A mail (= e-mail) is a message transmitted or transmitted through a computer communication network. The message is created by a predetermined MUA (Mail User Agent) provided in the mail sending client terminal, Mail server via the MTA and / or the MDA, and stores the received mail in the mailbox that is electronically implemented for the mail receiving client on the mail server, and transmits the mail via the predetermined MUA provided in the mail receiving client terminal So that the user can access the mail from time to time. The above-described mail system is defined in a Message Handling System (MHS) of the International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) Recommendation 400 series.

1 is a view schematically showing a functional configuration of a conventional mail system using a single mail server.

In particular, FIG. 1 illustrates a mail server and a mail system that receive a predetermined mail through a single mail server according to the standard message communication processing system (MHS) of the ITU-T recommendation 400 series.

Referring to FIG. 1, a process of receiving a predetermined mail and confirming the received mail is described below.

An MTA provided in a mail server receives a predetermined mail from at least one other MTA and / or MUA through a Simple Mail Transfer Protocol (SMTP) communication protocol, calls the received mail to another MTA, It is a program to be delivered to the mail receiving client's mailbox.

If the mail receiving client address included in the header of the received mail is a mail receiving client in charge of itself, the MTA sends a local MDA (Local MDA) through a system call If the mail receiving client address included in the header of the received mail is not the mail receiving client in charge of the receiving mail, the control unit instructs another MTA to forward the mail )do.

The MDA provided in the mail server is a program used by the MTA for delivering the received mail to the mail receiving client, and is divided into the case of delivering the received mail to the outside and the case of delivering the received mail to the inside.

When the MDA delivers the received mail to the outside, each MDA exists according to a channel (for example, TCP, UUCP, or the like), and is driven by "/ bin / sh" in case of the UNIX series. When delivering the received mail to the inside, the MDA for storing the received mail in the mailbox of the mail receiving client is called a local MDA. For example, programs such as " procmail "," / bin / mail " have.

The local MDA typically stores the received mail in a mailbox of a mail receiving client in a local file system, and may use a mail filter (e.g., a program that filters spam) filtering the mail in some cases .

A mailbox is a storage medium including a predetermined format for storing mail. Since there is no standardized format that is currently unified, it is possible to define and use a self-format, but in general, And a method of storing each mail in each file in a single directory. In many cases, a method of adding a continuous file to one file is used in many cases.

When a predetermined mail is received in the mailbox as described above, the mail receiving client corresponding to the recipient of the received mail must remotely access the mailbox through the remote MUA provided in the corresponding mail receiving client terminal. To this end, The mail server is provided with at least one Mail Retrieval Agent (MRA) including a POP (Post Office Protocol) daemon and / or an IMAP (Interactive Mail Access Protocol) daemon.

The MRA is a program for remotely accessing the mailbox by the mail receiving client through the remote MUA. When a remote MUA included in the mail receiving client terminal requests a received mail by the MRA, Accessing the mailbox through the read / write rights of the local file system, determining whether there is a mail to be delivered to the remote MUA from the mailbox, extracting at least one mail from the mailbox if there is a mail to be delivered to the remote MUA To the remote MUA. The current version of the POP daemon is POP3, and the latest version of IMAP is IMAP4.

The remote MUA is a mail client program provided in a mail receiving client terminal. Examples of the mail client program include a mail service such as Outlook Express from Microsoft, Netscape Mail from Netscape, usr / ucb / mail ". In recent years, there has been a case of using a web browser including Microsoft Internet Explorer as a remote MUA (for example, Web-based Mail).

The reason why the mail system is divided into several small mutually independent components as described above is that various types of systems can be obtained through various combinations of various components. Recently, the mail server that is being commercialized is provided with the components of a single mail server as a Dispatcher System, a Delivery Interface, a Retrieval Interface, an Authentication System, or a Mailbox Location (Cluster Base Mail System), which is an extended version of the cluster-based mail system, has been used. In addition, a representative cluster-based mail system includes a Duke University dispatch system, an Enderlink system of EarthLink Network, The Porcupine system at the University of Washington, or the NinjaMail system at UC Berkeley.

However, conventional mail servers and / or mail systems may be in the form of a single mail server or a cluster-based form, or may be a mail received from another MTA or a given MUA to an MTA (e.g., ) And / or access rights to the mail stored in the mailbox via the local MDA are allowed only to the mail receiving client and / or the mail sending client (for example, the mail stored in the sending mail box), and the other at least one second client Access to mail is strictly restricted, and if at least one second client accesses the mail received at the MTA and / or the mail stored in the mailbox via the local MDA, it may be illegal to access the unauthorized information system Or hacking to gain unauthorized rights illegally.
