Electronic mail sending apparatus and method

An apparatus for sending an electronic mail via a network, the apparatus comprising:

• an image inputting device for inputting an image;
• a sending device operable to send an electronic mail to which said image is attached;
• a storing device for storing a relational information representing correlation between data size of respective electronic mails and transmittance results of said respective electronic mails for each mail-designation, wherein said relational information includes an unsendable threshold corresponding to a minimum data size among electronic mails whose transmission has failed;
• an updating device for updating said relational information in response to a mail-sending history of electronic mails;
• and
• a controlling device for controlling said sending device in response to said relational information.

A method for controlling the sending of electronic mail via a network, the method comprising the steps of:

• storing, in a storage device, a relational information representing correlation between data size of respective electronic mails and transmittance results of said respective electronic mails for each mail-designation, wherein said relational information includes an unsendable threshold corresponding to a minimum data size among electronic mails whose transmission has failed;
• updating said relational information in response to a mail-sending history of electronic mails;
• and
• controlling sending of a new electronic mail in response to said relational information.

A computer program stored in a computer readable storage media which, when read and executed by a computer included in an electronic mail terminal, causes the electronic mail terminal to perform the functions of:

• a sending device operable to send an electronic mail;
• a storing device for storing a relational information representing correlation between data size of respective electronic mails and transmittance results of said respective electronic mails for each mail-designation, wherein said relational information includes an unsendable threshold corresponding to a minimum data size among electronic mails whose transmission has failed;
• an updating device for updating said relational information in response to a mail-sending history of electronic mails;
• and
• a controlling device for controlling said sending device in response to said relational information.

A computer-readable recording medium recording a computer program which, when read and executed by a computer included in an electronic mail terminal to obtain an electronic mail terminal for sending an electronic mail, causes the electronic mail terminal to perform the functions of:

• a sending device operable to send an electronic mail;
• a storing device for storing a relational information representing correlation between data size of respective electronic mails and transmittance results of said respective electronic mails for each mail-designation, wherein said relational information includes an unsendable threshold corresponding to a minimum data size among electronic mails whose transmission has failed;
• an updating device for updating said relational information in response to a mail-sending history of electronic mails;
• and
• a controlling device for controlling said sending device in response to said relational information.

An apparatus for sending an electric mail, comprising:

• a mail sending module operable to send an electronic mail;
• and
• a controller operable to find a new electronic mail having data size larger than a threshold size,
• wherein said threshold size represents an unsendable threshold corresponding to a minimum data size among electronic mails whose transmission has failed and is updated in response to transmission results of electronic mails having been sent from said mail sending module.
