The usual cause of this is that A is subscribed.  Mail to A is forwarded
to B, which no longer exists.  B's site bounces to listserv who not
having B as a subscriber, can't autodelete A.

Another possibility is that A's site bounces the mail with a different
address.  I.e. A = [log in to unmask] and the bounce is from [log in to unmask]
