Defining your email server with a DNS mail server record
A DNS mail server record, known as mail exchange (MX) record in standard DNS, defines the server
responsible for handling email. Use a public mail server record to point external mail systems to the
address for your domain’s mail server, usually the outside address of the security gateway. Use a
private mail server record to control the routing of internal mail to internal mail servers.
