Need help with DNS record please

For one of my virtual host domains I would like to be able to direct all web traffic to an outside server.

So any traffic to: www.example.com or example.com or something.example.com

I would like to go to: something.example.net

where example.net is a domain not managed by me on another server.

I still want ftp and mail services for the example.com domain to stay on my local server.

This is for a shopify store and the directions at shopify.com say to add a cname record to the DNS record for the example.com domain which I tried but when I do and try to restart bind it throws an error until I remove the record.

Their example says that if I want to redirect the traffic for the subdomin shop I would enter this record:

shop CNAME example.myshopify.com.

where example is changed of course the the shopify account name.

That causes an error.

shop is an existing subdomain for example.com that I created through Virtualmin

I am using CentOS 5.3 and BIND 9.3.4

The current record looks like this:

$ttl 20M example.com. IN SOA ns1.example.org. hostmaster.example.org. ( 2009060239 5M 1H 1W 20M ) @ IN NS ns1.example.org. @ IN NS ns2.example.org. example.com. IN A xx.xx.xx.xx www.example.com. IN A xx.xx.xx.xx ftp.example.com. IN A xx.xx.xx.xx localhost.example.com. IN A 127.0.0.1 mail.example.com. IN A xx.xx.xx.xx7 example.com. IN MX 5 mail.example.com. example.com. IN TXT "v=spf1 a mx a:example.com ip4:xx.xx.xx.xx ip4:xx.xx.xx.xx -all" shop.example.com. IN A xx.xx.xx.xx www.shop.example.com. IN A xx.xx.xx.xx ftp.shop.example.com. IN A xx.xx.xx.xx m.shop.example.com. IN A xx.xx.xx.xx localhost.shop.example.com. IN A 127.0.0.1 webmail.shop.example.com. IN A xx.xx.xx.xx admin.shop.example.com. IN A xx.xx.xx.xx mail.shop.example.com. IN A xx.xx.xx.xx shop.example.com. IN MX 5 mail.shop.example.com.

Any help or pointers would be greatly appreciated :)
