May I have some suggestions on how to block certain outgoing email messages?
I want to block them based on an certain destination email domain.
Based on the knowledge I have (from several years ago),m this would be an Envelope rule.
But I see that there are "DLP" (data loss prevention) notifications available in this version of Ironmail (6.7.2).
DLP notifications only work if the box is connected to a DLP device such as the Mcafee Reconnex DLP.
To block outbound messages to a certain domain via envelope analysis:
1. Compliance -> Manage rules -> Add New
Monitored Field : Recipient
Quarantine Type: < the queue you want to quarantine messages to like "content analysis">
Action Value: if quarantining then set it to 0
2. Compliance -> Apply Rules -> Add New (if you already have an outbound rule then you dont need to add a new one)
Apply to: Global
Check the enable box for the rule you just created and then click submit.
That should take care of it.
Thanks for the clarification on the DLP feature. We may implement another vendor's DLP later this year, but we don't have McAfee's solution.
I will try your suggestion on blocking the outbound message.
