Well, that's Anubis :-) But you have to think very carefully about *how* you change messages. If there's a 40Mb attachment, do you crypt and sign that? If the outgoing message is plaintext, do you convert it to MIME so you can include a signature, or do you sign the plaintext? And, which scheme do you use for signing? Is it dependant on the recipient, the sender, or the content?

 It should even decrypt and verify incoming e-mails. In one
word: It should act as an e-mail gateway!

It's not traditional to use Anubis for incoming email; perhaps you could use it in between the external MTA and the internal one; but I expect this would be a different invocation/daemon to the outgoing one. It's easy to have multiple daemons and difficult to set only one up for everything.
