So it looks like you're trying to send using a from: address which appears to have been removed, disabled or retired.

The message is from a server. You need to check if all the addresses offered in Thunderbird as from: addresses are current and valid.

But now I see other posts saying pretty much the same, which has me wondering if this is a problem at the server.

Who is your mail provider?
