spamasassin always score twice,

[Gao]

Hi, list,

I just setup a mail server with MailScanner and I found that spamasassin 
always score twice, one is "not cached" and the other is "cached". Is 
this a normal behavior?

here is a sample header:

X-mycompany-MailScanner-SpamCheck: not spam, SpamAssassin (not cached,
	score=-0.098, required 5, autolearn=not spam, DKIM_SIGNED 0.10,
	DKIM_VALID -0.10, DKIM_VALID_AU -0.10, FREEMAIL_FROM 0.00,
	HTML_MESSAGE 0.00, SPF_PASS -0.00, URIBL_BLOCKED 0.00), not spam (whitelisted),
	SpamAssassin (cached, score=-0.098, required 5, autolearn=not spam,
	DKIM_SIGNED 0.10, DKIM_VALID -0.10, DKIM_VALID_AU -0.10,
	FREEMAIL_FROM 0.00, HTML_MESSAGE 0.00, SPF_PASS -0.00,
	URIBL_BLOCKED 0.00)



Thanks for help.
