When we first built our spam filters, over a year ago, it worked great out of the box. It was incredible. But, over time some spam started to get through. We were running SA 2.64. So I upgraded to SA 3.01. And about the same amount of spam was still getting through. Could someone please point me to some instructions on how to tighten down SA? Here is a copy of our local.cf. We are running OpenBSD 3.4, Perl 5.80, SA 3.01, Amavisd, DCC and Razor.
