MailScanner.conf seems to be okay.  However, in spam.assassin.prefs.conf
I seem to have had my bayes_ignore_header lines misconfigured, so they
didn't match the X-MailScanner-* headers in MailScanner.conf.

Could this be tainting my spam training (significantly)?  If so, do I
need to clear out the old data from my bayes database and start over?

Also, should I add certain client headers to this list (e.g., evolution,
mozilla, or whatever)?

At first glance no, but I'll need to monitor from here out to see.
