I use both AOL and Comcast and I never have problems between the two. Joan In a message dated 10/4/2008 3:44:46 P.M.

There are times when AOL does not receive mail from either Comcast or Hotmail. I accuse my cherubs of ignoring me when I write and they insist they did and in fact forward me a copy of what got returned to them. Occasionally, I cannot get a mail thru to my daughter on Comcast; it gets returned as not a valid address. Ruth **************New MapQuest Local shows what's happening at your destination.
