This is a file to import into Outlook 2000 or 2003 to further reduce the amount of spam received after being filtered if it becomes necessary.
To avoid false positives we reject all spam that scores above 12 "spam points", but spam will be received that scores below this.
This filter lowers the threshold by moving all messages scoring more than 5 "spam points" and also ones with invalid dates into your spam folder.

Please note this filter only works in conjunction with the Shinymail mail service (or any Spamassassin setup with a similar configuration and fairly standard configuration)
