I used SA-Exim before, now I switched to exiscan.
But Spamassassin isn't that good in any case, spammers are becoming more
clueful every day, and I think heuristic-scans like SA uses will work
worse with every day :-/. With some well forged headers one can trick SA
very easily.

I like to reject spam as soon as I can, and with my old static ip list,
I rejected 3-4 spammessages per day from .kr.

I know, it's not the best idea to block a whole country, but as I stated
before, I NEVER received a single legit mail from there :-/
