Re: EMAIL != FTP

Part of this discussion is just plain bizarre.

It is worth remembering that SMTP is, in most respects, simply FTP reworked.
In many ways, HTTP is FTP badly reinvented.

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

The one major difference, these days, is that EMAIL is often relayed over
multiple SMTP hops while FTP and HTTP are not.  So there are some queueing
issues.
