Cisco Iron Port - Unknown Event

From the admin guide, these steps need to be followed.  The log above does not look like the sample in the admin guide, so it probably needs a parser adjustment if all the steps have been followed: 

Syslog

1. Log in to your Ironport Mail Gateway device manager with administrator privileges. 
2. Edit the Log Subscription settings.
3. For Log Name, enter IronPort-Mail.
   This identifies the log to FortiSIEM as originating from an Ironport mail gateway device. 
4. For Retrieval Method, select Syslog Push. 
5. For Hostname, enter the IP address of your FortiSIEM virtual appliance.
6. For Protocol, select UDP.
