Here is my hosts file.

127.0.0.1       localhost.localdomain localhost
192.168.1.103  mail.MYDOMAIN.com mail

Here is my split dns setup

edit /etc/bind/named.conf.options

forwarders { 
xx.xx.xx.xx; xx.xx.xx.xx;   Now are these the nameserver numbers from router going to local internet provider?
};

Append to /etc/bind/named.conf.local

	// We are the master server for mail.MYDOMAIN.com
	zone "mail.MYDOMAIN.com" {
		type master;
		file "db.mail.MYDOMAIN.com";
};

create the zone file: /var/cache/bind/db.mail.MYDOMAIN.com

;
;       Addresses and other host information.

@       IN      SOA     mail.MYDOMAIN.com. mail.MYDOMAIN.com. (
                               10118      ; Serial

                               2592000 )  ; Minimum
;       Define the nameservers and the mail servers
               IN      NS      xxx.xxx.xxx.xxx  Is this internal ip address 192.168.1.103?
               IN      A       xxx.xxx.xxx.xxx   same as above then  192.168.1.103
               IN      MX      10 mail.MYDOMAIN.com.

# modify /etc/resolv.conf
change upstream name servers to your own IP:
nameserver xxx.xxx.xxx.xxx would this be internal ip again 192.168.1.103
# /etc/init.d/bind reload
# to test it, nslookup mail.MYDOMAIN.com should point to xxx.xxx.xxx.xxx

Here is what my nslookup looks like then

Server:         192.168.1.103
Address:        192.168.1.103#53

Name:   mail.tickus.com
Address: 192.168.1.103

root@mail:/home/nick#

Thanks Nick

Please don't post duplicate messages in the forum, I'll delete your other post.

Have you followed the wiki instructions? External DNS server should never point to an IP address on your LAN, to all intents and purposes they don't exist to anyone except your LAN.

everything worked and is good to go now. I had to add semi colons to the backends of this file pointed out in red here. Now everything is working.
