Known Issues

  • Auto Updater does not fully supported. (Update Checker is supported. But you should download and install new version manually.)
  • From 17.0, Tenfourbird doesn't contains Enigmail add-on. It provide separately. Enigmail for Tenfourbird 10.0.* or before does not automatically update. You should manually download and install Enigmail for Tenfourbird 17.0.* or later.
  • Sudden message deletion issue is reported. I think it may related Mbox compaction. I recommend mail backup before folder compaction.
  • There are also open tickets reported.
