Hello Jay,
The built in "SpamAssassin-Based Pattern Matching" is based off of SpamAssassin and specific patterns that we put in.
SmarterMail includes a proprietary pattern matching engine built upon the SpamAssassin technology as part of the default installation of the product. It includes a number of spam detection techniques, including DNS-based and fuzzy-checksum-based spam detection, Bayesian filtering and more.
This particular check is going to be reviewed.
Setting up your own SpamAssassin server will have the full capabilities and allow for customization on your part.
Hope this helped.
Thank you
Tony
