But for a little extra SMTP handshaking at the start, there is no
difference in transfer rate between SMTP and FTP.  Probably the same is
true for HTTP though I've not looked.

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
After all, nmodep compress it back to the original size while transferring. The
rate loss is 5 - 10%, not 30 - 40.

For LAN, this volumes are not large (1 - 2 Mb).

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*
