there are two cases:
- you enforce authentication and sender-login match. in this case, you
detect forgeries
- you don't. in this case, you can't detect forgeries. and a header
won't help. the whole approach breaks.

and how do you add a header only to "really" sent mail? and anyway, how
do you deliver a _copy_? remember that this is outgoing mail and won't
naturally go through dovecot.
