My Spamassassin kills off my spam. I occasionally get one that makes it past, but I just mark it, and I never see that kind again.
Of course, I rarely put my email address out on the net.
For some of us, that just really doesn't work. I've had the same email address for more than 10 years now, and it is apparently autogenerated within milliseconds of someone generating email addresses.
However, my email provider (pobox.com) does a damn good job of filtering mail.
I'd like to initiate the death penalty for both spammers and the morons who buy from them.
