immediately starts the verify, fails DURING the verify, and appears to involve
no other service I've defined.
All that's involved here is postscreen, its handoff smtp, and the address
verification step against the backend. How am I supposed to get this simpler
without removing postscreen or the address verification step or the backend?

It's good to keep saying 'simplify' and telling me to straighten out the helo
names.
How do I make this any simpler, and still have it at all relevant? And what
helo name, and where, needs to be corrected?
