Just recently, I am unable to send replies or attachments from my Thunderbird email. My service is Comcast and I have verified my outgoing server settings as directed by Comcast. I also tried turning off my Norton for outgoing mail, still having the issue. Last week emailed worked fine.

Have you checked with Comcast whether they have a problem?
