I know this is off topic but bloggers receive spam too.
I want to tell you about an anti-spam product I'm now using and having tremendous success with.
I receive about 300 spam emails per day. I'm on a Mac. The Mac email client's built-in spam filtering is pretty good but far too many spam emails were getting through.
A few days ago I installed SpamSieve and the number of spam emails I have to deal with now in a day is maybe a dozen. And since SpamSieve 'learns', I expect that number will continue to drop.
