Actually, it's roadrunner.. if you look at the designated address, most of them are going to different roadrunner addresses than yours. I have tampabay.rr.com at the end of mine and in the last week, I have gotten tons of misplaced email, some to me, some to other tampabay.rr.com users..
it's frustrating and ticks me off even more when I call them up and complain, only to get "yeah, that sometimes happens"
ARE YOU KIDDING ME? fix it, dumbass!!!
So if that sounds like what you are getting, rest assured, it's your local roadrunner being a lazy bird.
BTW, my husband is a computer security expert and we have every possible copy of anti-spyware programs out there(it helps to use multiple programs since one doesn't catch them all) we have corporate Symantic antivirus, and we have one hell of a firewall including ipcop... and we STILL get this crap.
