Configuring Mail Policies
Managed Exceptions
Because the iterative processing of each splinter message impacts performance, Cisco recommends
configuring your content security rules on a managed exception basis. In other words, evaluate your
organization’s needs and try to configure the feature so that the majority of messages will be handled by
the default mail policy and the minority of messages will be handled by a few additional “exception”
policies. In this manner, message splintering will be minimized and you are less likely to impact system
performance from the processing of each splinter message in the work queue.
