Hello, I've created multiple mailservers and I connected them with my ISPconfig, so now in Server tab I see 3 servers (one my default db,mail,apache,ftp server and two mailservers like mail1.hostname.com and mail2.hostname.com). My question is: How can I associate this external mailserver to specified exisiting domain on default server, where is ISPconfig installed? (In editing section on Mail domain tab I see just one server - default, but If I create new mailing domain, the server select is avalaible and I can choose from 3 servers)
But if I remove Email Domain, it will delete all email mailboxes. Can I just set sending over this new mailserver and recieving will still be on old mailserver? Because on new mailserver I don't have roundcube
