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 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.

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

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 mail receiving client terminal.

Accordingly, the search server searches for the mail sharing information as shown in FIG. 5 according to a preferred embodiment of the present invention, (For example, a shared mail set to "X-SearchPermission: ALL") in which the item "X-SearchPermission:" is set to allow the full search is matched with the search word entered by the at least one second client It is desirable to search for mail. According to another embodiment, if the at least one second client has logged in to the search server, the search server may determine that the &quot; X-SearchPermission: &quot; And searches for the set shared mail and the shared mail allowing the at least one or more second clients to search through the inputted search word.

9 (a), when at least one second client searches at least one shared mail through the web browser 270, the search target is searched for a shared mail stored in the storage medium However, according to another embodiment of the present invention, the search target may be set to at least one search object including the shared mail search (e.g., &quot; integrated search &quot;).

If the shared mail corresponding to the search word input by the at least one second client does not exist in the shared mail search result (815) after the shared mail search as described above, 270 to the client terminal 260 of the at least one second client and outputs the shared mail search error message in operation 820.

On the other hand, if there is a shared mail corresponding to the search word input by the at least one second client in the shared mail search result (825), the search server transmits the shared mail through the web browser 270 A predetermined shared mail search result is transmitted to the client terminal 260 of the at least one second client and is output (830).

Referring to (B) of FIG. 9 according to a preferred embodiment of the present invention, the shared mail search result includes a mail title, contents, and file name and capacity of an attached file, It is preferable that the web browser 270 is transmitted to the client terminal 260 of at least one second client in accordance with the format. 9B, the shared mail search result uses the search result format of the general search server, but it is also possible to use a predetermined bulletin board format or a web mail format.

When the shared mail search result is transmitted to and outputted from the client terminal 260 of the at least one second client as described above, the search server receives the shared mail search result from the client terminal 260 of the at least one second client, (835) whether an access request for at least one shared mail among the shared mail is received.

If an access request for at least one shared mail among the shared mail included in the shared mail search result is received from the client terminal 260 of the at least one second client at operation 840, The second client checks 845 whether at least one or more preceding processes should be performed to access the shared mail for which the access is requested.

If at least one second client needs to perform at least one pre-process to access the shared mail (850), the mail server (200) transmits the pre-process to the at least one And the second client performs at least one pre-process for accessing the shared mail (855).

According to an embodiment of the present invention, in order for the at least one second client to access the shared mail, the client who has shared the shared mail must obtain the approval of the client. In this case, the search server performs a process of requesting the client to approve the at least one second client to access the shared mail.

For example, the search server may send a mail or a note to the client requesting the at least one or more second clients to approve the shared mail, or send a mail or a note to the mobile phone (e.g., a search server 200)) and the mobile phone number are registered), a message requesting approval of the at least one second client to access the shared mail may be transmitted. In the technical field of the present invention, The method of the present invention can be applied to various methods of implementing the shared mail access process through various methods other than the above-described embodiment. The technical idea of the present invention is that all types of shared messages It includes the method of approving access.

According to another embodiment of the present invention, in order for the at least one second client to access the shared mail, a predetermined amount is paid to the client sharing the shared mail. In this case, the search server performs a predetermined payment process for accessing the shared mail shared by the client by the at least one second client.

For example, the search server performs a predetermined process of paying a payment amount and / or a point corresponding to a predetermined share amount offered by the client from the at least one second client to the client. Those skilled in the art will be able to deduce various types of methods of sharing shared mail payment including credit card settlement, online deposit settlement, mobile phone settlement or point settlement, and the like, Includes a method of conducting all kinds of shared mail sharing settlement as described above.

At least one or more second clients have completed at least one preceding process for accessing the shared mail shared by the client through the above-described series of processes, or the at least one second client has received the shared mail The mail server 200 (or the search server) may allow remote access to the at least one shared mail requested by the at least one second client (step 860) To the at least one second client, the shared mail to which the access right is granted by the method defined by the mail server (200) and / or the client and / or the method requested by the at least one second client (865).
