With the migration of the Marshall Email System's Spam Security service to Barracuda Cloud, the on-site appliances had become redundant. At 10AM 12/17/2019, we shut down the 3 on-premises barracuda appliances. The units are still in place in the highly unlikely event that we need to reactivate them for some reason. These units will be removed later after a period of time to verify that there are no unknown services attempting to use them.
Impact: Little to none. There were no known services routing mail through the on-premises appliances.
Affected Applications: None known
