Hi Supose this escenario with ISPConfig. You have 3 server: 1 - Panel, Web server and DB 2 - DNS Server 3 - Mail Server You configure the 3 servers and work excelent, but you didn't install the mailman service in the mailserver, beacause in this moment wasn't necesary. Now you need install mailman and put it to work immediatly. What do you do? 1 - install a new mail server, install on it mailman, and join the server to the infraestructure of ispconfig and migrate your mail domians. 2- Install the mailman on the mail server that is working and reconfigure the ispconfig. If the option 2 is posible, How do I do that?
