MailVault v3.4.17 is available.

This release modifies and enhances the sub-admin role.

A sub-admin is no longer allowed to delete messages. Additionally, we have introduced a number of privileges, that may optionally be granted to a sub-admin. This adds to overall security, offers greater flexibility to accommodate various organizations policies and overall makes the sub-admin role more convenient.

You can upgrade your MailVault installation by going to:

Settings > Core > Auto updates and click on Check for updates

Then simply follow the on-screen instructions.
