I use Mailscanner with postfix and Mailwatch to manage quarantine etc;<br><br><a href="http://mailscanner.info/">http://mailscanner.info/</a><br><br>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.<br>
<br>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.<br>

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