I find all this hard to believe and wouldn't except that Alexander and Paul have said it and I am not one to fault their conclusions so it would seem that having email on anywhere but verizon seems to be an imperative. That said - I have my connections from cox - and I don't use my cox.net mail address - they apparently have issues too...but the cable internet is pretty fast and cheap bandwidth. Craig
