Could some kind person point me at the documentation (hopefully only one
document) which describes all the possible mail headers, who sets them, who

You may find RFC2076 "Common Internet Message Headers" to be of some
use. See: http://www.ietf.org/rfcs/rfc2076.txt.gz
Vernon Schyver's "You might be an anti-spam kook" web page has a list
of other important RFCs. See
