Chapter 3 Setup and Installation
In this example portion of the
systemsetup
command, a public listener named
InboundMail is configured to run on the PublicNet IP interface. Then, it is
configured to accept all email for the domain
configured to accept all email for the domain
example.com
. An initial SMTP route
to the mail exchange
exchange.example.com
is configured. Rate limiting is
enabled, and the maximum value of 4500 recipients per hour from a single host is
specified for the public listener.
specified for the public listener.
Note
The value you enter for maximum recipients per hour you are willing to receive
from a remote host is a completely arbitrary value, one that is usually relative to
the size of the enterprise for which you are administering email. For example, a
sender who sends 200 messages in an hour might be considered a “spammer”
(sender of unsolicited bulk email), but if you are configuring the IronPort
appliance to handle all email for a 10,000 person company, 200 messages per hour
from a remote host may be a reasonable value. Conversely, in a 50-person
company, someone sending 200 messages in an hour to you may be an obvious
spammer. You must choose an appropriate value when you enable rate-limiting on
a public listener (throttle) inbound email for your enterprise. For more
information on Default Host Access policies, see

You are now going to configure how the IronPort C60 accepts mail by
creating a "Listener".
Please create a name for this listener (Ex: "InboundMail"):

Please choose an IP interface for this Listener.
