I would like a recipe that identifies duplicate messages and does
not trash them, but instead saves them to a different file. This
first attempt of mine does not seem to work:
# Deal with duplicates, as determined by Message-ID, but not if they
# have been looped through for multiple passes.
# :0 Wh: msgid.lock
* ! ^X-loop:.*qz.little-neck.ny.us
| formail -D 32768 msgid.cache
# Put dupes in a dupe file
:0e:
duped-mail
(I want a very large cache because I get maybe 3500 messages a week
passing through this rc file and I want to cache at least a full week.)
All messages get put in the dupe file with that. This is not helpful.
Also has anyone written a program that works just like 'formail -D'
for arbitrary fingerprints extracted from text? I think I could get
good spam reduction with a fingerprint composed of From: and
Subject: headers plus number of lines and bytes in the body. It would
also cut down on the time I have to deal with people who click 'send'
twice or the equivilent.
