Server, server system, and e-mail delivery method

摘要

An object is to provide a server and an e-mail delivery method capable of processing an e-mail while determining whether the e-mail is to be stored into a mail box or whether only an attached file is to be stored into a storage area specified by a URL, based on a file size of the attached file. Data determining part 102 determines a file size of a file attached to an e-mail received by SMTP communication part 101. When the data determining part 102 determines that the file size is not less than a predetermined file size, data processing part 103 provides the e-mail with identification information for making the file stored in storage part 204 specified by a URL, and the e-mail is transferred to external WEB server 200. When the data determining part 102 determines that the file size is smaller than the predetermined file size, the e-mail is stored in mail box 105.
