[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a conventional mail transmitting / receiving apparatus. The user of the conventional mail transmitting / receiving apparatus is a mail service provider (mail server 200,
300, 400, etc.) and the terminal device 10,
11, 30 and the mobile terminal device 40 transmit and receive mails. The mail servers 200, 300, 400
It is connected to a communication line 80 (for example, the Internet). The terminal devices 10 and 11 communicate with a communication line 90 (for example,
It is connected to the mail server 200 via a public line. The terminal device 30 is connected to the mail server 30 via the communication line 90.
0, and the mobile terminal device 40 is connected to the mail server 400 via a wireless line.

The mail servers 200 and 300 have a function of receiving a mail via the communication line 80 or the communication line 90 and a function of transmitting a mail via the communication line 80 or the communication line 90. Further, the mail server 400 has a function of receiving mail via the communication line 80 or a wireless line, and a function of transmitting mail via the communication line 80 or a wireless line. Each mail server receives the mail at the receiving portion of the respective mail server (in the example of FIG. 1, the left side of each mail server), and when transmitting the mail, the mail server transmits the mail. In the example of 1, the mail is transmitted from the right side of each mail server. In the example of FIG. 1, the receiving part and the transmitting part are described separately for explanation, and the structure of the actual mail server is not limited.

For example, the mail server 300 is provided with a mail receiving area 305 (mail box or the like) for use by the recipient C using the terminal device 30. The mail delivered to the mail receiving area 305 is sent to the terminal device 3
When 0 is accessed using the user identification information (for example, ID and password), it is transmitted from the mail server 300 to the terminal device 30. Also, for example, the mail server 4
00, a mail receiving area 405 (a mail box or the like) for use by the recipient D using the portable terminal device 40 is provided. The mail delivered to the mail receiving area 405 is immediately transmitted from the mail server 400 to the mobile terminal device 40 if the mobile terminal device 40 can receive the mail without accessing the mobile terminal device 40.

For example, when the sender A sends the mail A to the recipient C, the sender A uses the terminal device 10 to send the user identification information (for example, I
D, password) and mail A are transmitted. When the mail server 200 receives the user identification information and the mail transmission request signal including the mail A from the terminal device 10, the mail server 200 sends the signal to the recipient mail address included in the mail A (in this case, the recipient mail of the recipient C). The mail A is transmitted to the mail server 300 including the address via the communication line 80. The mail server 300 receives the mail A transmitted from the mail server 200, recognizes that the mail is addressed to the recipient C, and stores (sends) the mail A in the mail receiving area 305. Then, the receiver C transmits a mail reception request signal including the user identification information (for example, ID and password) to the mail server 300 using the terminal device 30. When receiving the mail reception request signal from terminal device 30, mail server 300 transmits mail A stored in mail reception area 305 to terminal device 30.

For example, when the sender B sends the mail B to the receiver D, the sender B sends the mail B to the terminal device 1.
1, a mail transmission request signal including the user identification information (for example, ID and password) and the mail B is transmitted to the mail server 200. When the mail server 200 receives the user identification information and the mail transmission request signal including the mail B from the terminal device 11, the mail server 200 sends the mail transmission request signal to the receiver mail address included in the mail B (in this case, the receiver mail of the receiver D). The mail B is transmitted to the mail server 400 including the address via the communication line 80. Mail server 40
0 receives the mail B transmitted from the mail server 200, recognizes that the mail is addressed to the receiver D, and stores (sends) the mail B in the mail receiving area 405, and immediately transmits the mail B to the portable terminal device 40. Send mail B. Recipient D
Receives the mail B transmitted by the sender B without performing the mail receiving operation (regardless of time and place). As described above, in the conventional mail transmission / reception device, the mail addressed to the recipient is transmitted to the recipient irrespective of the time and place, that is, regardless of the intention of the recipient.

Next, FIG. 2 shows a schematic configuration diagram of an embodiment of the mail transmitting / receiving apparatus of the present invention. In FIG. 2, a proxy server 100 is added to the mail transmitting / receiving device of FIG. In the present embodiment, mail servers 200 to 400
When receiving mails from the terminal devices 10, 11, 30, and 40, the received mails are transmitted even if the mail server corresponding to the recipient mail address included in the mails is the mail server 200 to 400 or the like. , Is always set to be transmitted to the proxy server 100. In addition, when the mail servers 200 to 400 receive mail from the proxy server 100 (when receiving mail addressed to a recipient mail address managed by themselves), the received mail is included in the mail. Store (send) in the mail receiving area corresponding to the recipient mail address. Upon receiving the mail from the mail servers 200 to 400, the proxy server 100 determines whether a transmission condition (also a reception condition) corresponding to the received mail is satisfied, and when the transmission condition is satisfied, The received mail is transmitted to the mail servers 200 to 400 corresponding to the recipient mail addresses included in the received mail. These functions are provided in the transmission condition determination function 102.

For example, when the mail server 200 receives the mail A addressed to the receiver C and the mail B addressed to the receiver D transmitted from the terminal devices 10 and 11, the mail server 200 corresponds to the mail address of the receiver C Is the mail server 30
0, and even if the mail server corresponding to the mail address of the receiver D is the mail server 400, the mail A and the mail B are once transmitted to the proxy server 100. The proxy server 100 receives the mail A received from the mail server 200,
The mail B is transmitted to the mail server 300 and the mail server 400. Here, the proxy server 100 transmits transmission condition information (reception condition information) 100 in which transmission conditions (reception conditions) are set corresponding to each recipient (recipient mail address).
a. The transmission condition information (reception condition information) is stored in, for example, a storage device. Then, whether or not the transmission condition of the mail received from the mail server 200 is satisfied is determined based on the transmission condition corresponding to the recipient mail address included in the received mail, which is set in the transmission condition information. Judgment is made, and if the transmission conditions are satisfied, the received mail is transmitted to the mail servers 200 to 400. If the transmission condition of the mail is not satisfied, the mail is temporarily stored in the proxy server 100 and is transmitted when the transmission condition is satisfied. The transmission condition determination and retransmission processing and the like are provided in the proxy server 100 as the transmission condition determination function 102. Further, the proxy server 100 may have a transmission condition determination server and a retransmission processing server separately. In FIG. 2, the transmission condition set for the recipient C is satisfied for the mail A, and the transmission condition set for the recipient D is satisfied for the mail B. Not shown.

Next, referring to FIG. 3, transmission condition information 100
The setting contents of a will be described. Transmission condition information 100a
Are stored in a storage device accessible from the proxy server 100. The location of the storage device is the proxy server 10
If it is accessible from 0, it can be anywhere. Here, the setting of the content of the transmission condition information 100a can be set by each receiver. A specific method of the setting will be described later.

Next, each setting item of the transmission condition information 100a will be described. The e-mail address of each user is set in the recipient e-mail address. Proxy server 1
00 receives the mail including the recipient mail address that matches the recipient mail address stored in the transmission condition information 100a, and checks the transmission condition. When an e-mail having no recipient e-mail address that matches the recipient e-mail address stored in the transmission condition information 100a is received, the e-mail is transmitted to a mail server corresponding to the recipient e-mail address as it is (in this case, the conventional e-mail server). It works the same as a mail server). The recipient ID and the recipient password are identification information of the proxy server user, and are used to identify each user of the proxy server 100. As the identification information of the proxy server user, only the recipient ID may be used, or only the recipient password may be used, and various information can be used as long as the content can identify the user. . The recipient ID and recipient password are
When the user newly sets (registers) the transmission condition information 100a or changes the contents of the transmission condition information 100a, the user is specified (for example, the setting contents are illegally changed by a third party, etc.). Used to prevent that.

In FIG. 3, three items can be set as the transmission condition. The first is the acceptance condition. When the proxy server 100 receives an e-mail addressed to the recipient e-mail address for which the acceptance condition is set to “acceptable”, it checks other transmission conditions (in this case, the transmission time zone and the transmission day). If the other transmission conditions are satisfied, the e-mail is transmitted. If the other transmission conditions are not satisfied, the e-mail is not transmitted and is temporarily stored in the proxy server 100. Further, when the proxy server 100 receives a mail addressed to a recipient mail address for which the acceptance condition is set to “pause”, the proxy server 100 discards the mail without transmitting it. At this time,
It is also possible to notify the sender of the discarded mail by mail that the discarded mail has been discarded without being sent.
The second is a transmission time zone. In the transmission time zone, a time zone in which the user receives mail is set. For example, the user does not want to receive an email in the early morning and late at night,
If the user wishes to receive the mail only in the time zone of ２０20: 00, “9:00 to 20:00” is set in the transmission time zone. The third is a transmission day. As the transmission day, a day on which the user may receive the mail is set. For example,
If the user does not want to receive the mail on Friday, Saturday and Sunday, “Monday, Tuesday and Wednesday” is set on the transmission day.

The transfer destination mail address includes the proxy server 1
When the received mail is transmitted at 00, the mail address of the transfer destination to which the mail is transferred is set. For example, when the user cannot use the e-mail address that he or she normally uses due to a business trip or a trip, a mail address (e.g., a mail address of a portable terminal device) that can be used on a business trip or a destination is set. When the forwarding mail address is set, when the received mail satisfies the transmission conditions, the proxy server 100 transmits the mail when the received mail satisfies the transmission conditions. The message is transmitted to the transfer destination e-mail address set in 100a. Here, the transfer process is also included in the concept of transmitting to the terminal device corresponding to the recipient mail address.

Next, retransmission processing of a mail that does not satisfy the transmission conditions will be described using the standby information 100c shown in FIG. If the received mail satisfies the transmission condition, the proxy server 100 transmits the mail to a destination mail address (recipient mail address). On the other hand, if the received mail does not satisfy the transmission condition, the mail is temporarily held until the transmission condition is satisfied. In this case, for the temporarily held mail, the waiting information 10
0c. In the standby information 100c, information on the held mail is prepared. When the proxy server 100 holds the mail that does not satisfy the transmission condition, the proxy server 100 stores information about the mail together with the mail in the standby information 100c. And the proxy server 1
00 determines the transmission condition corresponding to the recipient mail address stored in the standby information 100c when determining whether or not the held mail can be transmitted. As a result of the confirmation, if the transmission condition is satisfied, the mail is transmitted to a predetermined destination mail address (recipient mail address or transfer destination mail address). (Retransmission processing)

Next, each item stored in the standby information 100c will be described with reference to FIG. The recipient mail address stores the recipient mail address of the mail held without satisfying the transmission conditions (hereinafter, referred to as held mail). This recipient e-mail address is used to confirm the transmission condition corresponding to the recipient e-mail address stored in the transmission condition information 100a when determining whether or not transmission is possible. Also, in the received mail,
If there are multiple recipient e-mail addresses and the transmission conditions corresponding to some recipient e-mail addresses are not satisfied and the transmission conditions corresponding to other recipient e-mail addresses are satisfied, Of the recipient e-mail addresses included in the received e-mail, the recipient e-mail addresses whose transmission conditions are not satisfied are stored.

The sender mail address stores the mail address of the sender of the held mail. The sender's e-mail address indicates to the sender that the e-mail has been discarded, for example, in the event that transmission was not possible even after retransmission processing was performed for a predetermined period or a predetermined number of times (transmission conditions were not satisfied). It is used when notifying in such as. The mail data is a mail file name or the like for specifying the held mail. The transmission date and time stores the date and time when the proxy server 100 first received the mail, or the transmission date and time from the sender included in the retained mail. For example, the transmission date and time are used for discarding the mail when the transmission is not successful even if retransmission processing is attempted for a predetermined period. For example, if the predetermined period is set to 100 hours, mails that have passed 100 hours or more from the reception date and time will be discarded. The number of times of retransmission processing stores the number of times the held mail is retransmitted. For example, the proxy server 10
A value of 0 counts the number of times of retransmission processing corresponding to the retained mail when the retransmission processing of the retained e-mail is tried every predetermined time (for example, every hour) but the transmission condition is not satisfied. Then, the number of retransmission processing times is equal to or more than the number set as the allowable number of retransmissions (for example, 99 times or more).
, The held mail is discarded. here,
When the sender's mail address included in the mail is directly used, storage of the sender's mail address may be omitted. When the transmission date and time included in the mail is directly used, the storage of the transmission date and time may be omitted.

Next, with reference to FIGS. 2, 3,
This will be described with reference to FIG. For example, transmission condition information 100a
Assume that the setting contents shown in FIG. The setting content is the recipient mail address “ccc@ccc.c
om ", the receiver ID, the receiver password, the reception of the transmission condition, the transmission time zone, the transmission day of the week, and the destination mail address are" 1111 "," cccc "," OK ",
"9:00 to 20:00", "-(unspecified)", "-
(No designation) ". Similarly, the setting contents of the user of the recipient e-mail address “ddd@dddd.com” are “2222”, “dddd”, “OK”, and “9: 00 to 2”, respectively.
0:00 "," Tue, Mizuki ", and"-(no designation) ". In addition, the recipient mail address “ee@eeee.c”
om ”is set to“ 3333 ”and“ ee ”respectively.
ee "," OK ","-(unspecified) ","-(unspecified) "," gggg@gggg.com ", and the settings of the user with the recipient mail address" ffff@ffff.com " Are "4444", "ffff", "pause",
"-(No designation)", "-(no designation)", and "-(no designation)". It is assumed that nothing is currently stored in the standby information 100c.

[Operation Example 1: Immediate Discard of Mail] From the above state, the sender A in FIG. 2 (for example, the sender's mail address “yyy@yyy.com”) is sent to the destination mail address “ffff @ ffff”. .Com ”will be described. The sender A is the terminal device 1
Using 0, a mail transmission request signal including the user identification information and the mail is transmitted to the mail server 200. When the mail server 200 receives the mail transmission request signal including the user identification information and the mail from the terminal device 10, the receiver mail address (in this case “ff”) included in the mail is received.
f ＠ ffff. com "), not the proxy server 100
Is set to send to.

The proxy server 100 is a mail server 200
Receives the mail from the recipient, the recipient mail address included in the mail (in this case, “ffff@ffff.co”
m ”) is confirmed as to whether or not a recipient mail address that matches the address is stored in the transmission condition information 100a. In this case, since there is a matching recipient e-mail address, the reception condition of the transmission condition is checked next. In this case, since the acceptance condition is set to “pause” (the destruction condition indicating discarding is set), the mail is discarded, and the mail is sent to the sender mail address “yyy@yyy.com”. ,
It notifies by mail that the mail addressed to the recipient mail address "ffff@ffff.com" has not been transmitted.

{[Operation Example 2: Transferring E-mail] Next, FIG.
Sender A (for example, sender email address “yyy”
{Yyy. com ") is the destination mail address" ee
e @ ee. com "will be described. The caller A uses the terminal device 10 to

Receives the mail from the recipient, the recipient mail address included in the mail (in this case, “ee @ ee.
m ”) is confirmed as to whether or not a recipient mail address that matches the address is stored in the transmission condition information 100a. In this case, since there is a matching recipient e-mail address, the reception condition of the transmission condition is checked next. In this case, since the reception condition is set to "permitted", the transmission time zone and the transmission day of the week are checked subsequently. In this case, since both the transmission time zone and the transmission day of the week are “− (no setting)”, it is determined that the transmission condition is satisfied. Next, the transfer destination e-mail address is confirmed. In this case, the forwarding mail address is "gg
g @ gggg. com ”, the mail is transmitted to“ gggg@gggg.com ”.

[Operation Example 3: Holding / Retransmitting Mail] Next, the sender B (for example, the sender's mail address “zzz@zzzz.com”) in FIG. The case where an e-mail is transmitted to “ddd.com” will be described. The sender B transmits a mail transmission request signal including the user identification information and the mail to the mail server 200 using the terminal device 11. When receiving the mail transmission request signal including the user identification information and the mail from the terminal device 11, the mail server 200 receives the receiver mail address included in the mail (in this case, “ddd @
ddd. com ”), and is always set to be transmitted to the proxy server 100.

The proxy server 100 is a mail server 200
Receives the mail from the recipient, the recipient mail address included in the mail (in this case, "dddd@dddd.co"

In this case, since there is a matching recipient e-mail address, the reception condition of the transmission condition is checked next. Further, in this case, three recipient mail addresses are separately confirmed.

First, the recipient e-mail address "ccc @ c
cc. com ”, the reception condition is set to“ permitted ”, so that the transmission time zone and the transmission day of the week are checked. In this case, the transmission time zone and the transmission day of the week are "9:00 to
20:00 "and"-(no setting) ".
For example, if the current time is 07:00:00 (07:00:00) on April 9, 2001 (Monday), the proxy server does not satisfy the conditions of the transmission time zone, and the mail is sent to the proxy server. Keep without sending. Then, the standby information 100
"cc" corresponding to the recipient
c @ ccc. com ", the sender's mail address stores" yyy@yyy.com "corresponding to the sender, the mail data stores" yy1 "corresponding to the file name of the mail, and the like. "2001 /
04/09, 07:00:00 ”is stored, and the number of retransmission processes is initialized (for example, set to“ 0 ”). In addition, the sending date and time, besides the date and time received by the proxy server,
The transmission date and time included in the mail may be stored.

Next, the recipient mail address “ddd @ d
dd. com ”, the reception condition is set to“ permitted ”, so that the transmission time zone and the transmission day of the week are checked. In this case, the transmission time zone and the transmission day of the week are "9:00 to
20:00 "and" Tue, Mizuki ". For example, if the current time is 07:00:00 (07:00:00) on April 9, 2001 (Monday), the proxy server does not satisfy the conditions of the transmission time zone, and the mail is sent to the proxy server. Keep without sending. Then, "ddd @ dd" corresponding to the recipient is added to the recipient mail address of the standby information 100c.
d. com ", the sender's mail address stores" yyy@yyy.com "corresponding to the sender, the mail data stores" yy1 "corresponding to the file name of the mail, and the like. "2001/04 /
09, 07:00:00 ”is stored, and the number of retransmission processes is initialized (for example, set to“ 0 ”). In addition, as the transmission date and time, the transmission date and time included in the mail may be stored in addition to the date and time when the proxy server receives.

Next, the recipient mail address "ee @ e
ee. com ”, the reception condition is set to“ permitted ”, so that the transmission time zone and the transmission day of the week are checked. In this case, the transmission time zone and the transmission day are both "-
(No setting) ", it is determined that the transmission condition is satisfied. Next, the transfer destination e-mail address is confirmed. In this case, the transfer destination mail address is “gggg @ gggg.
com ", the email is sent to" gggg
{Gggg. com ". As described above, when a plurality of recipient e-mail addresses are set, transmission conditions for some recipient e-mail addresses are not satisfied, and transmission conditions for other recipient e-mail addresses are satisfied and transmission is performed. At the time, information on the recipient mail address for which the transmission condition is not satisfied is stored in the standby information 100c.

Next, a description will be given of the process of retransmitting the retained mail. The proxy server 100, for example, every predetermined time (1
(E.g., every hour), the contents of the standby information 100c are confirmed. Then, it recognizes that “mail data yyy1” of “to ccc@ccc.com” and “mail data yyy1, zzz1” of “to ddd@dddd.com” are held, and the recipient of the transmission condition information 100a is recognized. Email address ccc @ ccc. com and the transmission condition corresponding to dd
d ＠ ddd. com, and confirms the transmission conditions corresponding to each of them. And the current date is 08 April 2001 (Monday) 08:
In the case of 00:00 (08:00:00), since neither of them satisfies the condition of the transmission time zone, the mail is held without being transmitted, and the number of retransmission processing is counted.
In this case, 9: 00: 0 on Monday, April 9, 2001
Since both transmission conditions are satisfied at the time of checking after 0, the corresponding mail (in this case, no transfer destination mail address is specified) addressed to “ccc@ccc.com” (in this case, yyy1) And send "ddd @ dd
d. com ”(in this case, no forwarding destination email address is specified) (in this case, yyy1 and z
zz1) is transmitted.

Next, an embodiment will be described in which the present mail server has a transmission condition judgment function without using a proxy server. ◆ [When the mail server that manages the recipient's mail address of the user is provided with a transmission condition judgment function] The embodiment shown in FIG. In this example, the mail server 400 is replaced with the mail servers 120 and 150 with a transmission condition judging function. The mail servers 120 and 150 with the transmission condition judging function provide the mail server 300 or 400 with the proxy server 1 described above.
00 transmission condition determination functions 122 and 152 (transmission condition determination and retransmission processing, etc.) are added. The storage devices of the mail servers 120 and 150 with the transmission condition determination function store transmission condition information in which transmission conditions corresponding to recipient mail addresses are set.

Mail server 120 with transmission condition judgment function,
When the mail 150 is received from the terminal device 30, the portable terminal device 40, or the like, to the recipient mail address not managed by itself, the 150 sends the received mail to the recipient mail address included in the mail. On the other hand, when the mail servers 120 and 150 with the transmission condition determining function receive mail addressed to the recipient mail address managed by themselves, the mail servers 120 and 150 correspond to the recipient mail address of the received mail stored in the transmission condition information. It is determined whether or not the transmission condition to be performed is satisfied. Then, when the transmission condition corresponding to the mail recipient address included in the received mail is satisfied, the received mail is transferred to the mail receiving areas 125 and 155 corresponding to the recipient mail address. To be stored. Mail receiving area 125,
The mail stored in 155 is transmitted when the recipient accesses, or is automatically transmitted when the portable terminal device of the recipient is in a communicable state. If the received mail does not satisfy the transmission conditions, the received mail is not stored in the mail reception areas 125 and 155, and the mail server 12 with the transmission condition judgment function is not stored.
0 and 150, and a retransmission process is performed at each predetermined timing. Here, the mail servers 120 and 150 with the transmission condition judging function hold mail addressed to the recipient mail address managed by themselves, and a plurality of recipient mail addresses included in the received mail are set. Alternatively, only the receiver's mail address managed by itself may be stored in the standby information. This is because, in this case, the mail has already been transmitted by the mail server 200 for each recipient mail address. In this example, the process related to sending and receiving mail to a recipient mail address that is not managed by itself is the same as that of a conventional mail server, but the process for receiving mail addressed to a recipient mail address that is managed by itself is not performed. The transmission condition judgment function is added.

{[When a mail server that does not manage the user's recipient mail address is provided with a transmission condition determination function]] The embodiment shown in FIG. This is an example in which the mail server 200 is replaced with a mail server 110 with a transmission condition determining function. The mail server 110 with the transmission condition judgment function is the mail server 2
The transmission condition determination function 112 (transmission condition determination and retransmission processing, etc.) of the proxy server 100 described above is added to the function 00. The storage device of the mail server 110 with the transmission condition determining function stores transmission condition information in which transmission conditions corresponding to the recipient mail address are set.

Mail server 110 with transmission condition judgment function
When a mail addressed to a recipient e-mail address not managed by itself is received from the terminal device 10, 11 or the like, the transmission condition corresponding to the recipient e-mail address of the received e-mail stored in the transmission condition information is satisfied. It is determined whether or not it has been performed. Then, when the transmission condition corresponding to the recipient mail address included in the received mail is satisfied, the received mail is transmitted to mail servers 300 and 400 corresponding to the recipient mail address. Also,
If the transmission condition is not satisfied, the received mail is held in the mail server 110 with the transmission condition judgment function,
The retransmission processing is performed at every predetermined timing. here,
The mail server 110 with the transmission condition judging function holds the mail, and when a plurality of recipient e-mail addresses included in the received mail are set, all the mails for which the transmission conditions are not satisfied are set in the standby information. Store the recipient's email address. This is because, in this case, the mail is transmitted from the mail server 110 with the transmission condition judging function to each recipient mail address.

When the mail server corresponding to the recipient mail address of the received mail is the mail server 110 with the transmission condition judgment function (for example, when the mail is transmitted from the sender A to the sender B in FIG. 6). When a mail addressed to the recipient mail address managed by the user is received), the received mail is stored in the mail receiving area corresponding to the recipient mail address of the mail server 110 with the transmission condition judgment function. I do. Further, when receiving the mail from the mail servers 300 and 400, the mail server 110 with the transmission condition determining function stores the received mail in a mail receiving area corresponding to the recipient mail address. The mail stored in the mail receiving area is transmitted when the receiver accesses the mail, or is automatically transmitted when the portable terminal device of the receiver is in a communicable state. In this example, the sending condition judgment function is added to the process related to sending and receiving mail to the recipient mail address not managed by the user. However, the process of receiving mail addressed to the recipient mail address managed by the user is performed. Is the same as a conventional mail server.

{When both the mail server that manages the user's recipient mail address and the mail server that does not manage the user's recipient mail address have transmission condition judgment functions] The embodiment shown in FIG. 7 is different from the mail transmitting / receiving apparatus of FIG.
This is an example in which 00, 300, and 400 are replaced with mail servers 110, 120, and 150 with a transmission condition determination function. Mail server 110, 120, 150 with transmission condition judgment function
In addition to the functions of the mail servers 200, 300, and 400, transmission condition determination functions 112, 122, and 152 (transmission condition determination and retransmission processing, etc.) of the proxy server 100 described above are added. . The storage devices of the mail servers 110, 120, and 150 with the transmission condition determination function store transmission condition information in which transmission conditions corresponding to recipient mail addresses are set.

Mail server 110 with transmission condition judgment function,
When receiving a mail addressed to a recipient mail address not controlled by the terminal device or the like, the transmission conditions corresponding to the recipient mail address of the received mail stored in the transmission condition information are satisfied. It is determined whether or not it has been performed. Then, when the transmission condition corresponding to the recipient mail address included in the received mail is satisfied, the received mail is transmitted to the mail server with the transmission condition judgment function corresponding to the recipient mail address. In addition, the mail server 110 with transmission condition judgment function, 1
20 and 150, upon receiving an e-mail addressed to the recipient e-mail address managed by themselves, whether or not the transmission condition corresponding to the e-mail recipient address of the received e-mail stored in the transmission condition information is satisfied Judge. Then, when the transmission condition corresponding to the recipient mail address included in the received mail is satisfied, the received mail is stored in a mail receiving area corresponding to the recipient mail address. The mail stored in the mail receiving area is transmitted when the receiver accesses the mail, or is automatically transmitted when the portable terminal device of the receiver is in a communicable state.

In this case, for example, if the sender A
When the mail A is transmitted from 0 to the recipient C, the mail server 110 with the transmission condition determination function first checks the transmission conditions. Further, the mail server 120 with the transmission condition judgment function
However, the transmission condition is confirmed, and the transmission condition is confirmed at two places, so that one is useless. Therefore, the mail condition determination function may be set to operate in the mail server with the transmission condition judgment function only when the mail addressed to the recipient mail address managed by itself is received. The operation in that case is the same as in FIG. Further, the mail condition determination function may be set to operate on the mail server with the transmission condition judgment function only when the mail addressed to the recipient mail address not managed by itself is received. The operation in that case is the same as in FIG.

FIG. 8 shows an example in which the sender and the recipient are the same mail servers 120 and 150 with the transmission condition judging function (an example in which the transmission and reception of the mail are completed by one mail server). In FIG. 8, the mail servers 120 and 150 with the transmission condition determining function are the proxy server 10 described above.
0 has transmission condition determination functions 122 and 152 (transmission condition determination and retransmission processing, etc.). The storage devices of the mail servers 120 and 150 with the transmission condition judgment function include:
Transmission condition information in which transmission conditions corresponding to the recipient mail address are set is stored. The mail servers 120 and 150 with the transmission condition determination function are
1. When an e-mail is received from the mobile terminal device 20, 40 or the like (in this example, an e-mail addressed to a recipient e-mail address managed by the user) is received, the received e-mail stored in the transmission condition information is received. It is determined whether the transmission condition corresponding to the sender's email address is satisfied. And
When the transmission condition corresponding to the mail recipient address included in the received mail is satisfied, the received mail is stored in the mail reception area corresponding to the recipient mail address. The mail stored in the mail receiving area is transmitted when the receiver accesses the mail, or is automatically transmitted when the portable terminal device of the receiver is in a communicable state. Further, it is also possible to set the transmission condition judgment function to operate when the mail server 120 with transmission condition judgment function receives an e-mail addressed to a recipient e-mail address not managed by itself.

{[Registration / Change of Transmission Condition Information] Next, a method of registration / change of transmission condition information will be described. Registration /
There are three types of change methods. Since the recipient e-mail address is open to the public to a third party or the like, it is necessary to avoid unauthorized registration / change by the third party or the like. The first is a method of registering / changing using a recipient mail address actually used by the user. First,
The user accesses the proxy server or the mail server with transmission condition judgment function, and the registration / change request information including the recipient mail address (transmission condition registration mail request information)
Send Then, the proxy server or the mail server with the transmission condition judgment function transmits the registration / change information (transmission condition registration mail) to the recipient mail address. Upon receiving the registration / change information (transmission condition registration mail), the user transmits the registration / change information (transmission condition registration mail including the setting) including the desired transmission condition setting to the proxy server or the transmission condition judgment function. Send it to the attached mail server (reply in this case). Upon receiving the registration / change information including the setting of the transmission condition, the proxy server or the mail server with the transmission condition determination function receives the recipient mail address based on the transmission condition included in the received registration / change information, Transmission condition information such as transmission conditions is stored. According to this method, at the time of registration / change, the user must use the transmission condition registration e-mail sent to the recipient e-mail address to be actually registered / changed. Tampering can be avoided.

The second is a method in which registration / change is temporarily set, and then temporary registration / change is determined using a recipient mail address actually used by the user. First, a user accesses a proxy server or a mail server with a transmission condition judgment function, transmits registration / change request information including a recipient mail address, and temporarily registers (or temporarily changes) transmission conditions and the like as it is. I do. Then, the proxy server or the mail server with the transmission condition judgment function
Confirmation information including the contents of the temporary registration (or temporary change) is transmitted to the recipient's e-mail address of the user. The user receives the confirmation information including the contents of the provisional registration (or provisional change) and, if there is no problem, transmits the confirmation information including “confirmed information” to the proxy server or the mail server with the transmission condition judgment function (in this case, ,Reply. When the proxy server or the mail server with the transmission condition judgment function receives the confirmation information including the “confirmed information”, the provisional registration / change setting is validated based on the “confirmed information” included in the received confirmation information. (Also stored in the transmission condition information). According to this method, at the time of registration / change, the user must use the confirmation information including the content of the temporary registration (or temporary change) delivered to the recipient e-mail address to be actually registered / changed. It is possible to avoid unauthorized registration / change by a third party.

A third method is to periodically notify the user's recipient e-mail address of the current setting contents after setting registration / change. First, a user accesses a proxy server or a mail server with a transmission condition determining function, transmits registration / change request information including a recipient mail address, and directly registers (or changes) transmission conditions and the like.
Is carried out. Then, for example, the proxy server or the mail server with the transmission condition judging function is periodically (every week, etc.).
Then, the current setting contents of the transmission condition information are notified to the recipient's e-mail address of the user. According to this method, it is relatively difficult to avoid unauthorized registration / change by a third party or the like, but registration / change processing is easy. In addition, it is possible to confirm unauthorized registration / change by a third party or the like with the settings that are periodically notified.

Next, the first method will be specifically described with reference to FIG. As shown in the example of FIG. 9, first, the user uses a terminal device (in this case, the portable terminal device 40) to access a proxy server or a mail server with a transmission condition determination function. An example of a screen displayed on the terminal device when accessing is a transmission condition registration mail request screen 10
0d. ID as a user (transmission condition information 1)
00a) and a password (corresponding to the recipient password of the transmission condition information 100a), the transmission condition registration mail request screen 100d
When the user inputs "ID" and "PassWord" and selects "execute", the transmission condition registration mail 100f can be received from the proxy server or the mail server with the transmission condition judgment function.

ID (recipient ID of transmission condition information 100a)
) And a password (corresponding to the recipient password of the transmission condition information 100a), select "acquire new ID".
0e is displayed, and the mail address (transmission condition information 100
a), an ID (corresponding to the recipient ID of the transmission condition information 100a), and a password (corresponding to the recipient password of the transmission condition information 100a). This new ID acquisition screen 100
If "acquire" is selected after inputting e, the screen returns to the transmission condition registration e-mail request screen 100d.
When D and PassWord are input and "Execute" is selected, the transmission condition registration mail 100f can be received from the proxy server or the mail server with the transmission condition judgment function to the recipient mail address. Here, new ID acquisition screen 1
If "acquire" is selected after inputting "00e", the transmission condition registration mail 100f can be received from the proxy server or the mail server with the transmission condition judgment function to the recipient mail address.

The user sets transmission conditions and the like using the transmission condition registration mail 100f delivered to the recipient mail address. In “1. E-mail address” of the transmission condition registration e-mail 100f, the e-mail address already input on the new ID acquisition screen 100e is set. The user is (2) transmission conditions, (1) reception conditions, (2) transmission time zone, (3)
Set the sending day and “3. Forwarding mail address”, and send the sending condition registration mail including the sending condition setting.
The data is transmitted to the proxy server or the mail server with the transmission condition judgment function (in this case, a reply). The proxy server or the mail server with the transmission condition determination function stores the contents of the transmission condition registration mail, such as the transmission condition and the transfer destination mail address, in the transmission condition information 100a. Then, based on the transmission condition information 100a, transmission condition determination processing and retransmission processing of the proxy server or the mail server with the transmission condition determination function are performed.
