The antispam-table.txt file that ships with the product, is appropriate for most users. However, you may need to alter this file if we have identified words as spam that you do not consider to be spam, or vice versa. For example, the word "mortgage" is identified as spam because in our tests, it occurred 370 times in non-spam, and 714 times in spam. However, at financial institutions, the word "mortgage" is a non-spam word that occurs frequently. In this case, you need to alter the antispam-table.txt file so that the antispam engine recognizes the word "mortgage" as non-spam.
