For DNS, configure both the servers are dns servers. Include both
these servers in your clients resolv.conf so that both the servers are
queried. If the primary server goes down, the client will query the
backup one, albeit with a small delay for the timeout.
For mail, setup the secondary mailserver as the backup mx. If the mail
cannot be delivered to the primary mail server it will be delivered to
the backup server.
For POP, i think you will have to use a virtual interface on your
primary mail server. And the backup server keeps polling the primary
one, when it is not able to connect to primary, it activates its the
virutal interface on itself.
Ensure that the mail is stored on a common storage accessible to both
so that they are always available.
my 2 cents.
