I just can’t find a decent email client that looks like it’s from the last 20 years. Geary and Evolution both appear to be pretty modern but something about using Gmail with a Yubikey just doesn’t work and neither of them will connect to my account. Both on Fedora and OpenSUSE. Thunderbird works but it’s so old fashioned and Betterbird doesn’t look much better. What’s everyone else using?
I see. Well Thunderbird is not the only mail client, there are other good alternatives. Hope you find something that works for you. Who knows what the actual problem is, sometimes one can’t figure it out and has to use an alternative.
