I would like to know, if it is possible and which would be the best/correct way to create individual clients that are "mail account only" users, i.e. they should be allowed to create 1 to x mail accounts on a shared domain, say, which belongs to their reseller and on which other mail only clients might also create mail accounts. They might also be allowed to create mail aliases, forwardings, fetchmails mailing lists, etc. In essence, I want to provide a feature rich e-mail account to individuals. Big problem here is, they should NOT be able to create or (even worse) change/delete existing mail domains, since the are using a shared domain. I have not found a way yet to allow several clients to "use" a domain for mail accounts, while not allowing them to change the domain itself. Any ideas, thoughts on this?
