Emergency Inbox

The Emergency Inbox service was created for mail continuity as indicated on the linked page. Users that can access this feature are able to use a web mail based mail feature while their mail server is down.

The Proofpoint Essentials service will continue to try and check the customer's mail server, as per the standard set-up. As we are unable to relay the email from our system to the customer's server (as it is down), we are required by RFC to send a deferral notice back to the sending mail server that we have not been successful in delivering the email. As long as the customer's mail server is down, we will continue to send deferral messages for some time (we set 30 days) then bounce the message back to the sender. It is important that the customer mail server be brought back as soon as possible to not lose email.


Emergency Inbox is used to provide users access to email in the event that their mail environment is unavailable. Once this occurs Proofpoint Essentials will automatically begin to spool mail for the affected domain and the Emergency inbox will immediately begin to show the spooled mail. Users are able to send new messages as well as reply to received messages. When an email is sent out from Emergency Inbox – new email, reply to email – it is treated like any outbound message. So the email will show up in another internal user’s Emergency Inbox.  Users are unable to see messages that were successfully delivered prior to mail delivery being impacted.

For testing the Emergency Inbox, you can deadhead the SMTP delivery address by changing the delivery server to This should start spooling and deferring the messages putting them in the Emergency Inbox.

  • To accomplish this go to Company Settings -> Domains 
  • Click on the Pencil Icon to the domain your looking to change. 
  • In the SMTP Delivery destination put in or any other bogus IP address
