Cisco Cisco Email Security Appliance C680 User Guide

Outbreak Filters — Because Cisco IronPort’s Outbreak Filters feature is used 
to quarantine incoming mail, this feature has been disabled on the C350D. 
Chapter 11 is, therefore, not applicable.

SenderBase Network Participation capabilities — Because SenderBase 
Network Participation reports information about incoming mail, this feature 
has been disabled on the C350D appliance. Chapters 8 and 12 are, therefore, 
not applicable.

Reporting — Reporting is limited. Some reports are not available, and the 
reporting that does occur is set to run at a very limited level due to the 
performance issues.

RSA Data Loss Prevention — RSA DLP scanning for outgoing messages has 
been disabled on C350D appliances.

The totals shown in the Email Security Monitor Overview report for 350D 
appliances may erroneously include spam and suspect spam counts although 
these features are disabled for the C350D appliances.

which are of interest to C350D users.
