Cisco Cisco Email Security Appliance C190 Release Notes

Enabling the IronPort Spam Quarantine on-box for a C-Series or X-Series appliance causes a minimal 
reduction in system throughput for nominally loaded appliances. For appliances that are running near or 
at peak throughput, the additional load from an active quarantine may cause a throughput reduction of 
10-20%. If your system is at or near capacity, and you desire to use the IronPort Spam Quarantine, 
consider migrating to a larger C-Series appliance or an M-Series appliance.

If you change your anti-spam policy from dropping spam to quarantining it (either on-box or off-box), 
then your system load will increase due to the need to scan additional spam messages for virus and 
content security. For assistance in properly sizing your installation please contact your authorized 
support provider.
