You could configure sendmail_path to a script that adds postmaster to
the recipients list before execing the real sendmail. This of course
assumes that you're not using Sieve, because then the sendmail_path is
executed for other reasons as well. Or alternatively you could read the
message body and see if it's a out-of-quota reply or not..

Same as above, make the script deliver the "out of quota" mail to user
(with quota disabled so it won't go to infinite loop).
