2Set up MX records.
For users to send and receive mail over the Internet, make sure DNS service is set up with the relevant MX records for Mail service:
ÂÂ If an ISP provides DNS service to your network, contact the ISP and have them set up MX records for you. Your ISP needs your mail server’s DNS name (such as mail. example.com) and your server’s IP address.
ÂÂ If you use Mac OS X Server to provide DNS service, create MX records as described in “Configuring DNS for Mail Service” on page 21.
ÂÂ If you do not set up an MX record for your mail server, your server might still be able to exchange mail with other mail servers. Some mail servers will find your mail server by looking in DNS for your server’s A record. (You probably have an A record if you have a web server set up.)
Note: Your mail users can send mail to each other even if you do not set up MX records. Local Mail service doesn’t require MX records.
3Configure incoming Mail service.
Mail service has many settings that determine how it handles incoming mail. For instructions, see “Configuring Incoming Mail Service” on page 29.
4Configure outgoing Mail service.
Mail service has many settings that determine how it handles outgoing mail. For instructions, see “Configuring Outgoing Mail Service” on page 26.
5Secure your server.
If your server exchanges mail over the Internet, make sure you’re not operating an open relay. An open relay is a security risk and enables junk mail senders to use your computer resources for sending unsolicited commercial mail. For instructions see “Restricting SMTP Relay” on page 31.
