I normally *detest* when people respond saying I don't know about your 
setup, but my setup X works great!

So please feel free to tell me to bugger off. :)

That said, I've gone through a couple mail systems in my time, and the 
spam component was getting just terrible. I mean, ready to abandon 
entire domains. Spamassasin, Amavis etc just didn't work for me. Then I 
started with postgrey, and oh wow... virtually no spam at all.

Postgrey requires postfix, but I'd be surprised if there wasn't an 
equivalent for other MTAs. All it does is, when it sees a new address, 
it sends back a temporary failure message to the sending MTA telling it 
to try again in five minutes. Given that the vast majority of spammers 
ignore all returned messages, the spam never gets sent again. Meanwhile, 
real MTAs happily acknowledge the error, wait and send the message again 
successfully.

It's hard to overstate my satisfaction.

Huge success.
