Thank you for the response!

A wild guess at an appropriate config option would be "Use Custom Spam Scanner".  My question is this: which comes first, SpamAssassin, or Custom Spam Scanner, in the actual process?

Also, does the reported "score" from Custom Spam Scanner get applied to the SpamAssassin Score (i.e. for calculating spam actions)?  If not, how is the reported Custom score used by MailScanner in determining an action?
