P.S. How come your user agent (Thunderbird) is not emitting
format=flowed messages? According to [1], it supports format=flowed, and
can only be disabled via editing option strings.

Although I can't promise that I didn't tamper with these settings, I
didn't find any non-default value in about:config in that area, but
there is a default setting "mailnews.send_plaintext_flowed = false".
This is now manually set to true, let's see.
