Enable Pattern Matching
Built-in sophisticated statistical pattern matching algorithms can be used to match and block spam. This is a highly accurate mechanism for filtering junk email offering high rates of spam identification, typically around 95% and very low false positive rates (the number of email incorrectly blocked): typically less than 1 in 2,000 email.

Thresholds
Each email is given a score form 0% (almost certainly legitimate) to 100% (almost certainly SPAM). The triple slider allows you to set the three thresholds used to determine the outcome of the pattern matching:
Less than the first marker (in the white area) The email is not matched and will pass through unhindered
Greater than the first marker (in the light green area) The email will have its subject marked but be sent to the original intended recipient(s)
Greater than the second (in the blue area) The email will be blocked and optionally stored in the SPAM store
Greater than the third (in the red area) The email will be deleted and not stored
Below there are settings for subcategories of SPAM that can be used to disable the above actions (or force Marking instead) when an email matches a specific category. This can be useful if your business domain is similar to a SPAM category: for example if your company is involved with pharmaceuticals then the Pharmacological category may match legitimate emails, and it may be beneficial to disable that particular category.

Auto retrain pattern matcher on Non-Spam
The pattern matching engine can learn about your email traffic. Enable this control to allow the pattern matching engine to automatically learn about your email traffic from outbound messages and/or any emails you elect to send from the spam store. The engine is retrained every 250 email messages for efficiency, and is retrained up to a maximum of 50,000 emails, more than sufficient to learn about your email traffic.
