Maintain Auto-Responder Remotely

[Shanks]

What is the preferred way to allows Windows-people to be able to turn
their .procmailrc on and off without them knowing what they're really
doing,  and also being able to upload an autoreply text file into their
home directory. I don't want to allows shell access and/or require them
to have any Linux knowledge but I don't want to have to get them to
email me their autoreply and for me to have to set it up each time.
