I might be completely off the bat here, but wouldn’t something like
formail (part of procmail) solve the probem of duplicates instead of
trying to hack a system of perl.

If you need to take account of messageid and listid it might not
help. Although you could run it on a per list basis with a different
cache (i.e. list of message ids) for each list.
