I think that you have an DSL Broadband Access from Verizon?
If yes, the Mail server settings are:
* Incoming mail server (POP3): incoming.verizon.net
* Outgoing mail server (SMTP): outgoing.verizon.net
* Your Verizon Online user name
* Your Verizon Online password
You have to check "outgoing server requires auth" and select "same as for incomin server"
I hope this will help you.
Feel free to ask again if anything is unclear.
