Comment More comprehensive (Score 3) 259
I actually tested this more comprehensively by sending all the email I got at my domain to one inbox, and using nameofdomain@mydomain.com to figure out where the spam was coming from. I was surprised that I didn't get any from my Slashdot account despit people's paranoia about it here. The biggest culprit was a single newsgroup posting that I made, netting me over 140 spam messages.
