Ok, giving:

accept domains = +local_domains
endpass
message = unknown user
verify = recipient

a try to see what happens.

In the meantime, I usually run with:

- Verify the existance of email senders
- Discard emails for users who have exceeded their quota instead of keeping them in the queue.

checked off. Any thoughts/results on what differences it makes, having them on or off?
