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?
