I am using a Dell Pc, with Xp home edition, not a Mac. I use Cox hi speed internet as a server.
My incoming email is pop.east.cox. net. This works
My outgoing server is smtp.east.cox. net
Somehow the out-server is called smTP, not tp, and I can't get rid of it, altho smtp.east.cox.net is there and is apparently not functioning.
Cox says they don't support Mozilla for troubleshooting, so I approached Mozilla.
If you are unable to resolve this, I will cancel my current account and start over which will irritate me more than I cam say.
