Comment 108 for bug 2004480

Also, if you are **on Linux** and think you are still experiencing this specific bug(Origin: null in the header), make sure you are using 102.7.1 as it was released on https://www.thunderbird.net.

Multiple package maintainers built an untested, unreleased build of 102.7.1. If a 102.7.1 build originated prior to Jan 31, 2023, then it is probably a bad build and you need to update again.
