I'm working with Thunderbird's Send Options to figure out how to get my Thunderbird to send HTML to most people, but send plain text to the cranky folks who insist on text-only. It's 2020, and most people these days are fine with HTML email. I'd like the behavior to be that Tbird sends plain text when possible, and when I have formatting, it will silently go ahead and send HTML emails, except when one of the recipients in it is in one of the Plain Text domains or has been explicitly marked as preferring Plain Text in my address book.
I've enabled "Send messages as plain text if possible", and listed "@gnu.org" in my Plain Text Domains. I have not marked the preferred email type for any recipients in my Address Book.
If I change "When sending messages in HTML format...:" to "Ask me what to do", I'm now getting prompted about HTML formatting on every email I send. It seems that Tbird is seeing the "Prefers to receive messages formatted as: Unknown" in my contacts and treating that as "not known to receive HTML".
I would like to be able to set Thunderbird to assume that those Unknowns can receive HTML text, and only prompt me when there's a recipient who has been explicitly set to "Prefers: Plain Text" or is in the Plain Text Domains list.
