I have searched all the forum and the Internet for a solution to such problem.
When I make an account a domain administrator I would like it to be able to choose COS for this account in the limits given for the domain. Preferably it would be best to Account Type show just likfe for global admin.
As a service provider we set limits for our clients (to comply with the zimbra licence) i.e. 20 premium and 100 bussiness email accounts.
Setting listCOS, ... as in the previous posts doesn't solve the problem and even allows domain administrator to choose cos which has no set limit and go with the set over the limit.
Hope you can help me in this solution.
