That should be.

I saw someone else (Richard Pieri) postulate that login names with a dot
in them were all throwing this error.  Does your login name have a dot?

Changing your IP address wouldn't make that difference unless the
Verizon smtp server was using one of those blacklists for *outgoing*
mail.  Off the top of my head that seems like it might not be a good
choice, and wouldn't think that is the main culprit.
