About the emergency Inbox
The Emergency Inbox allows users to send and receive messages if the company mail systems are offline, either for planned maintenance or due to an unexpected outage. During an outage, the Emergency Inbox is automatically populated (spooled) with incoming messages. (It does not show messages that were successfully delivered prior to mail delivery being impacted.) When systems resume functioning, the Emergency Inbox is cleared as messages retry to the mail server.
The Emergency Inbox can be used to send new messages as well as reply to received messages. Once email delivery has been restored any messages that were sent (both new and replies) are automatically delivered to the mail server.
What happens while the server is unreachable
During the outage, Proofpoint Essentials 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 to the sending mail server that we have been unsuccessful 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. The customer's mail server should be repaired as soon as possible to not lose email.
Emergency Inbox provides access to email in the event that a user's mail environment is unavailable. Once this occurs Proofpoint Essentials automatically begins to spool mail for the affected domain(s) and the Emergency Inbox will immediately show the spooled mail. Users are able to send new messages and reply to received messages. When an email is sent from Emergency Inbox it is treated like any outbound message. The email will show in another internal user’s Emergency Inbox. Users are unable to see messages that were successfully delivered prior to mail delivery being impacted.
