[Exim] Generate message at deliveries

Hello there,

I have to get Exim to generate an email to the sender of a message when
it's delivered, telling the user the status: delivered, bounced, timeouts...

I got an idea reading shadow_transport, but it doesn't work with remote
deliveries. The other idea is to make a secondary transport conditioned
to a first one, and pipe that through a perl script or something like
that... maybe watching the log... well, got the picture, right? :)

So, any idea?

thanks
