(replying where I have something semi-intelligent to add.) > Thunderbird is the least worst option (in our opinions :). I use TB when I use macOS. TB does weird thing to plain-text email formatting, though. E.g. it sometimes refuses to let me delete lines that contain "> ", and it sometimes freaks out when I try to insert al line break in a section of quoted text. (I reply inline, like a civilized emailer.) > I tried Evolution for a week, about a month ago, and have used KMail and Thunderbird a lot. I’ve used all three for years. KMail would be my preferred option if it was way more stable and less buggy. It has great features and I feel at home in it. But it works way less reliably than Evolution. The version of KMail shipping on Flathub doesn’t even start. —and that’s when it’s running in a sandboxed environment that’s identical on everyone’s systems! > There's also a 'send later' add-on available. I know. https://www.ctrl.blog/entry/kmail-cve-2017-9604-openpgp.html https://www.ctrl.blog/entry/kmail-cve-2017-9604-openpgp.html On a related note, I couldn’t login to my IMAP account with KMail maybe ten years ago. My password back then contained an apostrophe. KMail didn’t encode it properly and would crash every time it tried to submit the password to the server. The bug also made it impossible to overwrite the saved password with a new one from the UI. > Actually, after seeing your article's screenshot of Evolution with KDE titlebars. The screenshot is manipulated, see disclaimer at the bottom of the article. It’s indeed running under Plasma, though.
