DNS/Mail Question

I now have two servers, both using the same domain name as the hostname...with different subdomains.

Here is how I have things setup. I know the DNS is not optimum. These domains are examples, and not really my domains, obviously.

Server 1 (alpha.server-host.com) IP is 123.45.67.89
Server 2 (beta.server-host.com) IP is 987.65.43.21

Server 1:
Hostname: alpha.server-host.com

server-host.com. 14400 NS ns1.server-host.com.
server-host.com. 14400 NS ns2.server-host.com.
server-host.com. 14400 A 123.45.67.89
localhost.server-host.com. 14400 A 127.0.0.1
server-host.com. 14400 MX 0 server-host.com
mail 14400 CNAME server-host.com
www 14400 CNAME server-host.com
ftp 14400 A 123.45.67.89
alpha 14400 A 123.45.67.89
beta 14499 A 987.65.43.21

Server 2:
Hostname: beta.server-host.com

My problem is that on beta.server-host.com, I can not send email to other domains on the server, nor to domains on alpha.server-host.com. alpha.server-host.com cannot send email to beta.server-host.com, but can send to domains on the same server.

What am I missing? There are no DNS entries for 'server-host.com' on beta.server-host.com, and I think that has something to do with the problem?
