Need Help with My Email Settings

[pnshields]

Please Help.... 1. I have listed the SMTP mail host info given to me by my ISP. I get "Unable to connect to mail server smtp.east.cox.net" error. Then I tried using the SMTP.gmail.com because I use Gmail rather than COX (who is my ISP). I get the same error message. I need to know where I find the authentication info as well.

2. I get "invalid email" when I try the test for the destination email. What have I done wrong there? I appreciate any help. I'm fried.
