Cashing in my Nigerian Investments to Stock Up on Viagra and Date Sexy Russian Women

Not to mention certain "enhancements" I am offered on a regular basis. I have been puzzling over how to stop the avalanche of spam (ew, bad visual) I receive at home and work. At home, I am under assault from unwanted emails that come from an ever changing cast, so it is useless to blacklist them. I found the following free spam killers:

Spamato
Mailwasher
xTerminator
POPfile

I have been using Mailwasher--the main value of this free version seems to be the ability to check your mail before it is downloaded to your computer, useful for viral mail, but a waste of time in my situation. The University does a good job of filtering spam, I think, but displaying all of our email addresses on the web directory is an open invitation to unwanted solicitations. I know I need to check my home internet provider and see if they can offer any assistance. Any other suggestions?
