Abstract

PURPOSE: Two bytes characters stream recipient ID E-mail mailing service system of a computer communication or an internet E-mail is provided to process two bytes character stream without an encoding or a decoding process. CONSTITUTION: Two bytes characters stream recipient ID E-mail mailing service system of a computer communication or an internet E-mail forms a mail address ID database formed with two bytes character stream independently of a mail server for managing a mail reception routing path. The mail address ID database processes a mail received to a host with a mail server. A transmitted mail is stored to a mail reception box if a character stream corresponding to a recipient ID of the transmitted mail exits on the mail address ID database. The transmitted mail is intercepted if not.

Description

2-byte string of computer communication or Internet e-mail Recipient ID E-mail mailing service system {2 BYTE LETTER ADDRESS E-MAIL MAILING SERVICE SYSTEM}

The present invention relates to a mailing service of e-mail using a PC communication or the Internet, and more particularly, to non-English characters such as Korean, Chinese, and Japanese, including English-speaking characters consisting of ASCII code. The present invention relates to a 2 BYTE string recipient ID email mailing service system that enables an email service even for a 2 BYTE string recipient identification.

In general, in the mailing service of e-mail using PC communication or the Internet, the recipient ID of the e-mail is a 7-bit string of ASCII code in the early English, so SMTP (Simple Mail Transport Protocol) Protocol) is configured to allow only 7 bit strings to pass through.

As the use of personal computers and the Internet has increased, the need for compatibility with documents created with general programs, word processors, spreadsheets, and other applications has emerged. file) is 8 (Most Significant Bit) value of 1 unlike MSB (Most Significant Bit) value, which is the first bit of each string, is 0 (zero) and 7 bit length. It is now a binary format represented by a sequence of bits. On the other hand, since non-English characters are represented by 2 BYTE 16 bit, the mailing service of SMTP e-mail using 7 bit string is the most basic system function of the kernel of the server. The recipient ID of the e-mail using non-English characters is treated as an error that is incorrectly input in the existing e-mail mailing service.

However, due to the internationalization of the Internet, the necessity of transmitting an e-mail address of a string consisting of 2 BYTE 16-bit non-English characters other than the ASCII code of English is required. Encoding represented in ASCII code and decoding method of converting it into 8 bits are devised and utilized.

On the other hand, the use of non-English characters e-mail address through encoding and decoding enabled e-mail mailing service using non-English characters, but it did not recognize non-English characters as their own characters and simply means the mechanical correspondence to the keyboard. It is a temporary and incomplete e-mail mailing service in that it is recognized and processed as a set of English alphabets (alphabet). In addition, when a native language domain is realized in a non-English speaking country, a method of using a non-English character e-mail address through encoding and decoding cannot be used.

The present invention is to solve the problem of the non-English character e-mail address by the above encoding and decoding, the object of the present invention is to establish a mail server system that does not use a system account e-mail mailing does not depend on the system user We want to implement a service system.

Another object of the present invention is to complete a complete e-mail address (for example, administrator@cheongwadae.government.korea) together with the native language domain when the native language domain is realized in a non-English speaking country.

In order to achieve the object as described above, the 2 BYTE string recipient ID mailing service system of PC communication or Internet e-mail according to the present invention is independent from a mail server managing a mail receiving routing path, 2 Construct a mail address ID database consisting of BYTE strings, and correspond to the recipient IDs that have been processed and transmitted from the mail address ID database independently by interfacing with the mail server. If the character string exists in the mail address ID database, the mail is stored in the designated mail inbox by the MDP (Mail Delivery Program) that delivers the mail, and the mail received in the host is independently linked with the mail server. The string corresponding to the receiver ID processed and sent from the database does not exist in the mail address ID database. If it has features that you refuse to receive mail.

Next, a 2 BYTE string recipient ID e-mail mailing service system of PC communication or Internet e-mail according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual diagram of an e-mail mailing system of the present invention. When e-mail has been sent to the MTP (1) of the server by the MTP (Mail Transfer Program) of another server, the MTP of the server receives a mail transfer request (1.1), A mail account registered in the user database (3) to check (1.2) the mail account user (or mail recipient ID) of the server without passing through the kernel of the server operating system to the mail sent. The user 3.1 is searched to confirm the presence or absence of the recipient ID of the transmitted mail, and to determine whether to receive the mail (1.3). At this time, when the recipient ID is confirmed and mail is received, the mail account user ID and user mailbox directory, etc. are stored through the MDP (Mail Delivery Program) to store the mail in the user environment (1.4). The user's environment is searched (2.1), and the mail is stored in the designated user's mailbox (2.2).

FIG. 2 is an overall flowchart illustrating the process of FIG. 1. Viewing mail sent from another server's MTP The server's MTP receives a request to send a mail, and analyzes the host of the mail address (host: e-mail @ back address ID, e.g. @ yahoo.com). Make sure the server is a host. If the server is not a host, the mail is returned if the mail is sent incorrectly. If the server is a host, the recipient ID of the received mail (user ID in front of the e-mail) is a non-English string of 2 BYTE. If it is a Korean character string, search the registered information of the Korean mail account user registered in the database. If the address of the received mail is an English character string, search the registered information of the English mail account user registered in the database. It checks whether the user exists and receives the mail if the user exists, and rejects and returns the mail if the user does not exist.

Received mail is searched for the mail account user environment by MDP and stored in the user's mailbox, and the user later receives and reads the mail stored in the server through MUP (Mail User Program). It becomes possible.

3 is a flow chart illustrating the server MTP portion of FIG. 2 in more detail. When receiving a mail transmission request from another server through MTP, it first checks the address ID of the mail and checks whether the server is a host. Since e-mail creates a user around the host, Mail entering a relay must be rejected at the receiving stage of the mail transmission request for the stability of the system.

When it is confirmed that the server is a host, the next step is to check whether the recipient ID of the received e-mail is a non-English string of 2 BYTE, that is, Korean or English. The present invention provides an e-mail of Korean ID and English ID. Since it is considered to use both, user information separated into Korean and English is inputted into the database. Accordingly, the user information is searched separately into Korean and English.

If the recipient ID of the mail requested through mail account user information search exists, the received mail is stored in the user's mailbox according to the user mailbox directory information. If the recipient ID does not exist, the mail is rejected and returned. .

Up to now, the method of receiving a mail transmission request of an e-mail in a 2 BYTE non-English string has been described. On the other hand, when sending an email with a recipient ID of a 2 BYTE non-English string, if the user's MUP (Mail User Program) does not recognize it as an e-mail address, the MUP does not recognize it for processing. You need to patch the part (a temporary replacement for a failed part of the data) to skip that logic.

4 is a flowchart illustrating a process of patching an e-mail recipient ID not recognized by the MUP of the present invention. The user executes MUP to compose and send the mail. The MUP checks the recipient ID of the mail sent and if it is confirmed by the e-mail address, that is, if it is confirmed by the English e-mail recipient ID, it is sent. Patch the recipient ID of the e-mail address, i.e. the recipient ID of the 2 BYTE non-English string, and force it to be sent. Therefore, when sending an e-mail, an e-mail is sent regardless of the 2 BYTE non-English string recipient ID.

As described above, the present invention relates to a 2 BYTE string recipient ID composed of non-English-speaking characters such as Korean, Chinese, and Japanese as well as English-speaking characters consisting of ASCII code in e-mail using PC communication or the Internet. If the native language domain is realized by direct processing through the user database without the process of encoding and decoding the postal mailing service and conforming to the standards related to the mail transmission, if the native language domain is realized, complete email with the native language domain This has the effect of completing the address.
