Rate Limiting by envelope sender allows you to limit the number of email messages per time interval 
from an individual sender, based on the mail-from address. The Email > Reporting > Rate Limits page 
allows you to quickly identify individual senders of large numbers of messages. Use this report to help 
you to: 

Control spam from internal user accounts, for example in cases when a user's credentials are 
compromised and the account is used to send spam in bulk. 

Identify compromised user accounts. 

Limit out-of-control applications that use email for notifications, alerts, automated statements, etc.

Avoid damaging your organization’s online reputation and the attendant hassles resulting from this 
situation 

Rate Limiting settings, including “Rate Limit for Envelope Senders” settings, are configured on the 
Email Security appliance in Mail Policies > Mail Flow Policies. For more information on rate limiting, 
see the Cisco IronPort AsyncOS for Email Security Configuration Guide.
