Hi all, I configured courier esmtpd for blocking spam, using a MAPS subscription. So far so good.

I also configured a secondary MX for each domain I host, using such service by an ISP connected via a different carrier. This also proved quite useful.

However, the two things don't match. Some spammers blocked by the main MX try the secondary one, which uses no MAPS lookup, and succeed. What should I do?

i) try an convince the other ISP to use MAPS ii) use a global courier filter to scan "Received"

iii) Get rid of the second MX.

A second MX doesn't get you anything unless your primary has been down for at least 24 hours, and if that happens you'll have other things to worry about.
