I was going to answer Eli privately about this, but maybe it's going
to be useful to others too, so here is a small suggestion. You know
that emails all have a message ID that is unique to the email. The same
email sent to a mailing list and an individual will have the same
message ID. So you can use that to filter out doubles. Here is a
procmail recipe that does just that:

# The following 2 rules will avoid e-mail duplicates (these duplicates
# are stored in the duplicates folder instead).
:0Wch:.messageid.lock
| formail -D 32768 .messageid.cache

:0a:
duplicates
