When I did some test connections to that IP address, the only time it
refused my HELO was when I didn't include a domain. It didn't seem to
matter whether I gave my correct domain or a bogus one. I did notice
that it was did reverse lookups and an ident query on me.
So, the things to check are:
o What do your control/me and control/helohost files look like?
If helohost exists, but is empty, that could make your qmail
issue a HELO without a domain. That might also happen if the
helohost file exists but isn't readable by qmail-remote.
o Does your machine have an ident daemon? I wonder if that
installation of Sendmail gets more picky about the HELO
greeting when the connecting host doesn't have reverse DNS
available and/or won't answer ident queries.
Hope this helps,
-Greg
