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'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.
