To follow up to this, *most* large email installations use different
machines/ips for mail receipt and for outward sending. If you insist
that connections have to come from the MX for the originating domain
then you will block out nearly all large ISPs. Whats more you will
block out people who have their own domain but send out mail via their
the ISPs smarthosts - ie that would apply to me at home.
