What about comparing Message-ID headers of incoming messages to
existing messages, similar to the way nnmail-split-fancy-with-parent
works?  I don't mind duplicate messages so much if they end up in the
same folder, but I don't want to have to set up mailing lists for
everything.  Especially since I don't necessarily group messages by
mailing list.  For instance, my "ding" folder contains messages
forwarded from the newsgroup, mailing list messages, and personal
discussions about bugs.  So for me, the "mailing list == folder"
assumption doesn't work too well.

Maybe there could be an explicit comparison of messages with identical
message IDs.  If the message body is a duplicate (plus or minus some
user-defined variable fodder that some mailing lists inject) then the
user could choose to delete that message.

Thanks
