I would set both sender_verify and headers_sender_verify. This will
prevent messages with incorrect email addresses from being accepted in
the first place.
I would also inform customers that in order for their mail to be
delivered correctly to an address, the email addresses (recipient
and/or sender) must be correct, and that email addressed incorrectly
will NOT be delivered.
