STA (Statistical Token Analysis)
enabled), and local training. Since the database is not built for the first time until 12 hours after
installation, you can use this option to immediately rebuild the STA database.
Delete Training
Click the Delete Training button to remove all training material. You should delete all training
material if your ePrism system has been misconfigured and starts to treat "trusted" mail as
"untrusted" or vice versa.
STA Advanced Options
Click the Advanced button to reveal additional STA options. These options are for advanced STA
configuration only, and it is highly recommended that the default values be used. Modifications to
the default values may decrease STA accuracy and should be used with care.
Neutral Words
Neutral words are words that may or may not indicate spam. For example, a mortgage company
may want to build a neutral word list that includes "refinance" or "mortgage" because these words
show up quite frequently in spam mail. By adding them to the neutral word list, the likelihood of
this word suggesting spam would therefore be reduced to a neutral value.
• Default Neutral Words — Select the check box to enable the St. Bernard neutral words list.
This list helps prevent pollution of the STA database. It is recommended that you leave this
option enabled.
• Uploaded Neutral Words — Enables use of the uploaded neutral words list.
You must upload a file using the Upload Neutral Words button. The file must be in text format,
and contain a list of neutral words with one word per line. Uploading a new list will replace the
previous neutral words list.
