Exactly. You now need a protocol/layer that says you're running "mail 
over http" as opposed to "web". HTTP is tcp/80 that *means* web. As soon 
as you start using it for something (anything) else you've just added 
another protocol/layer.

I get the distinct impression that Grant doesn't actually understand 
what TCP is ... (hint - it has port numbers that are meant (if they're 
not abused) to indicate what is going over the connection, like SMTP, or 
HTTP, or POP, or IMAP, etc etc).
