From the Debian mailing list... Wondering, as this person is, if it is
possible..

Exim's filters are easy to read, but they don't seem to be as powerful
as procmail. I'd love to be wrong about that statement so I could switch
everything to exim. How do you remove messages with duplicate message
id's in exim?
from .procmail:
# remove duplicate messages, ie. to me and mailing list
:0 Wh: msgid.lock
| formail -D 32768 $MAILDIR/cache.msgid
You may not think dropping these messages is a good idea, but when a
mailing list gets hosed and spews several copies of every message I like
it.
