[SA-exim] Bayes tweaks

[Paul Makepeace]

Actually RTFM I noticed the bayes_ignore_header option:

       bayes_ignore_header header_name
           If you receive mail filtered by upstream mail systems, like a spam-
           filtering ISP or mailing list, and that service adds new headers
           (as most of them do), these headers may provide inappropriate cues
           to the Bayesian classifier, allowing it to take a "short cut". To
           avoid this, list the headers using this setting.  Example:

                   bayes_ignore_header X-Upstream-Spamfilter
                   bayes_ignore_header X-Upstream-SomethingElse

Which prompted me to wonder about,

  bayes_ignore_header X-SA-Exim-Connect-IP
  bayes_ignore_header X-SA-Exim-Mail-From
  bayes_ignore_header X-SA-Exim-Rcpt-To
  bayes_ignore_header X-SA-Exim-Scanned
  bayes_ignore_header X-SA-Exim-Version

I can't decide whether this is worthwhile or not; there might actually
be bayes-classifiably useful info in there. Any thoughts?

HTH,
Paul
