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. 

Max. 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.
