Hi All.

I see that inside roundcube there is a Global Address Book, I need to make a user (can be postmater) can manage that address book and the groups in it.

I need to create groups or mailing lists and that user is the only one who can create, modify, delete in that global notebook and its groups. But all other users can see it and use it to send emails to contacts in those groups.

What should I do for this that I need? I see in the settings for that address book writing and other details are disabled. I need a user to be able to manage it without difficulty.

There is a plugin called "globaladdressbook" for roundcube, should I install this plugin or modifying the existing configuration can my problems be solved?

Thanks a lot.
