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.
