Move mail server

Hello

I have one server with ispconfig, where are all services,
but now i bought new one and want to move mail service to new slave server
i prepared slave mail, server as described here

http://www.howtoforge.com/installing-a-multiserver-setup-with-dedicated-web-email-dns-and-mysql-database-servers-on-debian-5.0-with-ispconfig-3

but what changes should I make on master site. ?

thanks

 

You must change the MX records of your domains that you moved to the new server.

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

 

thanks for answer
but i wonder what should i change only in ispconfig configuration

in config there are

$conf['modules_available'] = 'dashboard,mail,admin,sites,monitor,client,dns,help';

$conf['interface_modules_enabled'] = 'dashboard,mail,sites,dns,tools';

should i remove mail form here ?

should I remove any sumlinks from
plugins-enabled
mods-enabled
?

something else ?

 

If you disable the mail module, you won't be able to configure mail on the slave... Just change the MX records and don't configure any new email accounts on the main server.
