I've seen them (or similar headers) in messages that passed through one
or another third-party spam filter services (eg Postini, Messagelabs).
If you can correlate the values with some indication of spamminess you
might be able to get a slight boost in your SA effectiveness due to the
different rules/processes those large organizations use.
I've seen them in a few spams. I assume they're metadata generated by a
bulk mailing program.
That may be true as well. Keep watch and see what values or ranges of
values appear in what kind of spam - whatever the source, unless it's
just semirandom spamware garbage designed to give filter administrators
a headache it's programmatically related to the content in *some* manner.
