144 Message Security for Google Apps Administration Guide
For information on configuring notifications, see “About Notifications” on
page 149. See below for recommended configurations, as regards the Message
Center:
Message Center Status Recommended Notification Status
Enabled for the org Enable Welcome New User This notification is mailed
automatically to new users whose Message Center
Access is enabled (via the Default User’s User Access
settings). It contains the URL and password for logging
in to the Center. Enabling this notification is how you
provide users with their necessary login information.
Enable New Spam (Quarantine Summary) This
notification is sent periodically, listing the user’s
recently quarantined spam. It also provides a
convenient link to their Message Center.
Enable First Spam This notification is sent when the
user’s first filtered message is quarantined in their
Message Center.
Disabled for the org Disable Welcome New User Otherwise, new users
will get login information to the Message Center, but
not be able to log in.
Enable or Disable New Spam Enable, if you users
should be able to review Subject lines of quarantined
messages by email, and forward any legitimate
messages to their Inbox. So users can’t try to access
the Message Center, disable Message Center Subject
Links for the org (see “Prevent Users from Opening
Quarantined Messages” on page 142).
Disable this notification if you don’t want users to
manage their spam at all, but you intend to manage it
for them via the Administration Console.
Enable First Spam only if New Spam is also enabled.
