I am sorry to revive this old topic but I read this in the KB
SmarterMail includes a Windows version of SpamAssassin out of the box. By default, SmarterMail will run a version of SpamAssassin on 127.0.0.1 port 783. The System Administrator can enable and disable SpamAssassin through the Anti-Spam Administration link in the Security menu.
So.. SpamAssassin should work?
