Postfix - Configuring a 'do-not-reply@domain.com' address

Last Modified: 2013-12-17
Hi, I am having trouble configuring a 'do-not-reply' address for outgoing mail using Postfix on RHEL.  The purpose is a php form contained within a website on the server, which will email respondants to the form upon completion.  I have now managed to allow the mail to be relayed to our mail server which allows it to go outbound, and have also configured the domain from which the mail looks like it is sent.  My problem is that I cannot find a way to change the user from 'apache @' to 'do-not-reply@'.  I have read that aliases can be used, but this seems a little complex for the purpose.
There are other websites on the server which I do not want to impact, although as far as I know they will not have any reliance on Postfix.
If anyone can point me in the right direction it would be greatly appreciated, thanks!
