After generating the notification mail, in step S6, the mail receiving unit 1
03, the size limit identification flag 302, which has been set to ON, is turned OFF, and the reception size determination unit 1
The size of the arriving mail temporarily stored in 02 is cleared (step S8).

In step S7, if the size restriction notification flag 203 is OFF, the notification mail is not returned. Therefore, the restriction reception notification generation means 104 was set ON by the mail reception means 103 in step S6. The size restriction identification flag 302 is turned off (step S9).

After steps S5, S8, and S9, the mail server is searched for any other arriving mails (step S10).
The operation of / S9 is repeated, and if not, the mail transmission unit 105 transmits the notification mail temporarily stored in the limited reception notification generation unit 104 (step S11).

The contents of the notification mail are also sent to the restricted reception confirmation message display means 106, and the restricted reception confirmation message display means 106 confirms that the mail recipient has received the mail due to the reception size restriction. Is displayed on the portable information terminal device screen (step S12).

Thereafter, the mail server logout means 10
7, the connection with the mail server is terminated (step S13).

As described above, in the first embodiment of the present invention, the limited reception and the reception ratio are returned to the sender, so that the sender can know how much has been received, and If the e-mail is urgent or important, it will be possible to determine whether to send the previous e-mail within the limit size by dividing the previous e-mail or summarizing the contents by referring to the reception ratio. Have.

Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a block diagram showing the configuration of the second embodiment of the present invention.
9 is a flowchart showing the operation of the second exemplary embodiment of the present invention.

In the present embodiment, the subject of the restricted reception is replaced with the binary data attached to the mail from the size of the mail body. In general, binary attached mail has a larger overall size than ordinary text mail, and incompatible data files that cannot be handled by applications mounted on the mobile information terminal device, and applications that cannot be executed on the mobile information terminal device There is no point in receiving the message, and the mail storage area of the portable information terminal device is simply wasted.

FIG. 5 differs from the second embodiment shown in FIG. 2 in that a binary attachment judging means 108 is provided instead of the receiving size judging means 102 and stored in the mail transmission / reception setting section 200 and the mail storage section 300. This is the point that the size restriction related flag to be replaced is replaced with a binary restriction related flag.

Next, the operation of the second embodiment of the present invention will be described with reference to FIG.

First, when the user activates the mail application to receive an e-mail from the portable information terminal device 1A, the mail server login means 101 of the mail transmitting / receiving unit 100A connects to the access point 3 of the contracted provider. Then, the binary attachment determination unit 108 searches whether the binary attachment deletion flag 204 of the mail transmission / reception setting unit 200A is ON or OFF (Step S21).

If it is ON, the binary attachment judging means 108 removes the binary attachment part of the arrival mail. For example, in the case of a mail in MIME format, look at the "Content-Type" field in the mail header and check "mul
If it is "tipart / mixed", it is assumed that there is a binary attachment, and the "Content-Type" field that appears in the mail body is other than "text"("application","image","audio","vide
If "o"), it instructs the mail receiving means 103 to skip the contents of the receiving buffer up to the next "Content-Type" field line or the boundary end position, and save the others as a file.
Turns on the binary restriction identification flag 303 after being stored as the received mail 301, and requests the restriction reception notification generation means 104 to generate a notification. The mail storage unit 300A assigns a management ID to the received mail 301 in a form in which information of the binary restriction identification flag 303 is added, and manages the received mail 301 (Step S).
22).

If it is OFF, the binary attachment judging means 108 sets the mail receiving means 103 to receive the full text.
, And the mail receiving means 103
Is stored in the mail storage unit 300A (step S2).
3).

The restriction reception notification generating means 104 refers to the mail transmission / reception setting unit 200A and checks whether the binary restriction notification flag 205 is ON (step S2).
4).

If the result of the check in step S24 is ON, the restricted reception notice generating means 104 sets the binary restriction identification flag 303 of the received mail 301 managed by the mail storage unit 300A to ON. Search for a message and generate an e-mail with the contents restricted from receiving the binary attachment to the sender's e-mail address. Then, after generating the notification mail, the restriction reception notification generation unit 104 turns off the binary restriction identification flag 303 that was set ON by the mail reception unit 103 in step S22 (step S25).

In step S24, if the binary restriction notification flag 205 is OFF, the notification mail is not returned. Therefore, the restriction reception notification generation means 104 was set ON by the mail reception means 103 in step S22. The binary restriction identification flag 303 is turned off (step S26).

After steps S23, S25 and S26,
The mail server is searched for any other arriving mails (step S27), and if so, steps S21 to S21 are performed.
The operation of 23 / S25 / S26 is repeated.
The mail transmission unit 105 transmits the notification mail temporarily stored in the restricted reception notification generation unit 104 (step S28).

The contents of the notification mail are also sent to the restricted reception confirmation message display means 106, and the restricted reception confirmation message display means 106 confirms that the mail recipient has received the mail due to the binary reception restriction. Is displayed on the portable information terminal device screen (step S29).

Thereafter, the mail server logout means 10
7, the connection with the mail server is terminated (step S30).

As described above, in the second embodiment of the present invention, the fact that the binary restricted reception has been made is returned to the sender, so that the sender knows that the binary attachment part was not received. This has the effect that subsequent correspondence is possible.

Next, a third embodiment of the present invention will be described in detail with reference to the drawings.
