Sorry for newbie question

X-Virus-Scanned: Debian amavisd-new at mailgw.cost.it
X-Spam-Score: -
X-Spam-Level: 
X-Spam-Status: No, score=x tagged_above=-200 required=3

You get an 'x' if score is not known - bacause SA was not
called.
Reason of not calling SA could be mail size above
$sa_mail_body_size_limit,
or recipient required bypassing of spam checks.
