I have installed postfix+dovecot+mysql. Everything works fine. But I need to do one specific thing:
If a user doesn't exist (e.g. idontexist@mydomain.tld), then the message needs to be forwarded to google apps. I need to the forward original message (like it was send to g-apps directly), not forward it to some bin@g-apps.
Can somene point me to the solution?
