I use Mailscanner with postfix and Mailwatch to manage quarantine etc;
On the backup MX, I just use postfix and some basic anti-spam stuff. Very little gets through and even less gets through to the primary. I am aware that some spam techniques go straight to the backup MX because most people don't set it up quite as well as the primary. YMMV.
I also used to use greylisting, which does reduce spam, but, unfortunately it also reduces valid mail ;-) In the end I'd rather suffer a few spams getting through compared to the delayed receipt of important emails.

Hello all,
About a year ago I set up a mail server on CentOS using this howto: http://wanderingbarque.com/howtos/mailserver/mailserver.html I managed to add amavisd-new with clamav and spamassassin. It runs very well, but it runs on CentOS 5.2, and if I try to upgrade, amavisd-new and clamav break. we are now also at the point where a backup mx will need to be implemented.
If necessary I am willing to implement a new mail server and a new backup mx.
What I would like to know is what solution you guys would recommend for the mail server and the backup MX?
Any pointers would be greatly appreciated.
