Google Group owners are able to moderate the messages sent to their members to protect them from junk mail. Moderation is not active by default and should be set up as appropriate by the group owner.

Owners and managers are generally granted permission to determine which messages should be allowed to be sent to group members. Messages held for moderation will appear in the “Pending Messages” queue until a decision is made about their distribution.

Default moderation options:

  • Moderate no messages (all messages get sent to members)
  • Moderate all messages (all messages are placed in pending until approval)
  • Moderate messages from non-members (messages from members are sent through but messages from non-members are held pending)

Note: Any message that Google suspects might be spam will also be held in “Pending Messages”.

Rejected message settings:

The Rejected Author notification setting determines whether or not the sender of the rejected message receives a message notifying them that their message did not go through. Options include:

  • Do not notify
  • Default rejection message
  • Custom rejection message
