+/**
+ * Managesieve (Sieve Filters)
+ *
+ * Plugin that adds a possibility to manage Sieve filters in Thunderbird's style.
+ * It's clickable interface which operates on text scripts and communicates
+ * with server using managesieve protocol. Adds Filters tab in Settings.
+ *
+ * @version 1.0
+ * @author Aleksander 'A.L.E.C' Machniak <alec@alec.pl>
+ *
+ * Configuration (main.inc.php):
+

+$rcmail_config['managesieve_port'] = 2000;
+
+// managesieve server address
+$rcmail_config['managesieve_host'] = 'localhost';
+
+// use or not TLS for managesieve server connection
+// it's because I've problems with TLS and dovecot's managesieve plugin
+// and it's not needed on localhost
+$rcmail_config['managesieve_usetls'] = false;
+
+// default contents of filters script (eg. default spam filter)
+$rcmail_config['managesieve_default'] = '/etc/dovecot/sieve/global';
+

+// ':' delimiter, but creates folders with dot delimiter

+// envelope, environment, ereject, fileinto, ihave, imap4flags, index,
+// mailbox, mboxmetadata, regex, reject, relational, servermetadata,
+// spamtest, spamtestplus, subaddress, vacation, variables, virustest, etc.
