feedmail-fiddle-headers-upwardly

feedmail-fiddle-headers-upwardly is a variable defined in `feedmail.el'.
Its value is
t


Documentation:
Non-nil means fiddled header fields should go at the top of the header.
nil means insert them at the bottom. This is mostly a novelty issue since
the standards define the ordering of header fields to be immaterial and it's
fairly likely that some MTA/MUA along the way will have its own idea of what the
order should be, regardless of what you specify.

You can customize this variable.
