	Somewhat related, but from an 'end-user' viewpoint, I was finding
it annoying to receiving the same email in several 'filtered' mailboxes
because of cross posting.  Using procmail to do the filtering, if anyone
wants to get around this, try at the top of your .procmailrc:

----
DAYFOLDER=`date +%y%m%d`

# this will prevent 'crossposted' messages from getting duplicated
:0 Whc: msgid.lock
| formail -D 8192 msgid.cache

# this will backup the duplicates incase the above didn't work
:0 a:
$MAILDIR/duplicates/$DAYFOLDER

# save a copy of everything, just in case
:0 c
$MAILDIR/backup/$DAYFOLDER
----

	The backups are pure paranoia, and have never had to make use of
them...YMMV...

	Not related to Majordomo, but might help some out there to at least
control this on their end...
