That might explain the some-what common sightings of SMTP connect and
immediate SMTP close entries in my server's log files.  I see maybe a
dozen of those on any given day.

The source might just be trojanized windoze PC's that are being used as
spam relays (zombies) that impliment a half-ass set of SMTP rules and
methods when they send their spam - one of which is the construction of
a malformed (non-compliant) HELO/EHLO greeting.

So it's probably a good thing that my server is adhering closely to RFC
821.
