Abstract

The present invention provides a mail extracting method of handheld device. First, a multimedia agent is used to access an e-mail from the mail host. The e-mail is then compared with mail extracting rules in a mail extracting rule database via a filter to extract a mail with appropriate format. Next, the mail with appropriate format is stored into a memory. Finally, the mail with appropriate format is transmitted to the handheld device. The mail extracting method finds out the content type of the e-mail via the key-tag thereof, accesses the mail type defined in the content type, and then checks the mail type to determine whether it conforms to the mail extracting rules in the mail extracting rule database. If the answer is positive, the e-mail is extracted to be a mail with appropriate format.
