Again, it is not clear that this is a Fetchmail problem - the problem was
created by an upstream ISP assigning the same message-ID to messages
destined for two different envelope addresses. But since my opportunity to
change the upstream ISP's behavior is nil, my only possible fix was in
Fetchmail.
OK, I understand now.
In 6.2.5 the dup killer will key on an MD5 hash of the raw headers.
So only true duplicates will be suppressed.
