OK - so I've never installed or worked with postfix before, so forgive me if this is fairly basic.
I have example.com all set up and working nicely with Google apps. Email comes and goes with no problem. I needed to provide a way for apps to email me, though, so I installed postfix.
It now emails out to all domains OTHER than example.com just fine, but if it tries to email an @example.com address and that address exists, it keeps the email local rather than pushing it out to the web and over to the gmail servers.
Any hints on how to fix this?
