[SOLVED] Fresh Zimbra Install but Postfix and MTA will not start

[vernalcity]

After running the installation on RHEL5, everything seemed to have gone smooth except when zmcontrol status was ran, it reported-

mta stopped
postfix is not running

I am new to zimbra and everything I have tried has not worked. Any help or tips would be greatly appreciated.

Did you check if you had another MTA in your server?
Please run this command in your terminal:
telnet 127.0.0.1 25
if you've already another MTA, please remove it before installing zimbra.

That was it. I must not have realized it when I was setting up the server. Thank you for your help.
