Hi Everyone, just looking at our spam filtering, Mail security & AV. Currently have an on Prem Exchange 2013 with ~60 Mailboxes mail is directly delivered to server. Mail flow is averaged at around 600 Sent and 1,000 Received per day We are wanting to look at adding some decent Anti Virus/Malware protection & Spam filtering. Symantec offer their "Symantec Mail Protection" app that installs on the exchange server. Trent Micro I believe offer a hosted mail exchanger to bounce exchange through. what are people's thoughts / experiences and recommendations?
