undeliverable bounces to nonexistant spammer addresses, and
you will eventually get blacklisted as a backscatter source.
If you want to use luser_relay, make a single hash list of ALL
your valid users, regardless of where they are delivered, and
point local_recipient_maps at that list.
On today's internet a design that accepts mail to any address
and then generates a bounce for the undeliverables is just
irresponsible. A design that accepts mail to any address and
then discards undeliverables (or sends them to a catch-all,
which isn't much different) is a little better; at least that
way you only screw yourself and not innocent bystanders.
The way to fix your design is to create a list of all your
I suppose you could use reject_unverified_recipient if you're

goes then back all the way to the original user as a bounce. I will change
my configuration too.
