LuxSci has improved its email auto-responders (aka "vacation messages") by adding two new features:

• Scheduling: Users can now optionally specify a start and end date/time for their auto-responders to be enabled. The system will take care of turning them on and off and notifying the user when these events happen. Account administrators can also optionally choose to enforce a policy whereby all auto-responders must use scheduling.
• Reminders: Users can now optionally specify a date after which they will receive a daily reminder to turn off their auto-responders (until they do so).
