How do I configure postfix master to forward all email to an email server ?

Let's say I have 2 machines in my network (sitting behind a firewall):

1. An email server (serves
2. A SLES (SuSE Linux Enterprise server) server.

I have an application running on the SLES that sends email. The app uses postfix master to send email.

Currently, if my app sends an email to, the mail is successfully delivered via the email server.

However, if my app sends an email to, postfix/smtp complains that the is unreachable. I have opened up the firewall so that my SLES server can send email out to the outside world on port 25.

Does anybody know I can configure postfix master so that *ALL* email is sent (or relayed) via my email server?

Thanks in advance.

This is now fixed. I changed my default gateway on the SLES server to point to the firewall. Now, the email server can find all domains (e.g.,, etc)
