Hexamail Guard Administration Guide - User - Archiver
User Archiver Settings
You can selectively enable web-interface archive discovery for some users and not others.
Users can be assigned multiple additional email addresses for which they can retrieve archive results, e.g. an administrator may specify *@* in this list.
This is in addition to their primary alias list, but solely affects which email they see in the archive: Hexamail will not automatically accept email to these addresses as with the primary alias list
