I'm following the guide (Split DNS - Zimbra :: Wiki) and got to the part where I need to edit the /etc/named.conf file. I've edited the named.conf file to look like this:

Options {
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
forwarders { 64.0.x.x; };
include "/etc/rndc.key";
zone "mail-ca3-archive.usaepay.com" {
type master;
file "db.mail-ca3-archive.usaepay.com";

Here's my db.mail-ca3-archive.usaepay.com file:

; Addresses and other host information.
@ IN SOA mail-ca3-archive.usaepay.com. hostmaster.mail-ca3.archive.usaepay.com. (
10118 ; Serial
43200 ; Refresh
3600 ; Retry
3600000 ; Expire
2592000 ; Minimum
); Define the nameservers and the mail servers
IN NS 10.10.x.x
mail IN A 10.10.x.x
IN MX 10 mail.usaepay.com.

Changed the /etc/resolv.conf to reflect my Zimbra server as the primary DNS and also set the search path to Zimbra server. When I run /etc/init.d/named restart I get:

Stopping named: [ OK ]
Starting named:
Error in named configuration:
db.mail-ca3-archive.usaepay.com:4: no TTL specified; using SOA MINTTL instead
db.mail-ca3-archive.usaepay.com:11: NS record '10.10.x.x' appears to be an address
zone mail-ca3-archive.usaepay.com/IN: NS '10.10.x.x.mail-ca3-archive.usaepay.com' has no address records (A or AAAA)
zone mail-ca3-archive.usaepay.com/IN: not loaded due to errors.
_default/mail-ca3-archive.usaepay.com/IN: bad zone

I'm a newbie to this so please point me in the right direction. Thank you.
