The complete error message would be a clue. Since you cut it off there is no guessing what the issue is.

I didn't want to post my email address info. What info do you require? Thanks.

I was on my tablet when I first view this and the end of the error message was cut off.

The bolded message I quoted above is your solution. This has nothing to do with Thunderbird and no one here can help you. You need to have your ISP or email provider clean up their reputation so you can send mail again.
