I find some SPAM slips through un marked, mostly from certain country codes (in the senders email address/domain).
I was thinking of a regex to taste and paste (say add 5 to SPAM score), but don't really want to reinvent a wheel. Or run over my own toes. I did find a plug in or two, but these seem to rely on checking the IP of sender or relay. Since my mail collects at a mail provider, I fetch(mail) it and pass it on to a box running spamassassin, they might not work un-hacked, in any case. Direction?
