A solution to failover processing for automatic responder in a mixed server environment. The instant response system is part of mail delivery system without requiring every server in the cluster to be upgraded to the latest version. The auto-responder is installed in the router, as part of the mail delivery. In order to process messages delivered to the older version of servers seamlessly, the invention comprises an agent trigger which runs only on server start, an agent with a new type in the user mail file, which performs Out of Office functionality (similar to the current mail template functionality) or “failover” agent. The router processing for auto responder will enable the agent in the user mail file when it becomes activated (based on user specified configuration). The agent does not require any special security configuration because it is signed by the server. The email comes from the mail owner (intended recipient) setting the “Principal” field. The router auto responder processing marks each email it auto-responds (this happens before the email is written down to the user mail box, so this special marking does not require any additional I/O). It also stamps out of office profile document with date it performed the processing. |
