This looks to be a subject with much discussion, mainly in 2006. Is there or will be there be any update and action on this or is comcast still an issue? Is the issue just with forwarding or will it apply to discussion lists also.
I'm just taking over a website for a non profit, and they were in the middle of trying to move from a different hosting company, which had no problem with comcast - but did have aol and yahoo issues..... This sounds like just trading one issue for another.
