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.
