Typical Network Configuration Incorporating the Cisco IronPort M-Series Appliance
Large corporate data centers can share one Cisco IronPort M-Series appliance
acting as an external IronPort Spam quarantine for one or more Cisco IronPort C-
or X-Series appliances. Further, remote offices can be set up to maintain their own
local Cisco IronPort appliance quarantines for local use (using the local IronPort
Spam quarantine on C- or X-Series appliances).

Spam and suspected spam (depending on your mail flow policy settings) is sent
to the Cisco IronPort M-Series appliance’s Spam quarantine. End users may then
access the quarantine and elect to delete spam and release messages they would
like to have delivered to themselves. Messages remaining in the IronPort Spam
quarantine are automatically deleted after a configurable amount of time (see the

Mail Flow and the Cisco IronPort M-Series Appliance
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
(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
