Check listener status

In the listeners page, in the Last mail imported column, the date and time of the last email imported is shown.

If a listener is not importing emails you should check the email queue.

Check email queue

In the Archiver Dashboard, the central card shows the number of pending emails in the email queue. The email queue contains the emails the Archiver has not archived yet. 

If you have an inactive listeners and you have no emails in the queue, the Archiver is not receiving the journaling emails, so you should check the journal rule on your mail server. 

If you have many emails in the queue, the journaling is not working properly and you should check the deferred messages by clicking on the dashboard card.

Check the deferred messages

The deferred messages are the emails the Archiver has not archived yet. If you choose "No tenant" from the upper right dropdown, you can see the emails the Archiver is not able to assign to a specific tenant.  

To understand why the association could not be done, you can open the message details by clicking on the icon and check that the domain in the header X-Archiver-Sender-Domain or the IP address in the header X-Archiver-Sender-Addr are configured in one of the listeners of the tenant you want to assign the email to.
