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/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.
