Friendly autoresponder/out of office

I need to be able to give users a simple way of setting up their own out of office autoresponders - without allowing them access to cPanel itself.
I have seen a relatively simple GUI which may have been an in-house custom job, but I cannot imagine that I am the only person to have wanted to achieve this - hence coming to the source of all knowledge about cPanel!
Any fixes or clues would be gratefully received.

 

Yeah - I did think of that, but it isn't quite what I was hoping for. Although they have ready access to the autoresponder I was hoping to find a solution that would allow a 'from' and 'to' interface for dates etc.

I know that I've seen this before - just can't find it!

Oh, well - maybe I should just point them to the url you suggest.
