CA DLP Tuesday Tip Configuring DataMinder with Postfix, published 11 September 2012 by Simon (Mark) Biddle Snr. Support Engineer.

Sendmail is a mail transfer agent (MTA) originating from the open source and Unix communities. Postfix is intended to be an easy-to-administer, secure alternative to the Sendmail MTA. Both are used to route and deliver email and provide additional services such as protecting organizations from unwanted messages (spam). CA (DLP) DataMinder integration with Sendmail and Postfix is implemented through its Milter MTA agent.

Please also note that by default wgnmilter config file is "Off" and this needs to be changed to "On"
