Or wait for the heavy MTA that is trying to send you mail to notice
"hmm, looks like they're using greet_delay", and they send you an email
saying "can you give us an exception?"

I would personally prefer to have such a postmaster _ask_ me for an
exception, instead of trying to guess which heavy mail volumes I get
are legit and which are not.
