"Troubleshoot Windows Mail", and read the "I'm having problems sending
e-mail" section. If you need help determining the proper server settings,
please contact your e-mail service provider.

It is not surprising that you can't send through the Comcast server
since your connection no longer goes through them.
What error message do you get when sending through Verizon?
Right-click on that error message, copy, then paste it into a reply here.
We can't do much troubleshooting without the complete error message.
