the transmission source are rewritten to the mail transmission unit 106. Further, the address rewriting unit 105 counts up the number of incoming calls of the corresponding part of the information stored in the address information storage unit 210 (step S13).
[0028]
The mail transmitting unit 106 transfers the reply electronic mail whose address and transmission source are rewritten to the information distributor terminal 35 (step S14).
[0029]
【The invention's effect】
According to the present invention, the e-mail address transmitted from the second information communication terminal to the first substitute e-mail address is rewritten to the first e-mail address corresponding to the first substitute e-mail address. Since the information is transmitted to the information communication terminal, for example, the user using the first information communication terminal can receive the information without disclosing the first mail address to the information provider using the second information communication terminal. . In addition, since the source of the forwarded e-mail is rewritten to the second substitute e-mail address corresponding to the second e-mail address corresponding to the second information communication terminal, the first information for receiving the e-mail Even if the user of the communication terminal performs a normal reply operation, the reply e-mail is not directly sent to the second information communication terminal, and the first e-mail address may be inadvertently sent. Is reduced. Further, the reply email address is rewritten from the second substitute email address to the second email address, the reply email sender is rewritten from the first email address to the first substitute email address, and the reply email is sent. Since the data is transmitted to the second information communication terminal, bidirectional information communication using the first substitute mail address is possible. Therefore, it was possible to provide a mail transfer system that can send and receive electronic mail without knowing a mail address, which is an object of the present invention.
