In particular, in recent years, the use of group mail in relation to work is increasing. Group mail is mail sent to a plurality of users belonging to a specific group. When a user designates a specific group as a mail recipient, the mail is sent to all users belonging to the group. The mail address information for the users belonging to the group is set in advance by the mail sender.

Such group mails can be used, for example, to discuss matters such as the company's proposal, and discussions are generally conducted in a manner of making a full reply to the recipients of the group mail.

In addition, group mails are frequently used even when they are not used for work, but also collect opinions from members in the community.

Since such group mails are generally replyed to in large numbers, users must check the group mails sent in large numbers in order to know the history of the group mails. In particular, in the case of group mails transmitted over a large number of users, it is difficult for a user to check to what extent the group mails have been read. In order to check the contents of the group mails, the user has to check the entire group mails manually. There was this.

The group mail server converts the unread portion of the group to be displayed in a different color.

According to another aspect of the present invention, when the mail written by the user is a group mail, the group mail ID setting unit for receiving the group mail and setting the group mail ID and the group mail sequence ID in the received group mail-the group mail ID is An ID assigned to a plurality of group mails returned in a plurality, wherein the group mail sequence ID is an ID for identifying an order of each group mail returned in a plurality; A group mail storage unit for storing the mail in which the group mail ID and the group mail sequence ID are set by the group mail ID setting unit; When receiving the group mail, the group mail reception confirmation unit having the same group mail ID as the received group mail and requesting the mail system to receive the mail read status of the group mail users for the group mails having different group mail sequence IDs; And a group mail conversion unit for converting group mail data for each recipient based on the mail read status information for each recipient provided by the group mail reception confirmation unit and transmitting the group mail data to the mail system.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the group mail management system and method according to the present invention.

1 is a diagram showing the configuration of a group mail management system according to an embodiment of the present invention.

Referring to FIG. 1, a mail management system according to an embodiment of the present invention includes a mail web server 100, a mail server 102, a mail box 104, a group mail server 106, and a group mail database 108. And a user client 110 communicating with the mail management system.

In FIG. 1, a user user 110 is provided with a mail user agent (MUA). MUA is a client program used by a user to send and receive e-mail. MUA can include Microsoft's Outlook Express, Netscape's Netscape, and Unix-like / usr / ucb / mail. The present invention mainly applies to webmail, in which case the web browser plays the role of MUA. However, since the web browser alone cannot perform the MIME format generation and the SMTP protocol communication for the communication with the mail server, the web browser and the mail web server 100 serve as MUAs together.

The user client 110 may include both a general PC and a device capable of communicating with and processing digital data by being connected to a network such as a notebook, a mobile phone, a personal digital assistant (PDA), and the like. In addition, the network may include both a wired network such as an internet network and a private network, as well as a wireless network such as a mobile communication network and a wireless internet network.

The mail web server 100 transmits a web page related to mail to the user client 110 so that the user can use the webmail service, and communicates with the mail server 102 when the user requests to send or view the mail. Through the user's request information processing.

The mail web server 100 transmits various types of mail-related web pages, such as a mail list, a mail body, and a mail write, to the user client 100 according to a user's request, and the MUA of the user client is transmitted from the mail web server 100. Display the web page being sent.

In addition, when the mail web server 100 receives a mail transmission request from the user client 110, the mail web server 100 generates mail data in a MIME format by using mail data transmitted from the user client, and the mail server 102 generates the generated MIME format. To be sent).

The present invention relates to group mail, and according to an embodiment of the present invention, the mail web server 100 provides a separate mail writing page for group mail. As a mail addressed to a plurality of users belonging to a preset group group mail, the mail web server 100 may provide a separate web page for writing a group mail. When a user creates a group mail using the group mail write page provided by the mail web server, the created group mail data is transmitted to the group mail management server 106.

According to another embodiment of the present invention, the mail web server 100 may provide a mail writing page including a script for determining whether the mail transmitted by the user is a group mail or a general mail. The script included in the mail writing page determines whether the mail written by the user is a normal mail or a group mail, and if the mail is a group mail, sends the mail to the group mail server.

The mail server 102 receives the user's request information from the mail web server 100 and processes the user's request information related to the mail. When a mail is delivered to a mail account of a specific user like a general mail server, a mail server stores the mail in a mailbox, and when a user requests a mail transmission using a mail writing page provided by a mail web server, Sends mail to the mail address.

The mail box 104 is a database for storing electronic mail, and stores mail data of a MIME type. When the acknowledgment function is provided, the mailbox 104 may additionally store information on whether the recipient has browsed a specific mail.

The group mail server 106 functions to receive and store the group mail sent by the user when the user sends the group mail. In addition, the group mail server 106 performs a predetermined conversion operation on the received group mail and then provides the converted group mail to the mail web server 100.

A group mail is mail sent to a plurality of users belonging to a specific group as recipients. For example, the group mail may be a group mail addressed to business colleagues or a group mail addressed to a school alumni. Users can set a plurality of users as a specific group by using an address book, and when the group is a recipient, mail is sent to a plurality of users belonging to the group. However, the present invention is limited to the case where the user arbitrarily sets a specific group as a recipient, and the present invention may be applied to a group mail even when sending a mail to a plurality of recipients. will be.

Typically, when a user sends a group mail to a plurality of recipients, the members of the group exchange opinions by replying to the whole. For example, if you send a group mail to your coworkers about an advertising plan, the coworkers suggest the plan by sending a full reply. Therefore, group mails are generally replied many times.

In the related art, when a group mail is replied in several times, it is difficult for the user to check whether the group mail is read up to what level, and in the end, there is a problem in which all the group mails returned are checked. For example, when a group mail is returned all over 10 times, there is a problem in which the user has to read 10 group mails in order to check up to what level.

The present invention is provided with a separate group mail management server 106, in order to eliminate the user's hassle, the group mail management server 106 is to determine what level of group mail each user reads when sending group mail The group mail is converted to display information about the group mail, and the converted group mail is transmitted for each user. Therefore, the user can check whether the mail is read up to what level even if only the most recent group mail is read. For example, the group mail management server 106 may change the group mail so that the part read by the user and the part unread by the user are displayed in different colors. It will be apparent to those skilled in the art that various methods for visually identifying the read and unread parts may be used in addition to the case of displaying in different colors.

In addition, the group mail management server 106 stores group mails which are sequentially returned in the group mail database 108 and manages the stored group mails. A method of managing the group mail transmitted from the user client 100 and converting the group mail for each user will be described in detail with reference to a separate drawing.

2 is a block diagram showing the module configuration of a mail web server according to an embodiment of the present invention.

2, a mail web server according to an embodiment of the present invention includes a client communication unit 200, a mail web page generation unit 202, a group mail server communication unit 204, a MIME generation unit 206, and a control unit ( 208 and the mail server communication unit 210.

The client communication unit 200 receives the request information from the user client and provides the information requested by the client. For example, when a user requests a mail list web page, the user's request information is transmitted to the client communication unit 200 of the mail server, and the mail web server transmits the mail list page to the client through the client communication unit 200. . The client communication unit 200 may communicate with a user client through a general HTTP protocol.

The mail web page generator 202 functions to generate various kinds of mail web pages provided through a mail web server. For example, the webpage generation unit 202 generates mail-related webpages such as a mail list view page, a mail body view page, a mail write page, a group mail write page, and provide the same to a user client through the client communication unit 200. do.

As described above, the mail web page generation unit 202 may generate a separate group mail writing page for creating a group mail, and includes a script for determining whether the mail written by the user is a group mail or a general mail. You can also create a mail writing page.

The group mail server communication unit 204 functions to receive the converted group mail transmitted from the group mail server and provide it to the mail server 102. The group mail sent from the user client to the group mail management server 106 is converted for each recipient, and the group mail server communication unit 204 receives the converted mail and provides it to the MIME generation unit 206.

In addition, according to the embodiment, the mail web server 100 may assign a mail ID to the group mail provided from the group mail management server 106. When the mail ID is assigned, the group mail server communication unit 204 may send a group mail. Mail ID information is transmitted to the group mail server 106.

The MIME generation unit 206 converts the electronic mail data into MIME format data when the user requests an electronic mail transmission through a mail writing page or the like. Since the MIME data format is already known, a detailed description thereof will be omitted. When the group mail server communication unit 204 receives the group mail provided from the group mail server 106, the group mail server communication unit 204 forwards the received group mail to the MIME generating unit 206, and generates MIME. The unit 206 converts the group mail into data of the MIME format.

The controller 208 controls the overall operation of the mail web server. For example, when the group mail is provided from the group mail server 106, the control unit 208 transmits the request information to the MIME generating unit and sends the request information to the mail web when the user requests a web page for creating the group mail. Controls actions such as passing to the page.

The mail server communication unit 204 functions to transmit the mail data of the MIME format generated by the MIME generation unit 202 to the mail server. The mail server communication unit may transmit the data of the MIME format through the SMTP protocol which is a transmission protocol related to mail.

3 is a block diagram showing a module configuration of a mail server according to an embodiment of the present invention.

Referring to FIG. 3, a mail server according to an embodiment of the present invention may include an MTA 300, an MDA 302, and an MRA 304.

The Mail Transfer Agent (MTA) 300 receives e-mail from a mail web server or other mail server via the SMTP communication protocol and calls the MDA 302 to send the received e-mail to a mail box of the MTA or mail server of another mail server. Function to pass on. In general, send mail and qmail may be used as the MTA.

The MDA (Mail Delivery Agent) 302 is an agent program module that delivers an e-mail received by an MTA to an actual user. The MDA is generally divided into an external delivery and an internal delivery. In case of external transmission, each MDA exists according to channel (TCP, uucp, etc.). In case of Unix, it can be driven by / bin / sh.

In the case of internal delivery, the MTA that delivers the mail received by the MTA to the user's mailbox is referred to as a local MDA. Typically, a local MDA delivers e-mail information to a mailbox on the local file system, using a filtering program that can process the e-mail. The local MDA performs MIME (Multipurpose Internet Mail Extension) parsing when storing e-mail in a mailbox. This means parsing data to be stored in a mailbox from MIME type mail data.

If the mail delivered from the MTA is delivered internally, the MDA delivers the mail to the mailbox. The MDA may transmit a part or information of the header information of the mail to the mail index server, and a separate module for delivering the mail header information to the mail index server may be provided.

Mail Retrieval Agent (MRA) 304 is a program that allows a user to access to check e-mail from outside, and includes POP3 DEAMON and IMAP4 DEAMON.

4 is a block diagram showing the module configuration of a group mail server according to an embodiment of the present invention.

Referring to FIG. 4, a group mail ID setting unit 400, a group mail storage unit 402, a group mail reception confirmation unit 404, and a group mail conversion unit 406 according to an embodiment of the present invention may be included. Can be.

The group mail ID setting unit 400 functions to set the ID of the group mail and the sequence ID of the group mail when the group mail is transmitted from the user client.

If the mail sent from the user client is the first group mail, the group mail ID setting unit sets the group mail ID for the group mail. The reply mail for the first group mail includes the information on the original mail in the MIME format, so there is no need to set the group mail ID.

In addition, the group mail ID setting unit 400 sets a sequence ID for each group mail in order to identify the group mail returned multiple times. For example, the group mail ID setting unit 400 sets sequence ID 1 for the first group mail and sequence ID 2 for the first group mail to which the group mail is first returned.

That is, the group mail ID setting unit 400 determines whether the mail transmitted from the user client is the first group mail or the reply mail, sets the group mail ID and sequence number in the case of the first mail, and returns the reply mail. In this case, it determines the number of replies and sets the sequence number.

The group mail storage unit 402 stores the group mail in which the group mail ID and the group mail sequence ID are set by the group mail ID setting unit 400 in the group mail database.

The group mail storage unit 402 stores the group mail transmitted from the user client in a separate field for each group mail having the same group mail ID in the group mail database. Group mails having the same group mail ID are sequentially stored in the group mail database according to the sequence ID. That is, the group mail storage unit 402 stores group mails as a kind of bulletin board.

5 is a diagram illustrating a field configuration of a group mail database according to an embodiment of the present invention.

Referring to FIG. 5, the group mail database may include a group mail ID field 500, a group mail sequence ID field 502, a mail ID field 504, a mail index field 506, and a mail body field 508. Can be.

The group mail ID 500 and the group mail sequence ID 502 are information set by the group mail ID setting unit described above.

The mail index 506 means header information of a mail such as a sender, a subject, a recipient, and a date of the mail, and means body data of the mail of the mail body 508.

The mail ID is an ID for uniquely identifying the mail for both the group mail and the general mail other than the group mail. The mail ID may or may not be stored in the group mail database according to an embodiment.

According to an embodiment, the mail ID may be used to check whether a group mail has been received, which will be described later in detail.

The group mail data stored in the group mail database is used for group mail conversion.

The group mail reception confirmation unit 404 functions to check whether the recipient has read the transmitted group mail. Specifically, the group mail reception confirmation unit 404 checks whether or not the group mail returned by the user corresponding to the group mail recipient has been read up to several times of the group mails.

The group mail reception confirmation unit 404 checks up to which group mail each recipient of the group mail reads through a communication with a mail server or a mailbox. When users read a group mail, the group mail read information is recorded in a mailbox. Checking whether the user has read a specific mail and recording it in a mailbox is a known general technique, and thus a detailed description thereof will be omitted.

According to an embodiment of the present invention, the group mail reception confirmation unit 404 may check the mail read status of the group mail recipients at the time when the group mail is transmitted from the user client and the group mail is converted.

According to another embodiment of the present invention, the group mail reception confirmation unit 404 may check the mail read status of the group mail recipients at predetermined time intervals.

In order for the group mail reception confirmation unit 404 to check the mail read status of the group mail recipients, according to an embodiment of the present invention, the mailbox stores the group mail ID and the group mail sequence ID information together with general MIME information. .

In this case, the group mail receipt confirmation unit 404 forwards the group mail receipt request information including the group mail ID, the group mail sequence ID, and the group mail recipient information to the mail server, and the mail server confirms the group mail receipt request. Provide information to the mailbox. The mailbox checks whether the group mail recipient included in the group mail receipt request information has been read by the group mail ID and the group mail sequence ID included in the group mail receipt request information. To provide.

The above-described embodiment may be implemented when the mailbox changes the existing storage method and additionally stores the group mail ID and the group mail sequence ID information. According to another embodiment of the present invention, the group mail server manages the mail ID information in the mailbox of each group mail and delivers the group mail receipt request information including the mail ID and the recipient information of the mail to the mail server. You can also request confirmation of receipt of mail.

The mailbox checks whether or not the mail corresponding to the mail ID included in the group mail receipt request information has been read by the recipient included in the group mail receipt request information and provides the confirmation information to the mail server.

Typically, since the mail ID is given by the mail web server or mail server, the group mail server provides the group mail received from the user client to the mail web server, and then the mail ID of the group mail provided from the mail web server or mail server. Can be received and stored in association with the group mail ID and the group mail sequence ID.

When a mail ID is given using parameter information of mail such as a mail recipient and a date, the group mail server may directly assign a mail ID without receiving mail ID information from a mail web server or a mail server.

When the group mail receipt confirming unit 404 confirms whether or not the group mail received by each recipient of the group mail has been read up to several times of the group mails returned by the above-described method, the group mail receipt confirming unit 404 confirms. The information is provided to the group mail conversion unit 406, and the group mail conversion unit 406 converts the group mail for each group mail recipient based on the confirmation information.

For example, if the group mail is replyed ten times and it is confirmed that recipient A of the group mail recipients has read only the fifth reply mail, the group mail conversion unit 406 returns the sixth reply in the group mail to be provided to the recipient A. Convert the group mail so that the contents of the mail to the tenth reply mail are displayed in different colors. In addition, when it is confirmed that the recipient B among the group mail recipients has read only the eighth reply mail, the group mail conversion unit 406 has different contents from the ninth reply mail to the tenth reply mail in the group mail to be provided to the recipient B. Convert group mail to be colored.

As described above, it will be apparent to those skilled in the art that various visual display methods may be used to distinguish between read and unread mail in addition to displaying the color differently.

The group mail converted for each recipient by the group mail conversion unit 406 is transmitted to the mail web server 100, and the mail web server performs a general MIME conversion operation.

Although the group mail sent from the user client is converted for each recipient by the group mail server, it is preferable that each converted group mail has the same group mail ID, group mail sequence ID, and mail ID for management convenience.

6 is a flowchart illustrating a process of storing and delivering a group mail to a group mail server according to an exemplary embodiment of the present invention.

Referring to FIG. 6, the user client determines whether the mail requested by the user is a group mail through the script of the mail writing page (step 600). As described above, the determination as to whether or not it is a group mail may vary depending on the operator's setting. According to an embodiment of the present invention, it may be determined as a group mail when a user directly designates a group mail through a predetermined interface or designates a group on a preset address book as a recipient. Alternatively, if the number of mail recipients is more than a predetermined number, it may be determined as a group mail.

If it is not a group mail, the mail requested by the user is delivered to the mail web server, and a general mail transmission procedure is performed (step 602).

If the mail requested by the user is a group mail, the mail data is sent to the group mail server instead of the mail web server (step 604).

The group mail server determines whether the transmitted mail is a reply mail of the group mail created by another user or the first group mail (step 606). In the case of the reply mail, since the mail data includes the information of the original mail, it is possible to determine whether it is the first group mail depending on whether the information of the original mail is included.

If the mail sent from the user client is the first group mail, the group mail server assigns a group mail ID. Since the reply mail to the first group mail is managed by the same group mail ID, the separate group mail ID granting procedure is not performed, and only the group mail sequence ID is assigned (step 610).

If a group mail ID and a group mail sequence ID for the group mail sent from the user client are given, the sent group mail is stored in the group mail database (step 612). As described above, the group mail sent from the user client may be stored in the form of a post in the sequence ID order.

7 is a flowchart illustrating a process of converting a group mail transmitted from a user client by a group mail server according to an exemplary embodiment of the present invention.

Referring to FIG. 7, after the group mail server stores the group mail by the procedure of FIG. 6, the group mail server determines whether there is a reply message before the stored group mail, and sends the group mail recipient's mail to the previously reply mail. Request the read status to the mail server (step 700).

For example, if the group ID sent from the user's client is stored and the group mail recipient is 5 and the group mail recipient is 5, the group mail server reads each group mail recipient's mail for messages with the group mail sequence ID 1-4. Ask the mail server for status.

If the group mail transmitted from the user's client is the first group mail (sequence ID 1), the mail server does not request the read status of the group mail recipients.

The mail server uses the information in the mailbox to provide the group mail server with information about how many recipients of the group mail have been read (step 702), and the group mail server uses the information from the mail server. To determine the number of group mails each group mail recipient has read (step 704).

Based on the information determined in step 704, the group mail server converts the group mail data for each recipient (step 706). As described above, a method of changing the color of the mail text of the unread portion for each recipient and other visual discrimination methods may be used.

The group mail data converted for each recipient is transmitted to the mail web server, and the mail web server performs a mail transmission procedure for the transmitted mail (step 708).

As described above, according to the group mail management system and method according to the preferred embodiment of the present invention, the group mail is managed separately through a separate group mail server, and the mail read status of the group mail recipients is checked to convert differently for each recipient. In addition, through mail conversion, the user can easily grasp the part he / she has read and the part that is not to be read even if the user does not check the history of the group mail replied to many times.
