I had hoped I wouldn't need to do a deep dive on state-of-the-art
spam killing, but it's 2017 and the game has gotten tougher.

Thanks for these suggestions.  I'm implementing greylisting, pyzor,
razor, and the above client_recipient_restrictions.  dcc I don't
quite understand yet.

I think I'll phase this stuff in, with greylisting first, and see
what happens to the spam flow for each step.  I am a little wary
of putting even more chunks of perl and python into the critical
path.

Thanks a lot for the help, everyone.

  in 1995 using sendmail... and nothing else but exmh as the client)
