21.3 Spamfilter setup
There are two advanced options for spam detection.
Local tests only
This setting controls whether online databases with spam related information
will be consulted or not. When this box is checked no network traffic will be
generated, making the spam detection somewhat less effective, but
considerable faster.
Spam-drop score
This number reflects the score used by the spam-detection system to decide
whether to block the mail or let it pass. Mail with a high spam chance get a
high value. So a low value here will treat mail easier as spam. In the mail
headers of any mail with a spam score above 3.0, this score will be printed.
