Configuring SMTP Relay Hosts
AsyncOS periodically sends system-generated email messages, such as notifications, alerts, and Cisco
IronPort Customer Support requests. By default, AsyncOS uses information listed in the MX record on
your domain to send email. However, if the appliance cannot directly reach the mail servers listed in the
MX record, you must configure at least one SMTP relay host on the appliance.
