Many years ago (mid-90's), I made the mistake of using my work email address when posting to some programming forums. I now receive thousands of junk mail a week and unfortunately my employer won't change my email address. I'm finding that Mail is not particularly good at identifying junk mail as I get the same crap over and over every day. Each day I mark it as Junk... and each day it shows up in my Inbox again. For example, every morning there is an email for Gevalia coffee from "Gevalia <smtp@quitzaq.com>". Why can't Mail figure out that it's junk? I mark it as Junk every day!!! That's just one of many examples. I still get hundreds of similar junk emails showing up in my Inbox daily. I'm meticulous about marking them as Junk... but it doesn't seem to help.
Advice anyone?
