Description

  The present invention relates to a device for delivering the same e-mail to a plurality of members registered in a mailing list, and is particularly effective as an emergency contact network for schools and PTA groups and companies, and uses a mobile terminal. This is related to a mailing list system that is easy for users to handle.

  In recent years, a mailing list by e-mail has begun to be used in place of a chained contact method by telephone in a class communication network in schools and the like, a PTA guardian communication network, and an emergency contact network in various organizations.

  A mailing list is a mechanism for sending and receiving broadcast mail between participants using an e-mail system, also called mass mail. As shown in Fig. 9, in the mailing list, when an email address for the mailing list is prepared and a participating member sends a message to that address, the sent message is automatically sent from the mailing list server to all members. Redelivered. Also, when a member replies to a message received from the mailing list, the reply message is also sent to the mailing list server and redistributed to all members from there.

A mailing list is known that has a mechanism for replying to emails to be delivered, and a function for receiving and summing up members' responses. In addition, there is also known a device having a group-by-group transmission function in which members are divided into groups and distributed only to members in the designated group.
However, these conventionally known answer counting functions and group-specific transmission functions only pursue the convenience of the distributor, and only increase the complexity for the user using the mobile phone.

In Japanese Patent No. 3691568 (Patent Document 1), in an e-mail management system having means for delivering the same e-mail to a plurality of members registered in a mailing list, a mailing list is created and a set-theoretical relationship between other mailing lists is disclosed. In response to a mailing list creation instructing means that designates and a mailing list creation instruction that specifies a set-theoretic relationship of other mailing lists, a new mailing list member set to be created is a set of member sets belonging to other mailing lists. An e-mail management system comprising a mailing list creation processing means determined by calculation is disclosed.
When there is a plurality of generated mailing lists, the e-mail management system automatically selects members registered in the mailing list by a set theory of members belonging to the generated mailing list. Registered.

Japanese Patent Laid-Open No. 2007-53502 (Patent Document 2) discloses a registration unit that registers a combination of mail addresses and a mail address associated with the combination in a storage unit, and transmission of an electronic mail requested for delivery. Search means for searching for a mail address associated with a combination of an original mail address and a destination mail address from the storage means, and a destination for adding the mail address searched by the search means to the destination of the electronic mail Disclosed is an e-mail transmission / reception apparatus including an adding unit.
This mail transmission / reception apparatus enables distribution by adding an external member or group as a distribution destination in addition to registered members of the mailing list.

JP 2005-522777 A (Patent Document 3) includes a step of receiving information on an organizational hierarchy, an identifier of at least an organizational hierarchy member from the received information, information on the status of the member in the organizational hierarchy, and e Disclosed is a method for performing e-mail communication using a mailing list, the method including a step of extracting information related to a mail address and a step of generating a plurality of mailing lists based on the extracted information.
In this method, members registered in a plurality of mailing lists can be automatically moved in conjunction with the organization chart.

  Each of the inventions described in Patent Documents 1 to 3 generates a plurality of mailing lists shown in FIG. 9 in order, and can function as an emergency contact network, apart from a communication tool in a company. Have difficulty. Further, it is not configured as a mailing list system that is easy to handle for users who use mobile terminals.

Japanese Patent No. 3691568 JP 2007-53502 A JP 2005-522777 Gazette

Although the mailing list is considered to be effective as a class communication network in schools, PTA guardian communication networks, and emergency communication networks in various organizations, the current mailing list system maintains and manages it. , And the succession of technology is difficult.
Therefore, the current situation is that the participation rate in the school-related communication network currently in operation is sluggish.

In addition, in a mailing list used as an emergency contact network in the event of a disaster, use of a personal computer is restricted, so it is necessary to rely on a mobile terminal such as a mobile phone. However, it has always been pointed out that a portable terminal with a small display screen has a problem that the operability of the mailing list, for example, how to join and cancel the mailing list is not easy.
Furthermore, when a mobile phone e-mail is used as a registered address, spam blocking is generally applied, so that generally more than 100 continuous e-mail transmissions are often rejected.

An object of the present invention is to provide an electronic mail distribution apparatus that is effective as an emergency contact network or the like and can construct a mailing list network that is easy for a user who uses a portable terminal to handle.
It is another object of the present invention to provide an electronic mail delivery apparatus that is excellent in operability and easy to maintain.

  The present invention provides an electronic mail distribution apparatus having means for distributing the same electronic mail to a plurality of members registered in a mailing list, and an ML address group of a unit group composed of a plurality of members, and the unit group ML address group. Means for generating all layered ML addresses by interrupting and distributing all of them, associating the transmission / reception direction between the unit group ML address group and all grouped ML addresses, and only for the specified mail address Means for restricting and setting the reception of the message.

The ML address generation means preferably further generates a selected distribution ML address for selecting, interrupting, and distributing a specific ML address in the unit group ML address group in a hierarchical manner.
It is preferable that the setting means further associates the transmission / reception direction between the unit group ML address group and the selected delivery ML address, and restricts the reception of the selected delivery ML address only to the designated mail address.

  According to the present invention, in an electronic mail delivery apparatus having means for delivering the same electronic mail to a plurality of members registered in a mailing list, an ML address group of a unit group composed of a plurality of members, and interrupting all of the ML address groups A means for selecting all the ML addresses to be distributed and a specific ML address in the unit group ML address group to generate an interrupt and a layer for generating the selected distribution ML addresses to be distributed; subordinate from the all ML addresses It is possible to transmit / receive to / from the unit group ML address group, and to associate the selected distribution ML address to the subordinate unit group ML address group to enable / disable transmission, and to the specified mail address only for the all-delivery ML address Specified and to be the same as or different from the above specification. Means for setting to limit the reception of said selection distribution ML address only the email address, is characterized in that it comprises a.

  The ML address generating means generates Header information and Footer information defined in the mail text, and sets the header information or Footer information addressed to all delivery ML addresses or selected delivery ML addresses that are interrupt delivery as units that are not interrupt delivery. It is preferably generated as a character / symbol different from the header information or footer information addressed to the group ML address group.

It is preferable that a part or all of the total distribution ML address, the selective distribution ML address, and the unit group ML address group are assigned as different domain names or different subdomain names.
It is preferable that a part or all of the unit group ML address group is assigned as a different domain name or a different subdomain name.

The mailing list network constructed by the electronic mail distribution apparatus according to the present invention is a class, club activities, PTA, and various groups as a contact network on a daily basis. Bundling, when an emergency contact event occurs, by sending a single e-mail to the mailing list address, it is possible to interrupt the contact network of the various groups and deliver the mail to all members of each group .
Further, by bundling a plurality of specific groups as a mailing list, it is possible to deliver mail to all members belonging to the group group.
While the mailing list network constructed by the electronic mail distribution apparatus of the present invention is extremely effective as an emergency contact network, it can be expected to greatly improve the mailing list participation rate.

Since the mailing list network of the present invention is constructed with hierarchies, a large number of people such as 10,000 people and 1 million people can be obtained by stacking the hierarchies with 99 hierarchies registered as one hierarchies for which continuous mail delivery on a mobile phone is not rejected. A mailing list network that can be urgently distributed to other members can be constructed.
In addition, as described above, an e-mail delivery apparatus capable of avoiding a spam block that a delivery e-mail that tends to occur particularly in a simultaneous e-mail using a mobile terminal does not reach and constructing a mailing list network using the mobile terminal As groundbreaking.

In addition, by assigning the mailing list address group of the unit group as different domain names or different subdomain names, a plurality of mailing list servers can be distributed and distributed to each member by distributing mail from each mailing list server. Distribution time can be greatly reduced.
Furthermore, the electronic mail delivery device of the present invention is excellent in operability and easy to maintain.

First, an overview of the mailing list of the present invention (hereinafter sometimes abbreviated as “ML”) will be described with reference to FIG.
FIG. 1 shows a service server 10 operated by a provider providing the mailing list service of the present invention, a network network (Internet network) 11 that anyone can connect to, and a service server 10 for accessing the mailing list service of the present invention. A setting terminal 13 for setting a mailing list address unique to the A organization 12 (hereinafter, abbreviated as “ML address”), and e-mail terminals 14, 14,... A setting terminal 13B for setting an ML address for a group B 12B, which is the same group as the group 12, and an access point 9 for the electronic mail terminals 14, 14,.

Each electronic mail terminal 14, 14,... Is illustrated as a portable terminal, but may be a personal computer or other electronic mail transmitting / receiving device.
A organization 12 (or B organization 12B, the same applies hereinafter) accesses service server 10 from its setting terminal 13 (or 13B, the same applies hereinafter), registers necessary items such as the organization name, responsible person, etc. Get configuration and operational authority.

  The organization 12 that has obtained the setting and operation authority of the ML address uses the MLID (mailing list ID) and password to display unit groups 15, 15,. ML address group (for group (1), group (2), group (3)), ML address that interrupts and distributes to all the ML address groups (hereinafter referred to as all distribution ML addresses), and The ML address group of the unit group is selected, interrupted, and the ML address to be distributed (hereinafter referred to as the selected distribution ML address) is generated by a simple operation. get. Here, the unit group 15, 15,... Refers to a group in which all members of the organization belong in some form, such as by school club activities or classes, divisions by companies, or circles. .

If the unit groups 15, 15,... Are generated and members are registered in the group, the mailing list can be started in each unit group 15 using the ML address. At this time, mutual distribution between the unit groups 15, 15,.
At this time, when an e-mail is sent from the permitted terminal 16 to which an e-mail address is designated for all distribution ML addresses, the e-mail is interrupted to the ML addresses of the unit groups 15, 15,. Delivered to everyone.
Similarly, when an e-mail is sent from the permitted terminal 17 designated with the mail address to the selected delivery ML address, the mail interrupts the ML address of the unit group 15, 15,. Delivered to all members in the unit group.

  In addition, when an e-mail is sent from the permitted terminal 16 to the all distribution ML addresses, the distribution is performed by the ML addresses of the unit groups 15, 15,... Under the all distribution ML addresses (group (1 ), Group (2), group (3) only, and ML group of unit groups 15B, 15B,... Of group B 13B (for group (4), group (5), group (6) for group (7)).

In addition, although the permission terminals 16 and 16B are illustrated as personal computer terminals, there is a possibility that the permission terminals 16 and 16B cannot be used at the time of a disaster.
All the ML addresses are operated by the mail server in the service server 10. Moreover, it is preferable that all distribution ML addresses are automatically allocated at the time of initial registration.

Next, the relationship among the ML addresses of the unit groups 15, 15,..., The selected distribution ML address, and the total distribution ML address will be described with reference to FIG.
8 shows an ML address group (hereinafter referred to as a unit group ML address group) 23 of the unit groups 15, 15,... Together with its members 14, 14,. The members 14, 14,... May all be different persons, or the same member may exist as long as the unit group 15 is exceeded. The unit group ML address group 23 is used on a daily basis within the unit group 15.

  The unit groups 15, 15,... Are preferably the smallest unit group in the organization that receives the mailing list service. In this case, the mailing list function does not stop at the contact means, but also functions as a communication tool within the group. Transmission / reception between the members 14 across the unit groups 15, 15,... Is not necessary, and transmission / reception between the members in the unit group 15 may be ensured.

In FIG. 8, the entire distribution ML address 25 is shown together with the sender's permission terminal 16 and its transmission destination 18. All the delivery ML addresses 25 are utilized non-daily in an emergency.
Further, in FIG. 8, the selective delivery ML address 24 is shown together with the sender's permission terminal 17 and its destination 19. The selective delivery ML address 24 is utilized semi-daily.
As described above, the present invention aims to facilitate maintenance management by hierarchizing ML address groups and automating settings such as generation and association of ML address groups.

Then, the structure of this invention is demonstrated in order.
FIG. 2 shows a personal computer screen when setting a mailing list in the present invention, in which a hierarchical ML address group is visualized and displayed, and a user who has no knowledge of mailing list generation can easily understand the correlation. It is a screen display that can be understood.
In the embodiment described below, a mailing list having three types of ML address groups including a unit group ML address group 23, a selected distribution ML address 24, and an all distribution ML address 25 will be described, but the selected distribution ML address 24 is not provided. Mailing lists are also within the scope of the present invention.

FIG. 2 shows the setting terminal 13, its setting screen 21, the group name 22 for setting, the ML address group 23 of the unit groups 15, 15,..., The selected distribution ML address 24, and the all distribution. ML address 25 is shown.
In FIG. 2, an arrow 26 indicates that an e-mail is distributed from all the distribution ML addresses 25 to the unit group ML address group 23, and an arrow 27 indicates that the selected distribution ML address 24 is transmitted to the unit group ML address group 23. Each is shown to deliver email. Reference numeral 28 denotes an add button for newly generating the selected distribution ML address 24, and reference numeral 29 denotes an add button for newly generating the unit group ML address 23.

In FIG. 2, an organization that intends to construct an emergency contact network or the like performs a predetermined registration procedure from a home page that provides the mailing list service of the present invention.
The registered organization accesses the setting screen 21 using a password or the like given by the business operator, and arbitrarily sets the three types of ML addresses. At that time, all the distribution ML addresses 25 set to only one for each organization may be newly generated on this screen 21 or may be assigned at the time of registration of the organization.

Next, the selection delivery ML address 24 (group) generation button 28 is operated to newly generate the selection delivery ML address 24. In this case, it is preferable to input only the user name in front of the @ mark of the address.
Next, an add button 29 is operated to generate a necessary number of unit group ML addresses 23 under the selected distribution ML address 24. At this time, for the unit group ML address 23, the transmission / reception relations of the selected distribution ML address 24 and the all distribution ML address 25 are automatically set.

  That is, as indicated by the arrow 27, the unit group ML address 23 group generated under one selected delivery ML address 24 is received only from the one selected delivery ML address 24, and from other selected delivery ML addresses 24. Will not receive. The transmission / reception direction between the selected distribution ML address 24 and the subordinate unit group ML address 23 groups is one direction from the selected distribution ML address 24 to the unit ML address 23 group side in this figure. Alternatively, bidirectional transmission / reception between both ML addresses may be performed, or the user may be able to select or change one-way transmission or bidirectional transmission / reception without fixing the direction setting. Further, the transmission / reception relationship between all distribution ML address 25 and unit group ML address 23 group is unidirectional transmission from all distribution ML address 25 to unit group ML address 23 group as indicated by arrow 26.

  The ML address groups 23, 24, and 25 generated in this way become ML addresses that can be used immediately by the service server 10. First, each unit group ML address 23 has an e-mail address of a member who uses it. Is registered, and a mailing list is constructed in each unit group. The unit group ML address 23 may be any one of two-way distribution between members, one-way distribution from a specific member, or a selection method capable of changing the direction setting.

  FIG. 3 is a flowchart showing a procedure for generating all distribution ML addresses 25. A mail server having a mailing list function on the left side and a mail server having a mailing list function on the right side (hereinafter referred to as an ML server) with the service server 10 in the center portion interposed therebetween 30) is arranged. The service server 10 and the ML server 30 will be described separately for convenience of explanation, but they may be physically the same server or different servers.

In relation to FIG. 2, the service server 10 works to generate all distribution ML addresses, and the ML setting screen 21 is displayed by the service server 10.
The service server 10 includes a registrant database (hereinafter referred to as “USDB”) 310 and an MLID database (hereinafter referred to as “MLDB”) 320.

The user who has completed the registration of the service provider inputs (321) any MLID from the terminal 13 in which the e-mail address is set, and makes an application. The service server 10 that has received this application (313), after confirming the registration in the USDB 310, queries the MLDB 320 and checks (314) whether the applied MLID does not overlap with the already registered MLID. If it does, the terminal 13 is requested to input another MLID again (322). If there is no overlap, the MLDB 320 is registered with the MLID 320 (315).
The MLDB 320 automatically generates (316) an ML address based on the MLID simultaneously with the end of the registration process (315), and the service server 10 additionally registers (341) the generated ML address with the ML server 30.

When the registration process (341) is completed, the service server 10 registers (318) the MLID in the user file (record) of the USDB 310, and the USDB 310 associates the MLID with the ML address (319). , The terminal 13 displays a reception end screen (323), and the process ends.
As a result of the above processing, an ML address that can be used by the user is set in the ML server 30, and a mailing list of an organization to which the user belongs is established on the ML server 30. The ML address set here becomes the all-delivery ML address 25 after the association processing described later.

Next, the generation procedure of the selective delivery ML address 24 will be described with reference to FIG. If the mailing list does not require generation of the selective delivery ML address 24, the process proceeds to the unit group ML address generation procedure shown in FIG.
As in FIG. 3, FIG. 4 also has a setting terminal 13 on the left side and an ML server 30 on the right side with the service server 10 in the center. In addition, in relation to FIG. 2, the service server 10 in this flowchart works to generate a selective delivery ML address.
That is, the user clicks the “G-Add” button 28 displayed on the setting screen 21 of FIG. 2 and inputs a new “selected delivery ML address” from the input operation screen of “selected delivery ML address” (not shown) (421) ) And send.

  The service server 10 that has received this input data confirms registration in the USDB 310 (413), and then queries the MLDB 320 to check whether it overlaps with the already registered ML address (414), and then with the “selected delivery ML address” data. From the received various data, “all distribution ML address” is confirmed (415), and “selected distribution ML address” is generated (416).

After registering (417) the various data in the USDB 310 and MLDB 320, the service server 10 newly registers (431) the selected delivery ML address together with the various data in the ML server 30.
The service server 10 receives the completion of the registration process of the ML server 30 (418), notifies the setting terminal 13 that the work has been completed (423), and ends.

Next, a procedure for generating a unit group ML address will be described with reference to FIG.
5 and FIG. 4, the setting terminal 13 is arranged on the left side and the ML server 30 is arranged on the right side with the service server 10 in the center portion interposed therebetween. Further, in the relationship with FIG. 2, the service server 10 of this flowchart works to generate a unit group ML address.
That is, by clicking the “unit ML-add” button 29 displayed on the setting screen 21 in FIG. 2, a new “unit group ML address” is input from the “unit group ML address” input operation screen (not shown) ( 531) and transmit.

The service server 10 that has received this input data confirms registration with the USDB 310 (513), and then queries the MLDB 320 to check whether it overlaps with the already registered ML address (514). From the received various data, related “all delivery ML address” and “selected delivery ML address” information is confirmed (515), and “unit group ML address” is generated (516).
Next, the service server 10 performs transmission / reception relation association processing (517) for each ML address. By this association processing, hierarchization as shown by arrows 26 and 27 in FIG. 2 is performed for each ML address. The hierarchy association process (517) will be described later.

After registering the various data in the USDB 310 and MLDB 320 (518), the service server 10 newly registers a unit group ML address together with the various data in the ML server 30 (541).
The service server 10 receives the completion of the registration process of the ML server 30 (519), and notifies the setting terminal 13 that the work has been completed (533).

Next, the service server 10 generates a registration-dedicated e-mail address for member registration (participation) in the unit group ML address (520), and registers it in the ML server 30 (521). As a result, the ML server 30 simply receives the mail addressed to the mail address, registers the mail sender's mail address in addition to the unit group ML address, and enables transmission / reception using the unit group ML address. Will be able to.
And monitoring means for monitoring the registration-dedicated e-mail address, and separating a sender's e-mail address from the e-mail when the e-mail for registration is received and adding it to the transmission / reception permitted e-mail address list of the unit group ML address. Set (522).
Further, like the member registration, the registrant address can be deleted (deregistration) simply by receiving an email (523, 524, 525).

  The member registration (deletion) process is made common to all unit group ML addresses in order to save hardware and software resources, and is distinguished by entering a command in the mail body or subject of the registration (deletion) mail. It can also be devised. However, as a member registration and deletion method, it is desirable to use a method of sending an e-mail in order to make the mailing list user aware of participation and withdrawal. In addition, for a device such as a mobile phone, which has anti-spam measures, this registration (deletion) method by sending an e-mail is preferable because the presence of the filter is noticed.

  In the flow of FIG. 5, the “generation and registration completion report” (519) of the unit group ML address by the service server 10 may be after “member deletion address monitoring setting” (525).

Next, the association process (517) described in FIG. 5 will be described in detail with reference to FIG.
In FIG. 6, the mutual transmission / reception relationship of the unit group ML address 23, the selected distribution ML address 24 and the all distribution ML address 25 is indicated by arrows 18 and 19.
That is, the unit group ML address 23 is set so that only reception from the selected distribution ML address 24 and the all distribution ML address 25 is permitted. However, depending on the use of the mailing list, the transmission / reception relationship may be changed to allow bidirectional transmission / reception.
The ML address is preferably one for all groups, one for each group, one for the selected distribution ML address, and two for the unit group ML address.

  The unit group ML address 23, the selected distribution ML address 24, and the all distribution ML address 25 are defined in the mail body information (separate from the header information 64 described later) 61 to 63 and 66, respectively. Header information 64, Footer information 65, transmission / reception permitted address list information 67 transmitted / received by each ML address, and other necessary information 68 are set.

Among each information, characters other than those unique to the organization and group are automatically set according to information predefined in the USDB 310 or MLDB 320.
That is, the To information 61, the From information 62, and the Reply-To information 66 are automatically executed with the definition of “rewrite and transmit to the corresponding ML address” from the viewpoint of protecting personal information of members.

The transmission / reception permitted address list information 67 of all distribution ML addresses 25 is set when the unit group ML address 23 is generated so as to be distributed to all the subordinate unit group ML addresses 23, and to all distribution ML addresses 25. Also set the e-mail address for sending. Similarly, the transmission / reception permitted address list information 67 of the selected distribution ML address 24 is also distributed to the selected subordinate unit group ML address 23 (ML addresses of the unit groups 15c and 15d shown in FIG. 8). As described above, it is set when the unit group ML address 23 is generated, and the transmission-permitted mail address to the selective distribution ML address 24 is also set.
The subject information 63, header information 64, and footer information 65 will be described below.

Next, a description will be given with reference to FIG. 7 which is an example of a screen in which the received mail from the mailing list of the present invention is displayed on the portable terminal.
A screen example 710 delivered to the unit group ML address 23 is shown in the upper half of FIG. 7, and a screen example 720 delivered from all the delivery ML addresses 25 to the unit group ML address is shown in the lower left part of FIG. 7. In the lower right part of FIG. 7, an example screen 730 distributed from the selected distribution ML address 24 to the unit group ML address is shown.

  In the screen examples 710, 720, and 730, the From information 62 is the sender address 712, 722, 732, and the To information 61 is the destination address 713, 723, on the outer upper part of the screen frames 711, 721, 731 provided in common. , 733, Subject information 63 is displayed as titles (subjects) 714, 724, 734, respectively.

  In FIG. 7, the sender address and the address address (712 and 713, 722 and 723, 732 and 733) are the same address, and the ML address of the corresponding group or group is hidden from the private address of the member. It is for protecting. The reason why the serial number is entered in the subject (subject) is to prevent mistakes in communication loss in the communication network.

  In addition, the mail text is displayed in each of the screen frames 711, 721, 731, the header information 64 is automatically inserted in the sentence heads 715, 725, 735, and the footer information 65 is automatically inserted in the sentence endings 717, 727, 737, respectively. The mail text transmitted by the member is displayed at 716, 726, and 736.

  The header information 64 is defined in the mail text, and by putting a unique character for group identification and a start mark, identification with mail other than ML becomes easy. In addition, Footer information 65 is also defined in the mail text, and it is preferable to put an end mark as a countermeasure such as character restriction of e-mail by a mobile phone. By inserting the end mark, it becomes easy to detect deletion of a transmitted sentence due to the limitation of the number of characters like an e-mail of a mobile phone.

Further, in screen example 720, upper character group (Header information) 728 and lower character group (Footer information) 729 that are automatically inserted at the time of transmission to all distribution ML addresses are displayed. Further, in the screen example 730, an upper character group (Header information) 738 and a lower character group (Footer information) 739 that are automatically inserted at the time of transmission to the selected distribution ML address are displayed.
These upper character groups 728 and 738 and lower character groups 729 and 739 also have the same role as the header information 64 and the footer information 65 described above, but the header information 64 or footer addressed to the unit group ML address that is not interrupted. By using different characters / symbols from the information 65, in addition to the above-mentioned role, there is an effect of prompting the user to view the mail text with caution.

  In the electronic mail delivery apparatus of the present invention, the unit group ML address group 23 is not assigned as an ML address group having the same domain name or the same subdomain name as shown in FIG. 2, but different domain names or different subdomains. It can be assigned as a group of ML addresses having names. In this way, a plurality of ML servers 30 are distributed and installed for every delivery ML address, selected delivery ML address, and unit group ML address, and mail delivery is performed in parallel from each ML server 30. Delivery time to all members is greatly reduced.

For example, if there are 200 unit groups 15, 15,... And 50 e-mail terminals 14, 14,... In each unit group 15, 15,. There will be registration of the e-mail terminals 14, 14,. At this time, when the delivery processing capacity of the ML server 30 is set to 4 / second, the case of simultaneous delivery to all terminals is calculated.
If it is distributed simultaneously by a conventional mailing list network, it takes about 42 minutes at 10000 ÷ 4 ÷ 60 (minutes / seconds). This is because in the conventional mailing list network, a plurality of ML servers 30 cannot be installed in a distributed manner and distributed at the same time, and the processing is sequentially performed by one ML server 30.

On the other hand, according to the mailing list network of the present invention, here, if 200 unit group ML address groups 23 are equally distributed and acquired by 10 ML servers 30 by 20 unit group ML address groups 23, It is calculated as follows.
(1) First, the distribution time of all distribution ML addresses 25 → unit group ML address group 23 (200 addresses) is 200 ÷ 4 = 50 seconds.
(2) Next, the distribution time of the unit group ML address group 23 → the members in the group is calculated as (50 ÷ 4) × 20 ÷ 60 (minute / second), which takes about 4 minutes. Here, since the remaining nine ML servers 30 are also distributed, they can be distributed within the same time.
Therefore, the total time of (1) + (2) is about 4 minutes and 50 seconds, and the delivery time is greatly shortened.
Further, the effect of shortening the distribution time can be obtained even if the ML server 30 of all distribution ML addresses or the selected distribution ML address and the ML server 30 of the unit group ML address are independent.

As described above, the all-delivery ML address 25 (or the selected delivery ML address 24) and the subordinate unit group ML address group 23 have been described in the embodiment of the two-layer mailing list. However, under the unit group ML address group 23, It is also within the scope of the present invention to form a mailing list having three or more layers by forming a group of subdivided ML addresses.
