Hi Michael,

Yes you need to modify the MX record in your DNS server to the new mail server you would host.
In the DNS you should have
IN MX 10 mail2..

This will ensure any clients in that domain will follow the MX record for exchanging mails.

Yes Michael, thats the only change you would be doing and restarting DNS services.

You need not modify named.conf file as it is purely to have the DNS forwarders and zone defined

I think you'll also need to increment serial number in the zone file. This number tells secondary name servers that data on primary has changed and needs to be refreshed.

Here is a sample SOA record in zone file.

xxx.xxx.xxx IN SOA xxx.xxx.xxx.xxx. xxx.xxx.xxx.xxx. (
123456 ; serial
900 ; refresh (15 minutes)
600 ; retry (10 minutes)
86400 ; expire (1 day)
600 ; minimum (10 minutes)
)

You should increment serial number by 1; change it to 123457. Then run the following command on the primary and secondary servers.

# sig_named restart
