I've just had some bounces from addresses @fsfe.org with errors like "550 5.1.1 something@fsfe.org: Recipient address rejected: User unknown in local recipient table"
Do people lose their addresses @fsfe.org if they don't pay again?
If those users are non-renewers, can you please add a more meaningful error than "User unknown in local recipient table" (maybe either "gone away - please contact something@some.other.domain" or at least "user no longer known") so that poor postmasters like me can figure out the cause?
Thanks,

While I don't think I've ever seen a mail server distinguishing between emails that email addresses that have been deleted and email addresses that simply did never exist, I agree that it could be helpful.
Can anybody help me with a pointer to how we would achieve that in postfix?
Thanks, Reinhard

In exim4, it is possible to do :fail: Custom error message as the alias return value - I've used it quite often on some systems, particularly for frequently-made typos.

Postfix seems to be very limited in this respect. By aliasing them to "|exit 77" you might be able to return "permission denied" rather than simply "user unknown" but I'm not sure whether that's enough to actually hard-bounce a message.
If anyone knows how to do it with postfix, I'd like to know too!
Thanks,

It seems Postfix can do the same, or at least something similar: http://readlist.com/lists/postfix.org/postfix-users/7/38978.html
