Greetings,
With the introduce of Exchange Server 2013 along with its architecture, Microsoft has moved Transport services / roles to Mailbox Server Role. well, when it comes to anti malware / anti spam and viruses , Microsoft recommends deploying them on Mailbox Server role, while on CAS, not necessarily be deployed as long as messages are not inspected on CAS Servers.
While some articles say the opposite, and mention configuration of Anti malware ,etc.. on CAS Servers.
What is the best practice for deploying anti malware / spam / virus Software on CAS, and what is the best recommended software for messaging and OS level protection, say Symantec for example.
Thanking you
Jamil
