Spamassassin not detecting spam

[George]

Hi,

I am new to MailScanner so please excuse me if this is a stupid help request.

I have CentOS 5 with the latest MailScanner, the latest ClamAV, the
latest SpamAssassin, the latest Postfix and the latest MailWatch.

I set everything up using the docs from www.mailscanner.info

I set up the SARE spamassassin rules.

The issue is that all messages that are scanned by MS/SA get a 0 spam score.

The SA lint show that all the rules/filters are parsed but in the end
the spam score is almost always 0

Am I doing anything wrong? Where should I look at? Is this the right
place to ask for help?

Thanks
