It is fairly easy to add a filter for the subject line, (The menu
location is a bit strange, Privacy Options / Spam Filters
I use something like

^subject:.*Arlington Digest, Vol

as that is the beginning of the subject line for the digest. the .* is
to allow for the re: (or whatever) to be added.

Catching the footer is harder, as mailman (as far as I know) only
filters on the header to the list, not the body. My list is plain text
only, so I set a size filter to catch messages which quote the whole
digest. It also catches people who attach things anyway, post in html
(sometimes) or don't trim excessive quotations (sometimes). I set the
filters to 'Hold' to allow releasing false positives or to write a
descriptive reject message.
