Re: [Declude.JunkMail] multistage filtering [OT]
And, besides, Postfix is FREE. I'm running 2.6 version, with Amavisd-new, SpamAssassin, Postgrey, together with BindDNS, and SQUID on a cheap machine -P4, 2 Gb RAM, 80 Gb HDD- under FreeBSD. In fact, 2 of them sharing loads. Just my 2 cents.

RE: [Declude.JunkMail] multistage filtering [OT]
I'm another Alligate fan on the Windows platform. It is a very smart and effective product. I have conservative settings that stick close to the defaults and my configuration rejects 80% of the inbound connections.Before I implemented Alligate, my Declude was hurting because of my large filter files. A combination of large filter files and large volumes meant heavy CPU and Disk utilization and conflict. I'm also a MessageSniffer fan, and know that you could be very happy with Pete's recommended solution. Implementing an MTA in front of your content scanner and mailserver is a resource that is well spent; the two layers have very different workloads, and I think you'll find that you need to upgrade the hardware on the content scanner less if you have an MTA that is filtering the connections first.

Re: [Declude.JunkMail] multistage filtering [OT]
It's definitely Alligate for this purpose. Instead of using something like Postfix or IMgate which will mostly replicate functionality found in Declude, Alligate will end up blocking things using unique functionality and it runs on Windows and uses very little CPU. The two main features of Alligate as a pre-scanning gateway are the selective greylisting functionality, where it will greylist senders only if they appear that they might be zombies (since greylisting is really only effective against zombie spam), and the other is the internal MXRate blacklist. I rarely block messages with permanent errors with Alligate, but by greylisting effectively, you can avoid having 95% of your E-mail traffic hit your second layer of scanning. It also does so selectively so that your legitimate E-mail will rarely hit it and cause any issues.
