Deja vu.

Haven't we covered this ground before?

The SMTP specification states that "HELO" is just a diagnostic command,
and it is meant only for troubleshooting, as in detecting mail loops where
a host talks to itself.

The SMTP spec, however, is a moving target (ok, at a tortoise's pace),
and at
some point it could evolve to have a more rigid semantic that could be the
basis for refusing connections.

When that happens, having the hooks already in place will be useful.
