Unwanted relays

We have been having problems with sites relaying ip traffic off our
internet router. This is a DEC Brouter 90T1.
Why do these people do this? What is the benefit in bouncing traffic off
our Brouter address? How do they do it? And how do you configure the
Brouter to stop such relays?
We are reasonably well protected in sendmail to stop spammers relaying but
this ip relay is a new phenomenen. It is serious as it took over all our
bandwidth for 12 hours over the weekend and acted as a denial of service
to our users.
