Configuring and Administering the BIND Name Service
Configuring a Primary Master Name Server
host is down or inaccessible. The preference field
specifies the order a mailer should follow if there is
more than one mail exchanger for a given host. A low
preference value indicates a higher precedence for the
mail exchanger.
In the example below, mail for rabbit should go first to
rabbit.div.inc.com. If rabbit is down, its mail
should be sent to indigo.div.inc.com.
See “Installing and Administering sendmail” on page
153 for information on sendmail and how it uses the
name server’s MX records for mail routing.
