I need to configuire a Postfix/Cyrus installation and add mail domain filters to it. Currently the installation is setup for domain xyz.com and it get's all e-mails via another server acting as a mail relay.
What I need is when someone sends an e-mail (from within the network) to a particular domain it doesn't get sent via the mail relay. So to do this I add the domains in the "mydestination" field in the postfix conf file BUT if someone sends a mail to domain [email protected] I need it redirected/filtered to [email protected]
I couldn't find anything easy to understand on the net. Would appreciate some pointers.
