Response is a set of tools to handle automatic email responses, also called "Out of Office", "Vacation", or "Autoreply" messages. Response tries hard to do that the correct way, i.e. not responding to messages that should not be responded to. All of the validation code can be easily modified to suite your needs, but the project tries hard to ship sane defaults. It is designed for many virtual users and multiple mail servers, but works just fine for small deployments. Configuration and response state is stored in an RDBMS.
