Thunderbird error RFC 5321: Apparently this problem was solved 9 years ago, but I faced it for the first time today.
Today (27th August 2025), I got the RFC 5321 error with every email I was sending to. On checking with Thunderbird help, I came to understand that this issue was solved 9 years ago. I have been using Thunderbird for about 2 years now. I faced this error for the first time today. Is there something new that has happened?
