Hi, i'd like to have exim bounce mail to a particular address, so i added this to my virtual aliases:-
bugs-2007: :fail: Mailbox expired, please edit the address and try again
my understanding is that this should reject at smtp level with code 550 and including that message, but instead it rejects with "550 unknown user"
is my understanding of :fail: corrrect? in that the message should be used in the smtp response?
