Since one of the lase TB versions HTML mails are sent as plain text, but only if no formatting is applied. This is a problem because for plain text mails I configured line wrap. So lines are wrapped unexpectedly. A suitable workaround is to add a bold space character, but sometimes I forget.

This is the header of such a mail:

User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 

Thunderbird/52.5.0

Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable Content-Language: de-DE MIME-Version: 1.0

Thanks a lot!

Unselecting "send message as plain text if possible" solves my problem.

I suppose is a new option with a non backward compatible default setting (selected). I never noticed it before and did not observe messages being sent as plain text when composing as HTML.
