The first rule in my .procmailrc does this with formail:

:0 Wh: msgid.lock
| /usr/local/bin/formail -D 8192 .msgid.cache

Doesn't move duplicates to the trash, it just prevents multiple copies
of the same message-id from being delivered at all.  The 8192 specfies
how large of a cache (stored in ~/.msgid.cache) of message-ids to keep
track of.
