Re: gnupg signing
This might be somewhat inconvenient, but how about including MD5 sums
of the attachments in the body of the message, which is then signed?
(i.e. md5sums *.jpg + cutnpaste)
But since you will do a lot of signing in the future, I'd suggest
using a mailer that handles gpg, as the others have suggested :)
