Policy Quarantine Performance
Messages stored in policy quarantines use system memory in addition to hard-drive space. Storing
hundreds of thousands of messages in policy quarantines on a single appliance may cause a decrease in
the appliance’s performance due to excessive memory usage. The appliance takes more time to
quarantine, delete, and release messages, which causes message processing to slow down and the email
pipeline to back up.

Cisco recommends storing an average of less than 20,000 messages in your policy quarantines to ensure
that the Email Security appliance processes email at a normal rate.
