Abstract

PURPOSE:To deliver an electronic mail to a desired destination at all times by providing newest information relating to a destination to each computer. CONSTITUTION:When information relating to destination 15 registered, deleted or revised in a computer 2a, a user management function 5 extracts an address of other computer connecting to a network 1 from a network management area 3 to generate an electronic mail for destination management. The electronic mail for destination management includes at least an address of other computer, an address of its own computer and information relating to registered, deleted or revised destination. Thus, the electronic mail for the said destination management is delivered in terms of a multiple address mail to other computers by a mail transfer function 6. Then the content of a destination management area 4 of its own computer is edited by the user management function 5 based on the registered, deleted or revised destination.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an e-mail system that performs e-mail communication between computers via a network.

(Prior Art) With the recent progress in networking between computers, e-mail systems that deliver e-mails between computers have become widely used.

With this e-mail system, a message (e-mail) is first input from a computer into a mailbox installed on a magnetic disk, etc., and when the recipient receives a call in his or her mailbox, the contents are displayed on the screen or printed out. It is something that does.

By the way, as mentioned above, when inputting an e-mail into a mailbox, it is necessary to specify the mailbox, that is, the destination, and the destination generally includes the node name (the other party's computer) and the login name (the other party's computer). personal name).

However, these destinations such as node names and login names traditionally depended on the user's memories and records;
There is a problem in that the e-mail cannot be delivered to the desired destination if the user forgets or does not know the destination, or if the destination is changed.

(Problems to be Solved by the Invention) As described above, in the conventional e-mail system, e-mail is delivered to the desired address when the user forgets or does not know the address, or when the address is changed. The problem was that I couldn't do it.

The present invention was made based on such circumstances, and always includes:
The purpose of this invention is to provide an e-mail system that can deliver e-mail to a desired destination.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned problems, the present invention provides an e-mail system in which a plurality of computers are connected via a network and e-mail communication is performed between the computers. , each computer has a storage means for storing information regarding e-mail destinations for other computers, and a storage means for storing information regarding e-mail destinations for other computers, and a means for transmitting the contents to all other computers by e-mail when information regarding the destinations of its own computer is registered, deleted, or changed. a broadcast notification means for sending a notification;
a determining means for analyzing the content of the e-mail sent from the network and determining whether the content is related to registration, deletion, or modification of the destination; and content of the e-mail related to registration, deletion, or modification of the destination; and editing means for editing the information stored in the storage means based on this content.

(Function) In the present invention, each computer has information regarding the destinations of other computers, and if any computer registers, deletes, or changes that information, the information regarding the destinations is edited in all computers. It will be the latest one. Therefore, the user can always deliver e-mail to the desired destination based on the information regarding the destination.

(Example) Hereinafter, details of embodiments of the present invention will be explained based on the drawings.

FIG. 1 is a diagram showing the configuration of a computer system to which the e-mail system of the present invention is applied.

In the figure, 1 indicates a network, to which a plurality of computers 2a, 2b, . . . are connected.
Communication such as e-mail is carried out via the .

FIG. 2 is a diagram showing a partial configuration of each computer 2 a s 2 b .

In the figure, 3 is a network management area that holds the addresses of other computers connected to network 1;
5 is a destination management area that stores information about the destinations of the own computer and other computers, and 5 is information about the destinations in the destination management area 4 of the own computer based on the contents when the information about the destinations in the own computer is registered, deleted, or changed. This is a user management function that allows you to edit the content and create e-mails to send the contents to other computers.

Further, 6 is a mail forwarding function that delivers the e-mail to network 1 and also distributes the e-mail from network 1 and determines its content, and 7 is the content of the delivered e-mail to register, delete, or change the destination. This is a mail editing function that edits the information regarding the destination stored in the destination management area 4 based on the contents of the message.

Note that 8 indicates an e-mail, and there are two types of e-mail 8 in this embodiment: an e-mail for destination management and a normal e-mail.

FIG. 3 is a diagram showing the contents of the destination management area 4, in which the node name and login name of each computer are stored in a table format.

Next, the operation related to destination management in the e-mail system configured as described above will be explained based on the flowchart shown in FIG.

For example, in the computer 2a, when information regarding a destination in the own computer is registered, deleted, or changed (Sll), the user management function 5 first retrieves the address of another computer connected to the network 1 from the network management area 3 (512). ), create an email for destination management (
S13). This e-mail for destination management includes at least information regarding addresses of other computers, addresses of the zero computer, and registered, deleted, or changed destinations.

The above e-mail for destination management is then delivered to other computers as a broadcast e-mail by the e-mail forwarding function 6 (
S14). At the same time, the contents of the destination management area 4 of the 0 computer are edited based on the destinations registered, deleted, or changed by the user management function 5 (S15).

On the other hand, the other computer that has received the e-mail for destination management (S21) first analyzes the e-mail using the mail forwarding function 6. (
S23).

In this case, since the e-mail is for destination management, the mail editing function 7 edits and stores the information regarding the destination stored in the destination management area 4 based on the contents of the e-mail (S24.525). ).

Note that when the received e-mail is a normal e-mail, it is delivered to the corresponding user (826).

In this way, in the e-mail system of this embodiment,
Each computer stores information regarding the destinations of other computers in the destination management area 4, and when that information is registered, deleted, or changed on any computer, the contents stored in the destination management area 4 on all computers will be changed. The content will be edited, so
The information in the destination management area 4 is always the latest. Therefore, the user can always deliver e-mail to a desired destination based on the information in the destination management area 4.

In the above-described embodiments, the computers are connected to the network in the form of a bus, but other forms such as a star shape or a ring shape may also be used.

Further, the present invention can be implemented regardless of whether the network is a private network or a public network.

[Effects of the Invention] As explained above, according to the present invention, since each computer has the latest information regarding the destination, e-mail can always be delivered to the desired destination.
