I'm in the process of migrating my clients from ISPConfig 2 to ISPConfig 3 and I'm struggling with a few things concerning client templates: I can set the Max. number of e-mail domains and the Max. number of web domains. The problem is I don't know beforehand how many domains a client will register over time. How do I best utilize those fields? I can set both the Mailbox quota and Web quota. In ISPConfig 2 there is only one quota setting for available storage space and my hosting plans are set up accordingly. How does that translate to ISPConfig 3? As I don't know beforehand how my clients will use their storage space, i.e. how much they will use for e-mail and how much for web space, how do I specify those values?
