Outgoing SMTP Authentication<br />

SMTP Authentication can also be used to provide validation for an outbound mail relay, using a<br />

username and password. Create an ‘outgoing’ SMTP authentication profile and then attach the profile to<br />

an SMTP route for the ALL domain. On each mail delivery attempt, the Cisco <strong>IronPort</strong> appliance will<br />

log on to the upstream mail relay with the necessary credentials. Only a PLAIN SASL formatted login<br />

is supported.<br />

To use SMTP Authentication for all outgoing mail:<br />

Step 1 Click the Network > SMTP Authentication link. The SMTP Authentication page is displayed.<br />

Step 2 Click the Add Profile link. The Add SMTP Authentication Profile: SMTP Authentication Profile<br />

Settings page is displayed. Enter a unique name for the SMTP authentication profile. Select ‘Outgoing’<br />

for the Profile Type. Click the Next button.<br />
