Is there any way to create an exception or filter for certain email senders in the DLP Mail prevent ? NOT in every Detection Rule !!
The DLP network monitor has IP Filters, L7 Sender & L7 Recipients..... The DLP Web Prevent has Ignore request for Host/Domains or Agents.....The DLP Endpoint Agents have IP Filters & HTTP Filters.
We need to filter some internal email addresses ( Example : postmaster@domain.com ) and NOT BE redirected to DLP Mail Prevent for analisys.
The network infrastructure include Symantec Messaging Gateway appliance connected to DLP Mail prevent is reflect mode. The internal mail server infraestructure is Microsoft Exchange, and this server is generating the Postmaster notification to internet destinations.
