I'm not sure. Replying to a message with multipart/alternative and
hidden parts and attachments leads to quite a mess, to be honest (which,
I presume, is the reason for the current default).

I'll set it to no part headers, but I might find an option to insert
part headers for parts with "content-disposition: attachment"
interesting. Either that, or the current default plus no headers for
single part messages.

BR,
Jani.
