What happens once we run the suspendlistener command in IronPort CLI on both sender server as well. Where I can find this configuration in IronPort?

When suspended, the ESA appears unreachable for any communication trying to reach the suspended listener(s).

You can read more detail in my reply to another thread here : https://community.cisco.com/t5/email-security/when-outbound-private-listener-is-suspended-will-it-cause-queues/m-p/3690644

To confirm if the listeners are suspended, you can use listenerconfig from the CLI and it will show you which are suspended, or you can use the status command and review whether the System Status is Offline vs. Online. 

mail.esalab.local> listenerconfig

Currently configured listeners:
1. INCOMING (on Data-1, 1.1.1.1) SMTP TCP Port 25 Public (SUSPENDED)

Thanks!
