Attachments uploaded to web based mail are sent using HTTP. Attachments
downloaded from web mail are retrieved using HTTP. Attachments sent via
mail are sent using SMTP, and attachments retrieved using mail are via
POP/IMAP. You have to run a content filter on each protocol to see what's
being passed around. The only FTP is used is when a link on a web page
goes to an ftp:// URL, otherwise HTTP is used.
