Help Outgoing mail not sending

[ThreeFingersDown]

At first I got my email to set up fine. I received a list of emails after i set it up, so I know it was connected. But then when I tried to SEND emails they wouldn't send.

I deleted my email account and started over, and now I can't even get it to set up correctly.

My incoming settings are
Pop mail.optonline.net
Port 110

everything works fine, on to the next screen

Outgoing
SMTP server
mail.optonline.net
port 25

Then I try to proceed and it just won't work.

If anyone could help it would be greatly appreciated!


EDIT:
The error I get is

"Warning - Cannot connect to the mail server to verify your account information. Your server is not responding"

Having the identical issue thru Time Warner. What is really annoying though is....if I turn off the WiFi, the mail will send fine. I turn it back on, won't send.
