About the PMM Modes

You can set the operating mode for the Personal Message Management (PMM) system. The following operating modes are available:

Off - The PMM system including the portal is currently disabled. The system will not generate digests or provide the PMM portal for your users to manage their trusted senders.
Digest only - In Digest Only mode the PMM system will generate digests for your users to release and delete messages, but they will not be able to manage their trusted senders.
Lite - In Lite mode, your users will not be able to see a real-time list of their held messages or view other mailboxes. The PMM system will generate digests for your users to release and delete messages and they will be able to manage their trusted senders.
Full - In Full mode, your users will be able to see a real-time list of their held messages, view other mailboxes and manage their trusted senders.

Your license must have the PMM Portal feature to use PMM in Full mode. If you do not have this feature license, PMM can still be used in Digest only or Lite mode.

When you set the mode, advice will be displayed about the configuration settings that you will need to configure depending on the mode selected as described in the following table.

Mode	Peer enabled to produce digests	Peer enabled as portal	Active Directory / Domain member
Off	NO	NO	NO
Digest only	YES	NO	NO
Lite	YES	YES	NO
Full	YES	YES	YES

See the following for further information about the configuration settings:

You can select Full mode without generating digests. A warning will be displayed but the portal will function.
To use the PMM Portal in Full mode, you will need to update rules configured in upstream firewalls to allow ICMP, TCP and UDP traffic from the PMM Portal interface in addition to the default Gateway interfaces.
