Override SMTP 
Banner Host Name

By default, the appliance will include the hostname 
associated with the interface of the listener when 
displaying the SMTP banner to remote hosts (for 
example: 

220-

 ESMTP

). You may choose to 

override this banner by entering a different hostname 
here. Additionally, you may leave the hostname field 
blank to choose not to display a hostname in the banner. 

Rate Limiting: 
Maximum Recipients 
per Hour 

The maximum number of recipients per hour this 
listener will receive from a remote host. The number of 
recipients per sender IP address is tracked globally. 
Each listener tracks its own rate limiting threshold; 
however, because all listeners validate against a single 
counter, it is more likely that the rate limit will be 
exceeded if the same IP address (sender) is connecting 
to multiple listeners.
