On Friday I decided to change the subscription address to a lot (read around 70) of my mailing lists and realised that sadly for me Thunderbird doesn’t rock. As on date it does not allow the migration of filters/Message Rules across accounts that are configured in Thunderbird. The option in my case has been to hand create the filters for all those lists again. A major pain. There’s a bugreport though thankfully. Additionally, it might be a good idea for mail clients to have a MoveFolderTo option available on right-clicking a selected folder. The current way to do that in Thunderbird is a drag-n-drop which merely copies the desired folder to the target location. That’s bad too.
