I may be wrong myself, but this seams to be a bit of a myth going around
this thread. Adding a footer shouldn't break a GPG signature as GPG is
quite good at indicating what part of the message is signed. The eMail
is sent as a multipart/signed message consisting of:
 - multipart/signed
   - text/plain
   - application/pgp-signature

All the list processor needs to do is add another layer of
 - multipart/related
   - multipart/signed
     - text/plain
	 - application/pgp-signature
   - text/plain
and the Signature will remain valid. Some MUAs may choose to warn that
only part of the message is signed, but this shouldn't be a problem for
most people.
