My University of Alberta email account is the only account I have that I dont get at least 10 spam mails a day from. My Shaw (ISP) account, which I activated when I signed up, then NEVER USED (EVER, I dont even know what the address IS without looking it up) and I logged in in December to over 2000 spam messages. And that was in less than 4 months!!!
I have yet to find a good spam blocking program that doesnt block non-spam emails as well, but I usually use gmail which does a really good job of filtering spam (still though, they insist that ChemBio News is Spam about every other newsletter)
