+The dovecot antispam plugin watches a defined spam folder (defaults to
+"SPAM"). Instead of moving mail into special folders or forwarding
+them to special mail addresses for retraining, the plugin offers two
+actions for the user:
+
+    1. moving mail out of the SPAM folder and
+
+    2. moving mail into the SPAM folder.
+
+The dovecot plugin watches these actions (and additionally prohibits
+APPENDs to the SPAM folder, more for technical reasons than others)
+and tells the spam classifier that it made an error and needs to
+re-clas- sify the message (as spam/not spam depending on which way it
+was moved.)
