Doing a search brought back Geary and Claws Mail which are ones you are having issues with.
Claws Mail is recommended for Yahoo IMAP.
Now in the past some people had issues with Thunderbird not working because they installed the Flatpak version which did not work because mail ckients need to work with the system. Were any of the fails Flatpak versions?
I have BlueMail working, but I think it's using 500MB so I'll need a lighter client...
I've tried Claws but the log in process is too complicated & I can't complete it - plus I'm not sure you can 'unify' email accounts with it...
I've tried all versions of Thunderbird - the problem is it's using too much RAM which leads to my system maxing out(RAM AND swap)& then logging me out when it crashes...
