I had a ditto system sometime ago - only the servers were sendmail.
What I did was to write a Milter on the front server that would check
on the back server for users via a SMTP connection using VRFY, and
cache the results for a configurable amount of time (mine was 6 hours,
worked well).

Maybe you could do the same with a courierfilter.
