So it doesn't happen that often. I did try writing an SA header rule for
these first, but it appears that SA strips out 'X-Spam-Flag' headers out
before the rules are run.
SA Strips out X-Spam-* on the assumption that it previously added them.
Previous to 3.0 it did this before the rules ran on the text. Now I think
you can still get to them with full rules, but I think they are still
stripped from normal header rules.
If you have something like procmail in the chain before SA you can change
incoming X-Spam-* to something like X-PreviousSpam-* and end up with them
present to scan.
