postfix not delivering locally but making MX lookup

    I'm trying to move the emails for from an old server to a new one. I thought I had set everything up correctly but there is still a big oopsie on the new server.

    the MX record is set to an appliance which scans and filters email and then forwards it to the server where the user accounts are located. Unfortunately, this new server is confused, instead of simply handing over the emails to the local delivery agent it does a MX lookup and forwards to the appliance which then relays the email again to the server and this loop goes on.

    the new server is called: and has (inside /etc/postfix/
    mydomain =
    mydestination = $mydomain, localhost.$mydomain, localhost

    what am I missing here? any pointers?

    Fixed by changing:
    mydestination = $mydomain, localhost.$mydomain, localhost
    mydestination =, $mydomain, localhost.$mydomain, localhost, localhost.localdomain
    no idea why declaring $mydomain was not enough but it works now after I have specifically added the domain.
