Apple Users

I also keep a "Suspected Spam" folder that I weed through and add addresses as needed. The most vital is the "Politics" folder -- any damned fundraising mail gets dumped in immediately, but they're crafty and keep coming up with new names!

I actually, though, have the opposite problem than the op...I get regular e-mails from, of all places, a body jewelry company i've certainly never order from nor ever had any correspondence with. But no matter how many times I mark it as JUNK, new ones just keep showing up. I do agree, training the filters can be a bit a bit tedious, but well worth it if you have a raining Saturday with nothing else to do.
