And what's also stupid is that I have found that in my case, the entire IP range is blacklisted. I have done some digging around on this, and have found that the ISP is really 
responsible for maintaining their blacklist information. However, comcast is so stupid that they won't know what that is even if I explain it to them...So in my opinion why bother? What I end 
up having to do when I encounter blacklist problems is relay my mail through one of comcrap's smtp servers. Which is stupid considering I have my own domain and everything.
