Ouch. "Free" e-mail sites.
But you're right. No such thing as a free lunch.
On the other hand, I get plenty of spam on Outlook. I think my service used to filter it better than they do now. Fortunately, I'm pretty good at designing my own filters, so little of it ends up in my inbox, but I still have to plow through the "junk" file before deletion to make sure no nuggets are in the dross.
