Interesting, but how can those mails become delivered with a
"status=undeliverable"? Except, that you don't use reject_unverified_recipient
in your smtpd_recipient_restrictions, true?
Jan and myself need explicit "warn_if_reject reject_unverified_recipient" in
postfix' smtpd_recipient_restrictions ...

... to get such mails delivered.
