"Email Relaying" is using an email server to send email that did not originate on the email server.
System administrators can enable the feature under Setup | Email Administration | Email Relay Activation.
Why enable Email Relay?
You can set up email relaying for Salesforce-generated email by configuring Salesforce to automatically route email through your company's Simple Mail Transfer Protocol (SMTP) server. Keep in mind, SMTP authentication is not supported by Salesforce.
