I think you missed the fact that sending files via SMTP is incredibly
inefficient. Any files sent via SMTP have to be encoded which can balloon
the transmission up 30%+. That is an incredible waste of bandwidth on a
10MB file. Also, remember that SMTP usually relays, so the message is
bounced between 1-8 servers along the way (or more), more bandwidth and
resources wasted. *sigh*
