Redirecting email to another server

    Is it possible to setup a redirect on one Ispconfig machine to divert all incoming email to another server? I am migrating multiple domains, one by one, from one Ispconfig server to another one and want to setup identical accounts on the backup machine.

    Once I have all setup and working, then I would make all the DNS changes and retire the old computer.

    On the old server, create a Postfix transport now so that all emails are forwarded to the new server (for the time until the MX records of your domains have switched to the new server):
    Code:

    Code:
    echo "*  smtp:[<IP address of new server>]" >> /etc/postfix/transport
    postmap /etc/postfix/transport
    /etc/init.d/postfix restart
    On the new server, open /etc/postfix/local-host-names and add the hostname of the old server at the bottom so that the new server accepts the forwarded mails.

    Thanks for the reply.
    Is there a way to do this per domain basis?

    Yes - take a look at
    Code:
    man 5 transport
