Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic mail transmitting apparatus for transmitting an electronic mail through a network, a program for causing a computer to function similarly to such an electronic mail transmitting apparatus, and a computer readable program storing such a program. It relates to a possible program medium.

[0002]

2. Description of the Related Art In recent years, electronic mail has exploded along with the Internet, so that much information can be exchanged without worrying about time. In recent years, portable information terminal (PDA) devices such as mobile phones and notebook-type small computers have become more sophisticated, and portable information terminal devices having functions of editing and transmitting and receiving e-mail have been developed. It has come to market. For this reason, coupled with the rapid increase in the number of subscribers such as mobile phones, networks capable of transmitting and receiving e-mails are expanding. Furthermore, despite being equipped with various functions such as an e-mail function, recent mobile phones and the like are becoming lighter and more convenient to carry.

[0003]

However, the number of characters that can be transmitted / received is limited in a portable information terminal device such as a portable telephone having an electronic mail editing / sending / receiving function due to a physical problem such as a storage capacity. There is something. Therefore, for example, when sending an e-mail from a normal computer to a mobile phone, the sender cannot confirm whether or not the number of characters that can be received at the destination is limited. I sometimes sent it. As described above, when an e-mail having the number of characters exceeding the upper limit is transmitted, the mobile phone does not receive the content exceeding the upper limit and does not display the content.

[0004] Further, when sending an e-mail with the same contents to a plurality of destinations at once, even if it is possible to determine whether the destination is a normal computer or a mobile phone, the destinations are selected. Since it is extremely troublesome to reduce and change the content of the e-mail for each transmission destination, the e-mail having the number of characters exceeding the upper limit must be transmitted at a time. For this reason, it has been difficult for a user of a portable information terminal device such as a mobile phone to obtain necessary information from the received e-mail.

Accordingly, an object of the present invention is to simultaneously send an electronic mail address for a portable information terminal device with a limited number of receivable characters and an electronic mail address for a normal computer with an unlimited number of receivable characters. When sending e-mail, an e-mail transmission device that can transmit only the necessary information to the e-mail address for the portable information terminal device, a computer that functions as equivalent to such an e-mail transmission device It is an object of the present invention to provide a program to be executed and a computer-readable program medium storing such a program.

[0006]

SUMMARY OF THE INVENTION The present invention, which is configured to achieve the above object, has a function of editing an e-mail composed of a message body and a mail header, and transmits the edited e-mail to another device via a network. In an e-mail transmitting device that transmits an e-mail, a list file in which a domain name included in an e-mail address where the number of characters that can be received is limited is described, and an e-mail address that is an e-mail destination to be transmitted, Address determining means for determining whether or not a domain name described in the list file is included; summary part identifying means for recognizing an identifier for dividing a message body of the e-mail into a summary part and a detail part; The e-mail address that is the destination of the mail is
If the number of characters that can be received is not the limited email address, the number of characters that can be received by the entire email message body and the email address that is the destination of the email to be sent is limited. If the e-mail address is an e-mail address, an e-mail creating means for creating an e-mail with only the outline in the message body of the e-mail, and the e-mail created by the e-mail creating means Transmitting means for transmitting.

With this configuration, when sending an electronic mail to another device on the network, if the device is limited in the number of characters that can be received, the electronic mail message body is Only the summary is sent as the content of the email. If the number of characters that the device can receive is not limited, the entire body of the e-mail message is transmitted as the contents of the e-mail.

Therefore, an operator who composes an e-mail in the e-mail transmission device does not need to recognize whether the number of characters that can be received by the transmission destination device is limited.
The message body of the e-mail is divided into a detailed part consisting of a description of the detailed contents and a summary part consisting of the summary, and is created. If an identifier that separates the summary part from the detailed part is entered, the number of characters that can be received is increased. Can be sent to a device that is restricted in terms of the outline.

[0009] Therefore, an operator who receives an e-mail in a device in which the number of characters that can be received is limited receives an e-mail having a content consisting only of the outline, and does not receive the e-mail with the content cut off without receiving the e-mail. Necessary information that must be received can be reliably received.

[0010] The list file of the e-mail transmitting apparatus according to the present invention includes, in addition to the domain name of the e-mail server apparatus (provider) constituting the network, the apparatus having a limited number of receivable characters as a main client apparatus. In addition, the upper limit of the number of characters that can be received by those devices may be described. By using this list file, the upper limit of the number of characters can be set according to the smallest upper limit of the number of characters in the e-mail address having the domain name included in the list file. If the number of characters in the message body (if there is no identifier) exceeds the upper limit, the user can be warned that the upper limit is exceeded.

Therefore, an operator who composes an e-mail in the e-mail transmission device does not need to recognize whether the number of characters that can be received by the destination device is limited or not. The minimum upper limit value can be easily known, and an outline can be easily created so as to fall within the upper limit of the number of characters.

[0012] The computer-readable recording medium according to the present invention stores a list file in which a domain name included in an e-mail address whose number of receivable characters is limited is described. This recording medium has a function of editing an e-mail composed of a message body and a mail header, and allows a computer that transmits an e-mail to another device via a network to a destination of the e-mail to be transmitted. Address determination means for determining whether a certain e-mail address includes a domain name described in the list file, outline part identification means for recognizing an identifier for dividing an e-mail message body into an outline part and a detail part,
If the e-mail address that is the destination of the e-mail to be sent is not an e-mail address with a limited number of characters that can be received, the entire e-mail message body and the destination of the e-mail to be sent If the e-mail address is an e-mail address with a limited number of receivable characters, an e-mail creating means for creating an e-mail with only the outline of the e-mail message body as its contents, and A program that functions as a transmission unit that transmits the electronic mail created by the electronic mail creation unit is stored.

In the electronic mail transmitting apparatus according to the present invention, by recognizing the identifier written in the message body, the part before and after the identifier may be divided into a summary part and a detail part. The outline part and the detail part may be created separately.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An electronic mail transmitting apparatus according to the present invention has an editing function for creating an electronic mail, a function for transmitting an electronic mail, and the like. When the transmission start instruction is given by the operator after being created separately, the e-mail address for the terminal device in which the number of characters that can be received is limited,
It is characterized in that only the outline part of the contents of the e-mail is transmitted, and the entire contents of the e-mail are transmitted to the e-mail address for the terminal device in which the number of characters is not limited. Hereinafter, an embodiment of an electronic mail transmitting device will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a network system to which an electronic mail transmitting device 10 according to an embodiment of the present invention is applied. FIG. 2 is a schematic configuration diagram of an internal circuit of the electronic mail transmitting device 10 of the present embodiment.

As shown in FIG. 1, an electronic mail transmitting apparatus 10 according to an embodiment of the present invention includes an electronic mail server 2
0 is connected to the Internet 40 via a network 30 such as a LAN or a general telephone line,
According to the SMTP protocol, various types of information can be exchanged with terminal devices such as the mobile phone 50 and the computer 60 connected to the Internet 40 via an e-mail server device (not shown) in the Internet 40.

The electronic mail transmitting apparatus 10 provided in such a network system can be configured using a generally available computer having an input device such as a keyboard, a display for displaying various screens, and a main body. The internal circuit of the main body is mainly composed of hardware such as a CPU 11, a memory 12, a hard disk drive (HDD) 13, a communication control board 14, and a CD-ROM drive 15, as shown in FIG.

The CPU 11 is a central processing unit for integrally controlling each hardware, and the memory 12 is a random access memory in which a work area of the CPU 11 is developed.

The HDD 13 stores an OS (Operating System) program for managing the execution of an application or performing system management such as network management. The HDD 13 also has an editing function for creating an e-mail and a network 30. An application program for executing a function of transmitting an e-mail to the e-mail server device 20 above is stored.

The HDD 13 is provided with a provider (mainly a portable information terminal device such as a portable telephone 50 or a pager (registered trademark)) whose main customers are limited in the number of characters that can be received when receiving an e-mail. Internet 4
A list file that describes the service provider that provides the IP connection service to the IP address 0 is stored. FIG. 4 shows an example of the list file. In the list file shown in FIG. 4, for each provider name (JDD momoko, N-TONE,...) Whose main customer is a portable information terminal device,
The domain name of the e-mail address in the e-mail server device of this provider (momoco.ne.jp, ni-p.ne.j
..) and the upper limit (200, 2) of the number of characters that can be received by the portable information terminal device registered with this provider.
..) Are separated by several spaces and arranged in one line, so that all data are described in association with each other.

The communication control board 14 shown in FIG. 2 is a network adapter, a modem, a DSU or the like connected to the network 30 via a network cable, and connects to the electronic mail server device 20 and the like connected via the network 30. It is responsible for passing data and parameters between them, or receiving results.

When various programs and data are upgraded, a CD-ROM disk (computer-readable medium) 16 storing a new program is set in the CD-ROM drive 15. Read programs and data. The program and data read out in this way are stored on the HD
It is installed in a storage device such as D13.

The CPU 11 that has read and executed the OS program in the HDD 13 can edit and transmit an e-mail by reading and executing the application program (mailer program) in the HDD 13.

When the mailer program is started by an operator's start instruction, an e-mail editing screen 1 as shown in FIG. 5 is displayed on the display screen (the above-described display) of the e-mail transmitting device 10. The electronic mail control process shown in FIG. 3 automatically starts.

As shown in FIG. 5, an e-mail editing screen 1 has a destination entry field 2, a send button 3, a subject entry field 4,
A warning column 5 and a content entry column 6 are provided. The operator enters the e-mail address of the desired destination in the destination entry column 2, enters the content of the e-mail to the destination (message body) in the content entry column 6, and enters the subject of the e-mail in the subject. You can fill in column 4. Further, when the operator wants to transmit e-mails having the same content to a plurality of transmission destinations at one time, the operator can enter a plurality of e-mail addresses in the destination entry column 2.

After the editing screen 1 is displayed, in the first step S01 in the e-mail control processing (FIG. 3), the CPU 11 changes the e-mail address entered in the destination entry field 2 to the content entry field 6 Set the upper limit of the number of characters of e-mail contents (message body) to be entered in.

That is, in this S01, the CPU 11 sets the e-mail address entered in the destination entry column 6 as shown in FIG.
Check whether any of the domain names described in the list file shown in (1) is included (corresponding to the address determination means), and if not, set the upper limit of the number of characters to “unlimited” and include If there is, set the upper limit of the number of characters. When setting the upper limit, the upper limit of the number of characters is set to the smallest value among a plurality of e-mail addresses entered in the content entry column 6 (corresponding to the number of characters setting means).

For example, in an electronic mail address having an upper limit of the number of characters, respective upper limit values are 100, 200, and 25.
If it is 0, the upper limit of the number of characters that can be entered in the content entry field 6 is set to the smallest “100”.

In the next process of S02, the CPU 11 checks the number of characters of the content (message body) of the e-mail entered in the content entry column 6 (corresponding to the outline section identifying means).
Then, it is determined whether or not the upper limit of the number of characters set in the process of S01 is exceeded. And the number of characters of the content is S0
If it is determined that the value is larger than the upper limit value set in the process 1, the process proceeds to S03.

In S03, the CPU 11 blinks the warning column 5 (corresponding to warning means), and returns the processing to S01. While the number of characters of the e-mail content (message body) entered in the content entry column 6 exceeds the upper limit, the CPU
Step 11 repeats the processing from S01 to S03.

At this time, the operator can recognize that the upper limit of the number of characters has been exceeded by blinking the warning column 5, and can take measures to prevent a warning from being issued based on the warning. As a method for coping with the warning, for example, an e-mail address having a low upper limit of the number of characters may be deleted, the number of characters in the content entry column 6 may be reduced, or as shown in FIG. Write the mark "/ PE" in the middle of the mail content (message body).

This mark "/ PE" divides the content (message body) of the e-mail entered in the content entry column 6 into a summary section 6a and a detail section 6b. When the mark "/ PE" is recognized in the contents of the mail, it is determined whether or not the number of characters up to the mark (that is, the number of characters in the outline section 6a) exceeds the upper limit.

On the other hand, in the process of S02, if it is determined that the number of characters of the content (message body) of the e-mail entered in the content entry column 6 does not exceed the upper limit, the CPU 11
Advances the process to S04.

In S04, the CPU 11 checks whether or not the transmission button 3 has been pressed by the operator. The operator enters an e-mail address in the address entry column 2,
The content (message body) of the e-mail is entered in the content entry field 6, a title based on the content (message body) is entered in the subject entry field 4, and then the send button 3 is pressed.

If the CPU 11 determines in step S04 that the send button 3 has not been pressed, the process proceeds to step S01.
And if it is determined that the send button 3 has been pressed, the process proceeds to S05.

In S05, the CPU 11 sets the destination entry field 2
Recognize all e-mail addresses entered in. When a plurality of e-mail addresses are entered in the destination entry column 2, each e-mail address is separated by a space, a line feed, a comma, or the like, and the CPU 11 recognizes each e-mail address in units of these delimiters.

In the next process of S06, the CPU 11
It is checked whether or not the e-mail address recognized in the process 05 includes the domain name described in the list file shown in FIG. 4 (corresponding to the address determination means), and all the e-mail addresses including the domain name are extracted. .

In the next step S07, the CPU 11 recognizes the content (message body) of the e-mail entered in the content description column 6. At this time, when the mark “/ PE” is entered in the content entry field 6, the CPU 11 recognizes only the content (message body) of the e-mail preceding this mark.

In the next process of S08, the CPU 11
Attach the e-mail address extracted in the process of step 06
The content of the e-mail recognized in the process of 07 (that is, the outline section 6a) is transmitted to its own e-mail server device 20 (corresponding to an e-mail creation means and a transmission means). At this time, the e-mail is obtained by combining an e-mail message body defined by the MIME protocol with an e-mail address, date and time, subject, and other information of the transmission side and the reception side defined by RFC822. Formed and sent.

In the next step S09, the CPU 11
S0 out of the e-mail addresses recognized in the process of 05
The e-mail address extracted in the processing of step 6 is deleted, and S1 is deleted.
It proceeds to the process of 0.

In S10, the CPU 11 sets the destination entry field 6
Of the e-mail (message body) entered in
Recognize. At this time, if the mark "/ PE" has been entered in the content entry field 6, the CPU 11 deletes this mark and recognizes the content of the e-mail.

In the next process of S11, the CPU 11
E-mail address (S06
And the contents of the e-mail recognized in the processing of S10 (that is, the outline section 6a and the detailed section 6b) are transmitted to the own e-mail server apparatus 20. (Corresponding to an e-mail creating means and a transmitting means). At this time, the e-mail is formed and transmitted in a format (a message body defined by the MIME protocol and a mail header defined by RFC822) exchanged on the Internet 40. Then, the CPU 11 ends the e-mail control process.

By the above operation, for example, “ef” is entered in the destination entry field 2 on the electronic mail editing screen as shown in FIG.
g@fujitsu.co.jp ”,“ hij@keitai.ne.jp ”,“ klm @ tes ”
h.ne.jp "and" nop@fujitsu.co.jp ", if you enter the four e-mail addresses," hij @ keitai.ne, jp "
And “klm@tesh.ne.jp” include the domain names “keitai.ne, jp” and “tesh.ne.jp” described in the list file in FIG. You have
The CPU 11 recognizes.

Thus, in the process of S01, the CPU 11 recognizes that the upper limit of the number of characters in these e-mail addresses is 200 characters and 1000 characters, and the upper limit in the content entry column 6 is the smallest upper limit value. "20
0 ”.

Further, in the process of S06, the CPU 11
The e-mail addresses of “hij @ keitai.ne, jp” and “klm@tesh.ne.jp” are extracted, and these two
One e-mail address is attached, and an e-mail composed of only the outline section 6a is transmitted.

Then, in the process of S09, the CPU 11 deletes the two email addresses extracted from the four email addresses, and in the process of S11,
The remaining e-mail address "efg@fujitsu.co.j
An e-mail including a summary part 6a and a detail part 6b is transmitted with "p" and "nop@fujitsu.co.jp".

The e-mail transmitted in the processing of S08 and S11 is once transmitted to the e-mail server 20 of its own provider via the network 30, and the e-mail server 20 transmits the e-mail indicated by the domain name of each e-mail address. To the destination e-mail server device,
It is transmitted through the Internet 40.

As a result, the terminal device that receives the e-mail transmitted in the process of S08 from the destination e-mail server device has a limited number of receivable characters. As shown in FIG. 7, the operator of the e-mail content (message body) entered in the content entry column 6 has the mark “/ P” as shown in FIG.
Only the outline section 6a separated by "E" can be received.

The terminal device that receives the e-mail transmitted in the process of S11 from the destination e-mail server device does not limit the number of characters that can be received. As shown in FIG. 8, the operator can receive all the contents of the e-mail (message body) entered in the contents entry column 6.

With the above-described configuration, the operator of the electronic mail transmitting apparatus 10 can know the upper limit of the number of characters of the transmission destination from the warning column 5, so that it is within the range of the outline section 6a. An outline of the contents of the e-mail (message body) can be created.

Therefore, the content (message body) is transmitted from the e-mail transmitting device 10 with the number of characters less than or equal to the upper limit of the number of characters of the mobile phone 50. ) Is not displayed due to lack of a part, and the minimum necessary information (that is, the outline) in the content of the e-mail (the message body) is accurately transmitted to the operator of the mobile phone 50.

Further, the operator can write the mark "/ PE" at any position (within the range not exceeding the upper limit) in the content (message body) of the electronic mail. The contents of the outline part can be finished in a place where the division is good, and the outline part 6a with incomplete contents is not created.

By the way, in the example of the electronic mail editing screen 1 shown in FIG. 5, after writing the contents of the electronic mail (message body) in one content entry column 6, a mark is placed at any place in the contents. The entry was divided into a summary section 6a and a detail section 6b. For example, the content entry section 6 is divided in advance as shown in an editing screen 1 'shown in FIG. A detail entry field 6'b may be provided. In this case, if the number of characters exceeds the upper limit in the summary entry field 6'a, the warning field 5 flashes and a warning is displayed.

At this time, in the destination where the number of characters is limited, an e-mail (ie, FIG. 7) including only the outline (message body) of the outline section 6′a is received, and the destination where the number of characters is not limited is received. Now, the overview section 6'a and the detail section 6 '
The e-mail combined with b (ie, FIG. 8) is received.
