The simplest way is to add an A record that defines the domain name as
a host with the same IP address as the mail host. Here's what it looks
like in our named file, where frank.borland.com is the mailhost. Note
the games played with $ORIGIN to change the default domain properly.
I tried using an MX record to define borland.com, but some sites would
not send mail to it properly until I did this.
