Chapter 4 FortiOS Carrier : Duplicate message protection : Duplicate message actions
  
Duplicate message actions
When the Carrier-enabled FortiGate unit detects that a duplicate message has exceeded duplicate threshold, it can take any combination of the five actions you configure for the duplicate threshold.
 
Action
Description
Log
Add a log entry indicating that a duplicate message event has occurred. You must also enable logging for MMS Scanning > Bulk Messages in the Logging section of the MMS protection profile.
DLP Archive
 
 
All messages
Save all the messages that exceed the duplicate threshold in the DLP archive.
First message only
Save the first message to exceed the duplicate threshold in the DLP archive. Subsequent messages that exceed the duplicate threshold will not be saved.
Intercept
Messages that exceed the duplicate threshold are passed to the recipients, but if quarantine is enabled for intercepted messages, a copy of each message is also quarantined for later examination. If the quarantine of intercepted messages is disabled, the Intercept action has no effect.
Block
Messages that exceed the duplicate threshold are blocked and will not be delivered to the message recipients. If quarantine is enabled for blocked messages, a copy of each blocked message is quarantined for later examination.
Alert Notification
If the duplicate threshold is exceeded, the Carrier-enabled FortiGate unit will send an MMS duplicate message notification message.
