how to test outbound communication is working fine

[amahmud01]

Hi

what is the CLI command to test the email flow from the IronPort to outside domains?

Hey Amahmud01,

To test outbound connectivity I would do a telnet to an external outside mail server from the ESA.

Log into the ESA

nslookup gmail.com mx

then telnet to the mail exchanger of gmail for example, and verify if it connects

telnet x.x.x.x 25

EHLO yourdomain.com

If that connectivity works, then the mail should transfer barring any rejection due to IP reputation/invalid SMTP codes.

Regards,

Mathew
