+Please follow these steps if your mailserver is used as a backup MX for some
+(or all) of your domains.
+
+Note: The setup described in this file only checks the domain, not the full
+mail address. 
+You should use "reject_unverified_recipient" in your postfix config or setup
+"relay_recipient_maps" with a list of valid mail adresses on the primary mx
+to avoid that your backup MX accepts mails for non-existing recipient adresses.
+Without this, your backup MX might become a backscatter source.
