Every Verizon user that we have assisted with this issue has ended up ultimately resolving the problem by following the steps outlined below.
SOLUTION – Here is how our hosting customers who use Verizon for their internet access have fixed their outgoing SMTP email problem:
1. In your email client software configuration settings, set your outgoing SMTP server to outgoing.verizon.net , port 25
2. Set the outgoing SMTP server to use Authentication (not SPA, but rather, SMTP Authentication)
3. Set the SMTP authentication to use the username and password that was assigned to you by Verizon upon your DSL or FIOS installation. If you do not know the username and password you will need to call Verizon support and obtain it from them. They will reset your password if you forgot it.
4. Once you have saved those settings, the first time you try to send email from your own domain email account your email software will ask you for verification of the Verizon password. Enter it and PUT A CHECK in the REMEMBER MY PASSWORD box.
From that point on you should be fine, but if not then rest assured that you can contact us for help and we will assist you! We will not leave you out in the cold to figure it out for yourself, we will help you fix your problem to the best of our ability, and so far we have helped resolve the issue for every customer who has come to us with it.
