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?
Switched from the default win10 mail app to thunderbird about a year ago when the mail app started forcibly updating to the outlook and broke some shit on my windows installation to use a whole lot of resources. I quite liked the old mail app of the windows, but Thunderbird is quite enough of a replacement at default settings and much more customizable after fiddling. K9 has no difference than Gmail on default settings, either.
