I have a Linux VPS and a hosted exchange server from somewhere else. I can receive emails from my exchange server if I point mx entry on my VPS to exchange server. But if I point mx entry, same account on my VPS does not get emails. Yes this is how it works, I know. Is there a way to get emails on both remote exchange mail server and my local VPS? Is there any DNS settings for this? Basically I want to do something like mirroring.
