in reply to Most of the email spam I get is:
I'm running 4 levels of filter.. a fetchmail preconnect deletes mail from certain countries (using the IP of the first received part) at the server (sorry, if you're from Korea or China, send me email to another of my addresses). Also all mail that is for other usernames on my domain, that dont actually exists as users or aliases on the system (one of these days, I'll figure out who "Castaway|castaway" is.. ). After that, its 3 levels of SpamAssassin, at 10, 5 and 2. I could probably merge the first two, I dont think Ive ever seen legit mail there since I started. Level 2 is fairly new, and catches both, so I check it often (still 95% spam though)..
Ah the joys of email.. I've had this address 10 years, and I'm not about to stop just for some stoopid spammers..
