An MX record is an entry in a DNS database that defines the host willing to accept mail for a given machine. Your MX records must route email through Cloud Email Security to your mail server.
United States - smtp02-in.isheriff.com
Canada - smtp01.ca.isheriff.com
Germany - smtp01-in.isheriff.com
South Africa - smtp01.za.isheriff.com
This would route all your incoming mails through Cloud Email Security and then after scanning those mails will be delivered to your internal mail server.

Note
Email Security must be configured before you update your MX record. |
