It is, but if someone has faked the sender address, bouncing an e-mail
will most likely cause the sending MTA to send a failure notice to the
(faked) sender address, so you have to be careful.

I will probably remove the warning, though; it's a bit strong.  One thing:
I do not recommend action_notify_sender, because if someone has faked a
sender address, your notifications will go to the wrong person and/or will
bounce back to you.
