 ======Postscreen Plugin Documentation======
-TODO
+Plugin allows to use Postscreen with Postfix on i-MSCP.
+The Postfix Postscreen daemon provides additional protection against mail server overload. One Postscreen process handles multiple inbound SMTP connections, and decides which clients may talk to a Postfix SMTP server process. By keeping spambots away, Postscreen leaves more SMTP server processes available for legitimate clients, and delays the onset of server overload conditions.
+===== Attention =====
+Please read the [[http://www.postfix.org/POSTSCREEN_README.html|Postfix Postscreen Howto]] before installing this plugin.
+If you use this Plugin your MUA clients should not submit mail via SMTP service on TCP port 25 because that is used for the Postscreen daemon with all the checks.
+Instead your MUA clients should submit mails via SUBMISSION service on TCP port 587 or via SMTPS service on TCP port 465 which both require client authentication.
+===== Requirements =====
+	* i-MSCP versions >= 1.2.3
+  * Postfix version >= 2.8
