Thomas, how did you manage to get CTE: QP on the received message? Which provider does that? MTAs shouldn't really mess with the message content, but painfully we know that some do, even in an very incompetent fashion messing up all highbit characters, see bug 1435903 and [https://wiki.mozilla.org/User:Jorgk/8-bit_bytes_and_e-mail_corruption_at_Verizon,_Yahoo,_etc.](https://wiki.mozilla.org/User:Jorgk/8-bit_bytes_and_e-mail_corruption_at_Verizon,_Yahoo,_etc.) Note that format=flowed and CTE: QP are (almost) virtually exclusive, see bug 1689804 comment #18, last paragraph.
