Per-Mailbox Access Control / Mailbox Isolation

Introduce granular mailbox-level permissions, such as the ability to hide or lock specific mailboxes from other users / Restrict access to password resets or content for selected email addresses / Allow forwarding-only roles or email routing control without full inbox access / Provide an audit trail of mailbox access/resets.

Right now, you can either completely give access, or completely remove it. 

If implemented, this feature would allow companies like ours to avoid migrating sensitive mailboxes to third-party providers like Zoho and instead keep everything unified within ScalaHosting, which is our preference.
