Hi. I have a CentOS server (server.domain.com), I have installed ISPConfig with all service: DNS, Postfix, Spamassasing, Dovecot, IMAP, SASLAUTH, APACHE, PHP, MySQL, all..... so in this server I has some accounts, but I need configurate a new server (server2.domain.com), Can I manage the new server from the ISPConfig Control Panel of "server.domain.com" ??? or need use the Control Panel from the server2.domain.com ???... My principal idea is use only one SMTP service (postfix) for all my servers, so all my server it will "server.domain.com" like relay host. But: "how can set all users in the postfix smtp for other servers ??" Regards !
