■STA Mode — Use one of the following three modes for STA:
■Normal: This is the default mode and is recommended in most cases. The STA upper threshold is set to 85, and the lower threshold to 65. Any message with a metric 85 or above will be considered spam. A metric between 85 and 65 will be considered Maybe Spam, and will trigger an action if you have the Maybe Spam option enabled. A metric lower than 65 is considered legitimate mail.
■Aggressive: Increases STA’s aggressiveness to ensure more spam is caught, but also increases the possibility of false positives.The STA upper threshold is set to 80, and the lower threshold to 50. Any message with a metric 80 or above will be considered spam. A metric between 80 and 50 will be considered Maybe Spam, and will trigger an action if you have the Maybe Spam option enabled. A metric lower than 50 is considered legitimate mail.
■Lenient: Reduces the possibility of false positives, but more spam may get through. The STA upper threshold is set to 90, and the lower threshold to 80. Any message with a metric 90 or above will be considered spam. A metric between 90 and 80 will be considered Maybe Spam, and will trigger an action if you have the Maybe Spam option enabled. A metric lower than 80 is considered legitimate mail.
