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
