We are acting as secondary MX for a few of our customers, one of who has
about 20 valid email addresses (including aliases).
I want to change the /etc/mail/access from a simple "RELAY" to something
that will check for valid addresses for that domain and reject any BS
ones. We are currently relaying everything and some spammers are firing
just_about_anything@xxxxxxxxxxxxx at our mail server which I relay to
the customers mail server which then bounces it back to me and I end up
with a load of mail in the queue that can never be delivered.
I read recently that this is possible using the "To:" access record but
so far I either pass everything or nothing.
Can anyone point me in the right direction please?
