Rate Limit for Hosts
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.
