(Anti) Spam headers of various scanners

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
 
I'm looking for a list of Anti-Spam headers and their output. On a
rare occasion, I find that a previous MX has marked a message as spam,
but my own SpamAssassin installation hasn't. So I'm thinking of
putting in some header checks in maildrop which mark mail as [Probable
SPAM] if my own SA-score is above a certain level and if a previous MX
has marked a message as SPAM.

But in order to do that, I need a list of used AntiSpam headers and
their output and Google wasn't able to provide me with a recent and
up-to-date one.

I found the following in Bayes.pm (but they miss the output format,
logically)

  # Spamfilter/virus-scanner headers: too easy to chain from
  # these
  |X-MailScanner(?:-SpamCheck)?
  |X-Spam(?:-(?:Status|Level|Flag|Report|Hits|Score|Checker-Version))?
  |X-Antispam |X-RBL-Warning |X-Mailscanner
  |X-MDaemon-Deliver-To |X-Virus-Scanned
  |X-Mass-Check-Id
  |X-Pyzor |X-DCC-\S{2,25}-Metrics
  |X-Filtered-B[Yy] |X-Scanned-By |X-Scanner
  |X-AP-Spam-(?:Score|Status) |X-RIPE-Spam-Status
  |X-SpamCop-[^:]+
  |X-SMTPD |(?:X-)?Spam-Apparently-To
  |SPAM |X-Perlmx-Spam
  |X-Bogosity

BTW: I'm missing  X-Qmail-Scanner  in the above list (SpamAssassin 3.1.7)

Does anyone know of a good online resource of AntiSpam headers +
examples or has anyone got a recent up-to-date list themselves?

Kind Regards,
Sander Holthaus
