BleepingComputer.com: Outlook not sending out emails

I am trying to help a client with a outlook email issue. He has two computers in the house and two email accounts. A desktop and a laptop that both connect to the same network just one LAN and one wireless connection. he has a verizon email account and an outboundlcc.com email account. The verizon email address can send and receive on both computers. His nboundlcc.com email cannot send from the desktop or laptop and gets a smtp error when trying to send out. This does not happen on the laptop when he uses a USB verizon wireless adapter. He thinks the problem started when he switched his router to a netgear Dual Band router. Could the router have something in the settings preventing his email from sending. Why would it not happen with his verizon email and does happen with his nboundlcc email. He also has Norton on the computers, which might be blocking the emails from going out. I am just speculating and am unsure what this error could be caused from. I checked both computer outlook settings for the nboundllc.com email and they are identical. Any ideas?

Please post the entire error message he receives when he tries to send mail.

The error message is key to trying to resolve the situation.

Thanks for the reply. I think this post below is very similar to my problem. I will get you the error message. If the below post is correct then what port should I set the outgoing mail to? Why is the verizon account working and not the nboundllc account?

Problem solved. I changed the outgoing server (SMTP) to 587 and this fixed the problem. I guess it just wasn't able to connect when the port was 25. Thanks for the help.

Thank you for letting us know the issue has been resolved.
