RE: [Declude.JunkMail] Mail Pre-Processor recommendations (ES)
I just installed Alligate in front of my decluded mail server and it certainly cuts down alot of the traffic to the mail server. Previously the cpu on the declude mail server was 60-90% all day, now it rarely goes over 10%. No more backscatter! No more dictionary attacks. Its pretty straightforward to configure and only took me about an hour or so. A small tip though in order to save all the pain of dns changes if you have many domains, to redirect all your smtp traffic to the Alligate server, you can configure your router to send all port 25 traffic to the Alligate server instead of the mail server. Declude is an excellent product, but add Alligate to it and you you are onto a winner.

The only reason that I can think of that your Barracuda box is seeing that many messages would be because you might not be validating addresses. Like Andrew said, you can cut your connection traffic by 95% with ease, but a large number of those connections are to bad addresses (backscatter and 'dictionary' attacks). You must validate addresses at your gateway. You can run Alligate on a single core box with 1 GB of memory and a single hard drive. Just make sure to dedicate the box to Alligate in order to avoid issues when resources are that sparse.

Nick Hayer said: I have a small utility that will allow Declude (for Imail) to run on an Alligate box without Imail being present. ... and it works. I'm using Nick's utility so that my antispam gateway is Alligate + Nick's utility instead of IMail. Like many people, I bought into Declude as my antispam product, and IMail just happened to be the platform it ran on. I'm much happier paying for Alligate than IMail. Ipswitch never made me happy. Never.
