Out of Office and Email Notification

We have this component now integrated into production. Before we implemented this if user A submits to user B, user B would get an email. Now if user A submits to user B, and user B is out of office, user C get the worklist item but user C does not receive an email. As well, as part of the InfoPath client event a SPS task items is also generated and again, user C does not have a task added to SPS. I believe I understand why. Is there a way to extend the out of office functionality such and email notification can be sent to the user C?

Thanks...Jason
