Some Spam still not being marked as Spam

[Michael Keightley]

I'm using MailScanner-4.13-3 with SpamAssassin-2.50 (no AWL) on Solaris 9.
About 5% of Spam we receive isn't marked as Spam.  If I save these messages
and run "spamassassin -t" on these messages they get a much higer score
(e.g. 9 instead of 4).  Why is the score lower when they are processed by
MailScanner?  Is this a bug?
