Sounds like the issue might be with the service provider itself. I came across this question on a different forum: https://answers.yahoo.com/question/index?qid=20131217172003AA3ICwH

The question was perhaps very old, but it seems to be happening on different email clients.

It seems to be working. I think because I added @verizon.net to my Thunderbird username rather than just the name part of name@verizon.net. Thanks.
