What kind of signature are you after? Who should be able to verify it?

To actually modify the message body and add MIME parts you'd probably
find it easiest to accept the outgoing mail with 'queue_only' into a
separate queue, and have a dæmon of your own which mangles it and then
moves it onto the 'real' Exim dæmon's queue for sending.

But would it suffice just to have a signature added in a header? Could
you just do this in a DATA ACL?

warn message = "X-Message-HMAC: ${hmac{md5}{YOURSECRET}{$message_body}}"
