No, the server itself need not have MX records and its hostname need
not match the envelope sender domain. The server must have matching PTR
and A records, and the envelope sender domain must be valid (have MX or
A records).
Processing bounces and spam complaints is NOT optional. There is no
such thing as "send-only" email, once one takes non-optional list
management into account.
