The mobile phone 11 (for example, a product of Company A) refers to a pictographic table (for example, unique to Company A) and quotes it when inserting an emoticon into a sentence (text body) when creating and editing an e-mail. An argument (a-1) corresponding to a pictograph (for example, a telephone mark) is added to the header of the electronic mail as pictograph additional information. Here, when a plurality of pictograms are used, arguments corresponding to the pictograms are listed and added. The e-mail header includes a destination (recipient) mail address and a sender (sender) mail address. The e-mail in which the pictographic additional information (argument) is added to the header in this way is transmitted from the mobile phone 11 to the mail server 51.
[0027]
Next, the function for the e-mail with pictographs in the mail server 51 will be described with reference to FIG. FIG. 6 is an explanatory diagram showing an example of an e-mail process in the mail server 51. The mail server 51 analyzes the header of the received electronic mail, and is information included in the header, based on the domain name after the @ mark of the destination (recipient) and sender (sender) mail addresses. The carrier type (communication carrier) is determined. Further, the mail server 51 determines whether there is pictogram additional information in the e-mail, that is, whether the e-mail contains a pictogram by whether there is an argument in the header.
[0028]
When the mail server 51 determines that the sender / receiver is not the same carrier and the e-mail contains pictographs, the mail server 51 transmits the e-mail to the pictograph conversion server 6. On the other hand, when the sender and receiver are the same carrier, or when the pictograph is not included in the e-mail, the e-mail is transmitted to the mail server 52 on the receiver side.
[0031]
