Group Administrators have the ability to view and manage email for their own group within the Portal. They can release email and create rules that impact their Group's domain assignments.
For example, a Group Administrator can blacklist an email address at the Group level. That blacklist entry will apply to all users of all domains within that group. Users may elect to whitelist the same email address, which would take priority over the Group blacklist.
Group Administrators can also add, delete, and manage Portal Users within their own group. New users and email aliases can only be added for domains managed by the Mailborder server. For example, a Portal user cannot have the email address firstname.lastname@example.org unless gmail.com has been added in the Master interface as a managed domain.
