MailScanner increasing score over threshold but message passed as clean?

[Edward Prendergast]

I've hiked up the score below:

Treat Invalid Watermarks With No Sender as Spam = 3

But when this pushes the spam score over 5 with the addition of SpamAssassin
hits (my spam threshold is 5, high scoring spam is 10) the message gets
passed as clean. It appears that the score is getting added but ignored.

These are the hits from SpamAssassin:
cached	not	 
	score=2.197	 
5	required	 
2.00	ANY_BOUNCE_MESSAGE	Message is some kind of bounce message
-2.60	BAYES_00	Bayesian spam probability is 0 to 1%
0.10	BOUNCE_MESSAGE	MTA bounce message
2.70	FH_FROMEML_NOTLD	E-mail address doesn't have TLD (.com, etc.

This is the total score (as reported in MailWatch):
SpamAssassin Score:	5.20

Am I doing something wrong here or is this a bug?
