Description

The present invention relates to a technique for automatically discriminating and distributing electronic mail (hereinafter referred to as mail), and in particular whether to permit or reject mail distribution based on information such as registration information of the sender of the mail and usage status of transmission. The present invention relates to an e-mail transmission / reception system and method that can automatically discriminate.

Conventionally, in order not to receive unnecessary emails or unwanted emails (hereinafter referred to as spam emails), these email addresses are registered in advance as email addresses to be rejected, and emails at those addresses are excluded. This is generally done. However, this method requires a mail address to be registered each time for a newly generated junk mail or the like, and the work is difficult.

On the contrary, there is a method of registering only e-mail addresses that are permitted to be received in advance, but this makes it impossible to receive e-mails transmitted from unknown destinations.
In particular, when an e-mail address is displayed on a homepage or an advertisement, e-mails are received from a large number of unknown unspecified senders, so this method cannot distinguish between unnecessary e-mails and necessary e-mails.

In addition, there is a method in which a specific word or the like is registered in advance, and it is determined whether or not the word or the like is present in the mail contents. (Refer to Patent Documents 1 to 4) However, there is a risk that this method also eliminates an email to be received.

In addition, it is also considered to embed information such as passwords in the title of the email or in the text (see Patent Documents 5 to 6). Considering use from a mobile phone or the like, models of various ages are used. At present, it is difficult to automate all mobile phones, and manual embedding is troublesome and impractical.

Each mobile phone company or provider has taken measures such as restricting mass delivery of unsolicited e-mails and stopping services to mass senders, but individuals and small groups distributed on the Internet around the world Monitoring and regulation of the mail server's transmission status has not been realized by conventional technology.

In the above-described method, it is not possible to automatically determine whether or not mail can be received from an unspecified number of unknown senders when the mail address is open to the public.

Conventional e-mail addresses cannot be sent without knowing each other's e-mail address at the time of transmission, so even if it is not disclosed on the home page or advertisement, it will be sent unwanted e-mail such as junk e-mail due to malicious diversion or outflow There was a possibility.

The conventional e-mail address can usually be sent from any sender, which causes unnecessary e-mails such as unwanted e-mails due to malicious misuse or outflow.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic determination method for determining whether or not an e-mail can be received and a mail server that can solve the above problems.

The method for determining whether or not an e-mail can be received according to the present invention is disclosed by registering the user in the database of this system, not a direct mail address (e-mail address of a mobile phone or a mail address mainly used by a user on a personal computer). By using a one-way dedicated e-mail address that is a combination of the sender's public address and the recipient's public address, and inquiring and registering information in the database with this combined e-mail address when receiving Whether or not the mail can be received is automatically determined based on the registration information of the sender, the number of transmissions per day or hour of the sender, and other usage conditions.
The sender address field of the received mail received by the receiver deletes the direct mail address of the sender and displays a one-way dedicated address for reply (reverse direction).
When a user publishes an e-mail address on a homepage or advertisement, the issued e-mail address is displayed, and a user who has already been registered in the database of this system and has been issued a public e-mail address When sending to the other party, send both addresses together, and when an unregistered person sends it in the normal way, it will be received as set by the recipient, or the mail will be reserved or discarded and registered in this system Reply to the sender with an email requesting

Since the sender's mail transmission status and other information are sequentially recorded in a database, and mail is automatically identified based on the information, mass senders such as junk mail can be detected and received in real time.

Direct e-mail addresses can be sent and received without being known to each other, and it is impossible to send any dedicated e-mail address from other e-mail addresses, so it is possible to prevent the collection of e-mail addresses and the occurrence of misuse.

Based on the sender's basic information, you can restrict reception by age, gender, occupation, residence area, etc.
In addition, by setting a restriction not to receive information that does not have basic information attached in transmission, the receiver can know the first sender well.

A registered user of a mail distribution system according to the present invention (hereinafter referred to as the present system) registers a public mail address (for example, 1234) corresponding to a direct mail address (for example, foo@docomo.ne.jp) by registration in the system. @ Zid.jp etc.).
[Example 1]

When transmitting from the registered user A (public address 1234@zid.jp) to the registered user B (public address abcd@zid.jp), To (destination address) is set to “abcd1234 by a combination of A and B addresses. @ Zid.jp ”(before @ the recipient's public address + sender's public address).

When transmitting from the registered user B (public address abcd@zid.jp) to the registered user A (public address 1234@zid.jp), To (destination address) is set to “1234abcd” by the combination of the A and B addresses. @ Zid.jp ”(before @ the recipient's public address + sender's public address).

E-mail sent from registered user A (public address 1234@zid.jp) to registered user B (public address abcd@zid.jp) with the dedicated combination address “abcd1234@zid.jp” as the destination Is processed inside this system, From (source address) is rewritten from the direct mail address of registered user A to the reply-only combination address “1234abcd@zid.jp”, and To (destination address) is registered user B Will be rewritten to the direct mail address.

When the registered user B replies, it is only necessary to reply the received mail as it is.
The returned mail is processed inside this system, and From (source address) is rewritten from the direct mail address of registered user B to the return combination address “abcd1234@zid.jp”, and To (destination address) is Rewritten to the registered user A's direct mail address.
Thereafter, transmission and reception can be performed without knowing each other's address.
[Example 2]

When the registered user A (public address 1234@zid.jp) transmits to the unregistered person C (direct address foo@docomo.ne.jp), To (destination address) is set to “foo&docomo.ne.jp1234@zid.jp”. jp "(the recipient's direct address @ replaced with & + the sender's public address).
The sent mail is processed inside the system, and the From (source address) is rewritten from the direct mail address of the registered user A to the public address “1234@zid.jp” of the registered user A, and To ( (Destination address) is rewritten to the direct mail address of the unregistered person C.

When unregistered person C replies to this mail, this system temporarily stores the received mail, 1 for unregistered person C, registered user A uses this system to prevent spam mail That.
2. The fact that unregistered person C needs to register in this system in order to deliver mail to registered user A.
3. Registration method and conditions for this system.
Automatically reply to e-mail notifications.
When the unregistered person C who has read this completes registration in the system, the mail temporarily stored is automatically transmitted to the registered user A.
Thereafter, it can be transmitted and received as a registered user as in the first embodiment.
[Example 3]

When the unregistered person D sends a mail to the public address (1234@zid.jp) of the registered user A, it can be sent by a normal method. The To (destination address) is the public address “1234@zid.jp” of the registered user A, and the From (sender address) is the direct address of the unregistered person D.

This system temporarily stores the received mail, 1 for unregistered user D, and registered user A is using this system to prevent spam mail.
2. The fact that an unregistered person D needs to register in this system in order to deliver mail to registered user A.
3. Registration method and conditions for this system.
Automatically reply to e-mail notifications.
When the unregistered person D who has read this completes registration in the system, the temporarily stored mail is automatically transmitted to the registered user A.
Thereafter, it can be transmitted and received as a registered user as in the first embodiment.

In each of the above implementations, this system records the number of registered users' email transmissions and can regulate transmissions that exceed the prescribed daily transmission number.

In addition, depending on the settings of the management operator or arbitrary settings of registered users,
1. Transmission / reception restrictions for each registered user 2. Transmission / reception restrictions based on information such as the age and gender of the registered user 3. Residential transmission restrictions based on information such as the mail transmission status of the registered user 4. Attaching basic information (age, gender, residential area, occupation, etc.) of the registered user to an email (If not attached, it will not be received)
5. In the above restriction, selection such as rejection, transfer, browsing as Web mail, etc. can be determined.
