Why are message attachments not measured in SPECmail2001?
A7: While ISP POP consumers do receive message attachments (i.e. MIME, Multipurpose Internet Mail Extensions), these attachments are a client-side issue under the POP3 and SMTP protocols. Since the email client is responsible for parsing MIME attachments within a message, there is no impact on the mail server except for message size. SPECmail2001’s message size distribution includes a consideration for attachments.
