Abstract
The present invention provides an improved system and method for disaster recovery and management of an email system. The system includes a deferral monitor that detects when a failure occurs in a client'"'"'s email system, and a mailbox creation process and automatically creates mailbox accounts for the affected domains that queue incoming mail while the failure is repaired. This ensures no email is bounced because of the unavailable mail servers. Once the email servers are reconnected, the system forwards queued email to the client in a “flow-controlled” manner until all email is delivered. The system may further include a web mail interface that allows the client to maintain email functionality until the failure is repaired. The system may also include a message switch that filters all email for policy and content rules, spam and viruses before passing the email to the client.
