The other option is to forget about creating rules and lists and instead get an effective anti-spam utility. And when I say effective I do mean C-Command Software’s $30 SpamSieve. We don’t dish out five-mouse ratings lightly, but in this case it’s completely deserved. I’ve relied on SpamSieve for years as have many of my colleagues. It really is the best way to deal with this crud.
Admittedly, I’m biased, as Michael Tsai, the man behind C-Command, is a personal friend. I was on the original beta test team for SpamSieve, and have used every iteration since 1.0 hit the ether. If you’re a Mac user, this is the first app you should buy.
