Try using the "Monitor -> Delivery Status" section in the GUI interface. It sheds some light on soft bounces(4##) and hard bounces(5##) statistics. From that page you can click on the "Help" button on the top right hand corner for more info relevant to that page. Also, on that page, you can click on the destination domains to get more detailed info on that domain.
From the CLI, here are some commands that give you similar results:
Here are some CLI commands that you may find useful in diagnosing the mail flow on your Ironport appliances:
NOTE: For the commands, you can type "help resumelistener" and get brieft explanations on what it means and does.
Resumes receiving. You may specify one or more listener names which will only resume those listeners.
Use the keyword "all" to resume all listeners.
1. workqueue rate 60
- This will show you the rate of your pending workqueue and mailing going inbound/outbound in the scanning process for every 60 seconds.
2. tophosts --> Active Recipients(1)
- This displays messages in the delivery queue. Messages here have already been scanned and is waiting to be delivered.
- This provides some information about the mailserver and if they are up or down.
4. suspendlistener ---> select the inbound listener
- This command should only be used if you see a high queue on one of your Ironport appliances. A high queue would be over 1000 messages, sustained for a long period of time. Suspending the inbound listener on the appliance will allow the mail to process quicker and let the other appliance assist in the processing of mail traffic. You should contact Ironport Customer Support at this time so that we can assist in diagnosing the reason for the workqueue backup.
5. resumelistener ---> select the listener that is in suspension
- This resumes a listener that was previously suspended. Resuming a listener will allow it to start receiving mail again.
- This command allows you to pause delivery of mail to the destinations. Note, this will suspend all mail delivery, not just one select domain.
- Resumes the delivery for all mail.
- To delete, activate, de-activate, create new message filters
- grep allows you to search for entries in the mail_logs
grep -i "email@example.com" mail_logs
grep -i "spam" mail_logs
-i means ignorecase
- Will try to immediately re-send all mail that was previously deferred and sitting in the delivery queue.
