On removing reject_unverified_recipient, the rejection changes to
550 5.1.1 <bogus-recipi...@acrasis.net>: Recipient address
rejected: User uknown
which I prefer, not that it's vital to me. I confess I'm none too
clear now on the purpose of reject_unverified_recipient. Is there any
reason I should keep it?
