Mail Flow and the Cisco IronPort M-Series Appliance
If you include an M-Series appliance in your configuration, mail is sent to the
Cisco IronPort M-Series appliance from other Cisco IronPort (C- and X-Series)
appliances. A Cisco IronPort appliance that is configured to send mail to a Cisco
IronPort M-Series appliance will automatically expect to receive mail released
from the M-Series appliance and will not re-process those messages when they are
received back — messages will bypass the HAT and other policy or scanning
settings and be delivered. For this to work, the IP address of the Cisco IronPort
M-Series appliance must not change. If the IP address of the Cisco IronPort
M-Series appliance changes, the receiving C- or X-Series appliance will process
the message as it would any other incoming message. Always use the same IP
address for receiving and delivery on the Cisco IronPort M-Series appliance.

The Cisco IronPort M-Series appliance accepts mail for quarantining from the IP
addresses specified in the Cisco IronPort Spam Quarantine settings. To configure
the local quarantine on the Cisco IronPort M-Series appliance see the Cisco
IronPort AsyncOS for Security Management User Guide . Note that the local
quarantine on the Cisco IronPort M-Series appliance is referred to as an external
quarantine by the other Cisco IronPort appliances sending mail to it.

Mail released by the Cisco IronPort M-Series appliance is delivered to the
primary and secondary hosts (Cisco IronPort appliance or other groupware host)
as defined in the Spam Quarantine Settings (see the Cisco IronPort AsyncOS for
Security Management User Guide ). Therefore, regardless of the number of Cisco
IronPort appliances delivering mail to the Cisco IronPort M-Series appliance, all
released mail, notifications, and alerts are sent to a single host (groupware or
Cisco IronPort appliance). Take care to not overburden the primary host for
delivery from the Cisco IronPort M-Series appliance.
