I wish I could fund a mail client for modern #GNOME. Geary is going to be stuck in GTK3 for the foreseeable future, Evolution, while nice, is in the same position due to it's custom widgets, and Thunderbird doesn't use GOA ...
It's a bummer that there is a whole IMAP/SMTP setting in GOA, but no GTK4 application consumes it!

@pojntfx Never heard of GOA... though I use #Gnome. Just searched for it... "Gnome Online Accounts" doesn't sound like something I want or miss. 🤷

Anyway, with mail clients I am "stuck" with #Thunderbird anyway, 'cause it's the only client I know that handles identities the way I want:
If I have my own domain like mydomain.com and so I do enter my email addresses at services like "random123@mydomain.com" I can easily send and reply with that sender without having to setup a whole account. Win.
