Abstract

PURPOSE:To select automatically an 0/R name in kanji or in alphanumerics by retrieving a user definition file whose 0/R name is registered by plural forms and selecting the same form as the 0/R name of an identified recipient. CONSTITUTION:The 0/R name of each user is registered in a user definition file 2 in plural forms in kanji and in alphanumerics. When a sender being a user sends an electronic mail, the transmission mail is generated by using a mail command 5 of a computer 1 and the mail is given to a mail transfer program 6. The program 6 identifies the form of the 0/R name of the recipient designated by the user and selects the 0/R name of the same form by retrieving the file 2 and a network information file 4 decides the computer 1 being a mail distribution destination. Thus, the user sends a domestic or an international mail without notifying the form of its own 0/R name thereby improving the operability of the user.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic mail system.

[0002]

2. Description of the Related Art M is an international standard for electronic mail systems.
The HS (Message Handlig System) manages mails using addresses called O / R names to identify senders and recipients. By the way, since the senders and receivers of e-mails are not necessarily humans, there are various types of O / R names. For humans, the names of countries / administrative agencies (ADMD), private areas (PRDM) name, organization name
It is common to use a combination of department name and individual name.

However, regarding the organization name, department name, and personal name among the elements constituting the O / R name, alphanumeric characters are to be used in the MHS international standard, and Kanji is used for the mail address. In Japan, there is something strange.

Therefore, OSI (Open Systems Interconne
INTA, which is developing implementation rules in Japan
In P, these elements have been expanded so that Kanji can also be used. As a result, in Japan, a mixture of e-mail systems that can use alphanumeric characters and Kanji as O / R names and systems that can only use alphanumeric characters. It has become.

[0005]

However, in such a conventional electronic mail system, even if an alphanumeric character and a Chinese character can be used as the O / R name, these are matched with the format of the recipient's O / R name. There is no one that can be automatically selected and used. Therefore, if the system used for exchanging e-mails internationally is used to send to domestic recipients, the recipients are the same. Even Japanese people had to send it in alphanumeric format, which caused a sense of discomfort.

The present invention has been made in view of the above-mentioned conventional problems, and each user has an O / R format in the form of alphanumeric characters.
If both the first name and the K / O name of the Kanji are registered and the user as the sender tries to send to a certain recipient, the O / R name of the other recipient is in the alphanumeric format or the Kanji character. It is possible to automatically identify whether the format is the same, to send the sender's O / R name in the same format as the identified format, and to be able to freely send and receive e-mail both in Japan and overseas with one e-mail system. The purpose is to provide an e-mail system that

[0007]

According to the electronic mail system of the present invention, a user definition file for registering each user's O / R name in plural formats of alphanumeric characters and Chinese characters, and a user who is a sender specify. The O / R name format of the recipient is identified, and the O / R name format of the sender is used as the O / R name format of the sender.
O / R name format automatic selection means for selecting the same format as the R name format from the user-defined file, and network information for determining the computer to which the mail is delivered for each O / R name format of the recipient And files.

In the electronic mail system of the present invention, the O / R name format automatic selection means identifies the dominant format as the O / R name format of a plurality of recipients during the broadcast transmission.
It may have a function of selecting the same format as the identified format from the formats of the O / R names registered in the user definition file.

[0009]

In the electronic mail system of the present invention, the O / R name of each user is registered in the user definition file in a plurality of formats of alphanumeric characters and Chinese characters, and when the sender who is the user sends an electronic mail. The O / R name automatic selection means identifies the format of the O / R name of the recipient, and the format of the O / R name of the sender is the same as the format of the O / R name of the identified recipient. In this case, the computer of the mail delivery destination is determined for each O / R name format of the recipient by the network information file.

In the electronic mail system of the present invention,
At the time of the broadcast transmission, the O / R name format automatic selection means identifies the dominant format as the O / R name format of a plurality of recipients, and the O / R name registered in the user definition file. The same format as the identified format can be selected from the formats.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 shows the system configuration of an embodiment of the present invention. The computer 1 is provided with a user definition file 2, a mailbox 3 for each user, and a network information file 4, and the computer 1 A mail command 5 and a mail transfer program are registered in the memory. 7 is a data link.

In the user definition file 2, a directory name to be a mailbox and various O / R names are defined and registered for each user. FIG. 2 shows the data structure of the user definition file 2, and one record 21 is assigned to each user. This user record 21 records information about each user, and as shown in the enlarged view, regarding the user “Ichiro Yamada”,
The mailbox is "/ usr / mail / yamada", and the O / R name in Kanji format is "/ (ADMD name, PRMD name omitted) / Tozai Denki / Tokyo Factory / Yamada-Ichiro" and alphanumeric format O. "/ (ADMD name, PRMD name omitted) / EWEC / tokyoworks / yamada-ichiro" is registered as the R name, and "DDA: FAX / 8024567" is registered as the FAX format of the area definition attribute list.

The mailbox 3 is provided for each user. In reality, one directory on the magnetic storage disk corresponds, and each received mail is stored as a file below it. .

The network information file 4 stores information for determining the destination computer from the O / R name of electronic mail.

The mail command 5 registered in the computer 1 is used for the user to create and send a mail and to read the received mail in the mail box 3. The transfer program 6 is used to create and send a mail by the mail command 5 or to receive a mail from the partner computer.

The data link 7 is a virtual view of a communication path for exchanging information with a partner computer, and is actually composed of various networks such as a communication line, a packet network, and a LAN.

Next, the operation of the electronic mail system having the above configuration will be described.

As shown in FIG. 3, when a user tries to send an e-mail to a recipient who is a specific user, the user as the sender creates the outgoing mail 8 by the mail command 5 shown in FIG. Then, it is passed to the mail transfer program 6. This outgoing mail 8 also contains the O / R name of the recipient.

The mail transfer program 6 sends the sent mail 8
The destination computer and the destination computer to which the mail is to be sent are determined from the network information file 4, and the mail transfer is executed.

As shown in the enlarged view, the network information file 4 has a set of a part of the O / R name and the computer name of the transmission partner corresponding thereto as one record, and the alphanumeric O / R name "/ (ADMD name and PRMD name omitted) / EWE
C / HQ / sales = HostA ”and K / O name“ / (ADM
D name and PRMD name are omitted) / Tozai Electric / Headquarters / Sales Department /
= HostA "as one record, and also" / (ADMD name,
PRMD name omitted) / EWEC / HQ = HostB ”and“ / (ADMD
Name and PRMD name are omitted) / Tozai Electric / Headquarters / = HostB ”as another record.

Therefore, the address is in Kanji format, "Tozai Denki Headquarters / Sales Department Mr. Sato" or in alphanumeric format, "EWEC H
If it is Mr. Sato of Q sales, it will be transferred to the computer of host A and the destination will be in Kanji format "Mr. Tanaka of Tozai Electric Headquarters / Engineering Department" or in the alphanumeric format "EWEC HQ Engineer
If it is "Mr. Tanaka", it is transferred to the computer of host B.

At the time of this transfer, the mail transfer program 6 executes the processing as shown in FIG. First, when using an O / R name in Kanji format, the mail transfer program 6 is defined by the user by setting the destination to "/.../Tozai Electric / Tokyo Factory / Yamada-Ichiro" as in the outgoing mail 8a. The corresponding K / K format O / R name is searched from the file 2 and the sender's display is also sent in the Kanji format to the registered mailbox 3 of Mr. Yamada.

Similarly, when the alphanumeric O / R name is used, the destination is "/.../EWEC/to" as in the outgoing mail 8b.
kyoworks / yamada-ichiro ”, the mail transfer program 6 searches the user-defined file 2 for the corresponding alphanumeric O / R name, and sends the same to the registered mailbox 3 of Yamada The display is also sent in alphanumeric format.

Similarly, the area attribute definition list format O / R
When the first name is used, the destination is set to "DDA: FAX / 8024567" as in the outgoing mail 8c, and the same is sent to the mailbox 3 of Mr.

As described above, in the electronic mail system of this embodiment, whether the O / R name is in the alphanumeric format or the Kanji format, the same mailbox is sent to the same destination regardless of the format. It can be sent to and stored there. For this reason, if the user registers various O / R names in the user definition file, all that is required is to manage one mailbox. However, it will be possible to receive in other formats.

The present invention is not limited to the above embodiment. For example, in the case of multi-address transmission, that is, when there are a plurality of destinations and there are various O / R name formats, it may be confused as to which format should be used. In such a case, the O / R name with the highest priority is set as the sender's O / R name. For example, when the MHS alphanumeric and Kanji O / R names are mixed, the alphanumeric O / R names are common to all countries, but Kanji is valid only in Japan. If the priority of the O / R name in the numerical form is set to be high, any recipient can understand the meaning of the mail even if the overseas transmission and the domestic transmission are performed in a broadcast manner.

[0028]

As described above, according to the present invention, O / R
Names are defined and registered in multiple formats, and the O / R name in the same format as the recipient's O / R name is automatically selected as the sender name when sending an e-mail. You can send domestic and international mails without paying attention to the O / R name format, and conversely, even if you receive emails from domestic and overseas with multiple types of O / R name for one user. Since it can be received by one mailbox, the operability for the user is significantly improved.
