SpamAssassin domain rules

[Chris-Bellsouth]

I looked around in the archives and I am unable to find any references to
this...

I want to have different sa_user_prefs for each domain so that one domain
can have a dedicated SA configuration that is seperate from another domain
being scanned on the same MS system.  Is this possible?

Could I include a rules pointer here:

SpamAssassin Prefs File = %etc-dir%/spam.assassin.prefs.rules


That pointed to a rules file like this:

To        example.com        /etc/MailScanner/rules/example_sa_prefs.conf


where  /etc/MailScanner/rules/example_sa_prefs.conf was a SA prefs file
specific to example.com?
