SMTP

Introduction

The SMTP service sends all mail generated by the appliance, typically in response to alerts as configured on the Alerts screen. The SMTP service does not accept external mail - it only sends mail generated automatically by the appliance itself.

By default, the SMTP service uses DNS (MX records) to determine where to send mail. If DNS is not configured for the appliance's domain, or the destination domain for outgoing mail does not have DNS MX records setup properly, the appliance can be configured to forward all mail through an outgoing mail server, commonly called a smarthost.

Properties

Changing services properties is documented in the BUI and CLI sections of Services.

When changing properties, you can use Alerts to send a test email to verify that the properties are correct. A common reason for undelivered email is misconfigured DNS, which prevents the appliance from determining which mail server to deliver the mail to; as described earlier, a smarthost could be used if DNS cannot be configured.
