Here is the sit rep: I have my main server with Ubuntu 8.04lts and Postfix, mail.server.com I just commissioned a new server web1.server.com running ubuntu 10.04lts and postfix. My question is how do i make web1.server.com forward all mail for server.com to mail.server.com ?It always wants to try local delivery because of it's host name. I don't want it to forward all mail, just mail destined for server.com domain. Thanks for reading Beck
You can do this with Postfix transports. 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: 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/main.cf and add the hostname of the old server to the mydestination line so that the new server accepts the forwarded mails.
Thanks Falko, Although that is not exactly what I wanted to do, it did get me on the right track and was ablet to create a transport map for the new server to forward all of a certain domains mail to the old server. Code: echo "server.com smtp:server.com" >> /etc/postfix/transport postmap /etc/postfix/transport The old server is still up and controls the domain server.com. It will remain running. Thanks again.
