It looks to me like Thunderbird has a bug when you want to send plain text email that on sending and receipt flows itself to the width of the window.
To send flowed text that flows on the sending site, you set (in the config editor):
mailnews.wrap_long_lines=true (don't mess with my outgoing emails; just let them go as long as they need)
mailnews.wraplength=0 (don't have a specific line length; just wrap to the window length)
plain_text_wrap_long_lines=true (wrapping is great, particularly in the client)
mailnews.send_plaintext_flowed=true (regardless of what I send, the recipient should be able to rewrap it so it flows comfortably in their screen)
mailnews.display.disable_format_flowed_support=false (don't disable flowed text; I like flowed text).
On sending this works great; it flows to the border of the window and wraps, reflowing as you change text without needing to hit ctrl-r or anything (since all the wrapping is virtual).
However, when you send this way, your email will be sent as one long line, and on receipt, thunderbird will display it as one long line, not reflowing it at all.
On the other hand, if you tweak this by changing one line:
mailnews.wraplength=78 (or whatever, pick a length)
Then while composing it will stick stubbornly to 78 lines (or whatever). However, on reciept, because of format=flowed, it will reflow your message to your window size and look great.
Obviously this is a bug. By documentation, mailnews.wraplength=-1 should disable flowing at all; length=0 should send whatever it sends but reflow on client side, which it doesn't -- at least in thunderbird.
Is there a workaround (also, is this a live bug?)
This is from thunderbird 78.9.1 (32 bit).
