I currently use Thunderbird. I’d like to use Boolean message filtering. An example follows:
If recipient address is firstname.lastname@example.org AND sender contains @canoe.com THEN send to WaterSports Folder
If recipient address is email@example.com AND sender contains @promotionalFitnessClub THEN send to Fitness folder
Thunderbird doesn’t allow this, as far as I can tell. Maybe it shouldn’t. Or maybe there’s a client that handles this well. Discuss.
I could set up an inbox for each recipient email address but… well I’m actually sending all my email aliases on to my gmail account to take advantage of their anti-spam filtering. So I’d like to do this with a filter option.
I could also try to find an appropriate plugin. I did that. No luck. The closest one is here, but it doesn’t work with recent versions of Thunderbird and isn’t under active development. It’s also marked as experimental.
Discussion of email filtering best practices is also welcome.
