/*
|
|
- * This an example spamfilter file, it contains several
|
|
- * real and useful spamfilters. This should give you an
|
|
- * idea of how powerful spamfilter can be in real-life
|
|
- * situations.
|
|
+ * This configuration file contains example spamfilter rules.
|
|
+ * They are real rules that were useful a long time ago.
|
|
+ * Since 2005 these rules are no longer maintained.
|
|
+ * The main purpose nowadays is to serve as an example
|
|
+ * to give you an idea of how powerful spamfilters can
|
|
+ * be in real-life situations.

-/* Guidelines on the 'action' field:
|
|
- * As a general rule we use 'action block' for any newly added
|
|
- * spamfilters at first, later on (after knowing about false
|
|
- * positives) we might change some to viruschan/kill/gline/etc..
|
|
+/* General note:
|
|
+ * If you want to use a \ in a spamfilter, or in fact
|
|
+ * anywhere in the configuration file, then you need
|
|
+ * to escape this to \\ instead.
