METHOD FOR MANAGING MAIL USING MESSAGE [0002]

The present invention relates to a mail management method using messaging executed by a server that is capable of accessing mail, wherein the server includes a mailing address of a mail stored in a user's mail inbox, header information of the mail, and body content of the mail. Reads at least one of the included keyword, the attached file attached to the mail to automatically select the mail to be shared and delivered to the program provided in the user's wireless terminal of the mail stored in the user's mail inbox, and the server A third step of assigning a unique identification code to at least one of a header, a body, and an attached file of the mail, wherein the server processes a message for transmitting the mail to which the identification code is assigned to the program of the wireless terminal; The server assigns the identification code to a program of a wireless terminal receiving the message. It relates to a mail management method using the messaging sending data corresponding to one.

A mail (= e-mail) is a message transmitted through a computer communication network, or a message transmitted, which is created by a predetermined mail user agent (MUA) provided in a mail sending client terminal and at least one or more through a communication network. Received through an MTA and / or MDA to a mail server used by a mail receiving client and stored in an electronically implemented mailbox for the mail receiving client on the mail server, and through a predetermined MUA provided in the mail receiving client terminal. The mail is to be accessed at any time. Such a 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 diagram briefly showing the functional configuration of a conventional mail system using a single mail server.

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

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

The MTA provided in the mail server receives a predetermined mail from at least one or more other MTAs and / or MUAs through the Simple Mail Transfer Protocol (SMTP) communication protocol, and sends the received mail to another MTA by calling an MDA, or It is a program to deliver the mail to the mailbox of the receiving client.

When a predetermined mail is received, the MTA sends a local call to a local MDA through a system call if the mail receiving client address included in the header of the received mail is a mail receiving client in charge of the mail. Instructing the received mail to be stored in the mailbox of the mail receiving client, and conversely, if the mail receiving client address included in the header of the received mail is not the mail receiving client in charge of the mail, the mail is forwarded to another MTA. )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 a case of delivering the received mail to the outside and a 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.

Local MDA generally stores the incoming mail in the mailbox of a mail-receiving client on the local file system, optionally using a mail filter (e.g., a program that filters spam) that processes the mail. .

A mailbox is a storage medium that contains a predetermined format for storing mail. Since there is no unified standard format, you can define and use your own format. The method and the method of storing each mail in each directory as a separate file are used, and in most cases, a method of continuously appending to a single file is often used.

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

The MRA is a program for the mail receiving client to remotely access the mailbox through a remote MUA. When a remote MUA provided in a mail receiving client terminal requests an incoming mail to the MRA, the MRA is provided in the mail server. Read / write access of the local file system accesses the mailbox, determines whether there is a mail to be delivered from the mailbox to the remote MUA, and extracts at least one mail from the mailbox if there is a mail to be delivered to the remote MUA. To transmit to the remote MUA. The latest 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 mail system is divided into several small mutually independent components as described above, because various kinds of systems can be obtained through various combinations of various components. Recently commercialized mail servers include a Dispatcher System, a Delivery Interface, a Retrieval Interface, an Authentication System, or a Mailbox Location Search component. A cluster-based mail system, which is further extended to the system, is used, and typical cluster-based mail systems include Duke University's shipping system, EtherLink Network's EtherLink system, Washington's Percupine system or UC Berkeley's NinjaMail system.

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.

As described above, in a conventional mail server and / or a mail system, at least one or more second clients strictly restricts access to mail received by the MTA and / or mail stored in a mailbox through a local MDA. It is intended to protect the privacy of the client that owns the mail, and at least one second client's access to the mail is essentially blocked.

In addition, in the case where the shared mail is shared by at least one or more second clients in the client, various other methods (for example, a shared mail method, It is obvious that a method of obtaining a client's real-time approval in the process of providing a share, or an implementation method of obtaining approval using an OTP in the process of sharing a shared mail) can be provided. As a result, the method of FIG. 12 is only one representative method for efficiently explaining among various methods included in the technical idea of the present invention, and the technical idea of the present invention is not limited to the case of FIG. 12 It will be obvious.

Referring to FIG. 12, a client accesses (1200) a mail server 200 through a web browser 280 (or MUA) provided in a client terminal 270 and stores the shared mail stored in the storage medium 1 (In the case of FIG. 12, since the access right is added to the mail share information, the access approval process is omitted in the process of sharing the shared mail) At least one second client grants a predetermined access right to access the shared mail 1205 and sets a shared mail providing path for sharing the shared mail with the at least one second client 1210 ).

According to an embodiment of the present invention, a shared mail providing path for sharing and sharing the shared mail with at least one second client includes a path using the web browser 280 of at least one second client, a path using the MUA, There may be a route using the messenger 285 and / or a route using the predetermined communication program 290, and in this drawing 12, a shared mail providing route using the instant messenger 285 is used. Of course, when the shared mail providing path is fixed to a specific path, the process of setting the shared mail providing path as described above may be omitted.

If the shared mail providing path is not the instant messenger 285 (1215), the mail server 200 provides the shared mail to the at least one second client through the shared mail providing path set by the client (1220).

If the shared mail delivery path is an instant messenger 285 of at least one second client 1225, the mail server 200 may send an instant messaging function (e.g., instant messenger 285 of at least one or more second clients) (1230) a function of transmitting an attached file of the main content through a communication port and a communication protocol to be used), and, through the instant messaging function, whether the at least one second client is currently using the corresponding instant messenger (285) (1235).

If the at least one second client is not currently using the instant messenger 285, the mail server 200 determines whether the at least one second client uses the instant messenger 285 , When the at least one second client logs in to the instant messaging network by executing the instant messenger 285 at the client terminal 270).

On the other hand, if the at least one second client is currently using the instant messenger 285 (1250), the mail server 200 extracts the attachment file from the shared mail to be shared with the at least one second client (Step 1255), and transmits the attachment file of the extracted shared mail to the instant messenger 285 of the at least one second client through the activated instant messaging function (step 1260).

According to a preferred embodiment of the present invention, the method of transmitting the attachment of the shared mail to the instant messenger 285 may be based on a data transmission method based on a communication protocol provided in the instant messenger 285.
