For testing, simply create a mailbox with a vanishingly small quota on some
destination system, then ... exceed the "warning level"...;-)

Yes, I verified it quite extensively.

The unverified_recipient_reject_code was confusing in this regard when I
read it at first. But upon closer examination in Postfix 2.6 there is an
unverified_recipient_defer_code which clued me into maybe that "reject" was
supposed to be modified. At first, I feared that it was going to
unconditionally reply 5xx to anything even for lesser offenses. But now that
I see the "defer" version, I'm quite convinced it's okay to change it to

After the change, I've tested it and it works. However, I am unable to
create a test situation where the final destination server would reply in
the 4xx or less. But I think it's working now. Thanks Glenn and everyone.
