Exim Mail Relay
A quick question I am hoping some can help me with.
How can I prevent a single IP address from send mail through our server, but
allow the rest of the class C?
I have already tried:
host_accept_relay = "1.2.3.0/24:!1.2.3.9/32"
(address changed to hide open MTA)
The situation is one of our satellite customers are running an open mail
relay (sigh), and are using our server as a smarthost for delivery. Until
their technician can get onsite to fix the mail server (sigh), I want to
stop this spam at our e-mail server by blocking all outgoing e-mail from
them.
