I have setup a multi server setup from the ispconfig3 manual, and was going to try and add roundcube to this setup. It is wanting me to add a database and which server would i add it to? Would that need to be added to the database server? and install the roundcube on the apache web server ? just trying to get my ducks in a row before attempting this.
It's up to you on which database server you install it as long as you add the correct database details in the RoundCube configuration.
