Network Solutions prefers port 2525, "There are many ISPs that are now blocking the default outgoing port that many mail clients set up automatically. (Port 25) They do this to protect users from spam and viruses that direct infected machines to send through the default ports. Typically changing the port to either 2525 or 587 will resolve the issue." Form works fine now.
I am not getting an Error message like I should when I type the wrong answer into Security Code or Answer fields. Would you please check. Thank you.
