...but keep in mind that some Spammers write in the headers exactly this string to pass spam-filters. If you cant WHITELIST AUTH or certain IP-ranges your only choice is to use CMD-space in combination of filters. For example if SNIFFER + CMDSPACE fails or if CMDSPACE and a filter file that contains some forreign countries you can't be sure that none of your customers will never send a legit message from there. Maybe you have all you client configurations set to use a certain host name as outgoing smtp-server while the official host name in the MX-Records for all incomming messages is another one. In this case you can point the outgoing smtp IP to another machine and set up there a SMTP-relay that forwards all messages to your actual mail server. Then you can whitelist all messages coming from the relay servers IP. But now you have to solve how to configure the relay server without becoming an open relay....
