>From the procmailex man page:
If you are subscribed to several mailinglists and people
cross-post to some of them, you usually receive several
duplicate mails (one from every list). The following sim-
ple recipe eliminates duplicate mails. It tells formail
to keep an 8KB cache file in which it will store the Mes-
sage-IDs of the most recent mails you received. Since
Message-IDs are guaranteed to be unique for every new
mail, they are ideally suited to weed out duplicate mails.
Simply put the following recipe at the top of your rcfile,
and no duplicate mail will get past it.
:0 Wh: msgid.lock
| formail -D 8192 msgid.cache
Works for me. :)
