My understainding is Exchange 5.5 doesn't do the milter-ahead thing.  To get
a user list out of 5.5, I'd have to export LDAP data, massage it, etc.
There's a FAQ or a MAQ on setting it up, but it entails bones, feathers,
masks and rattles and I've never felt inclined to tackle it.  Exchange 2003
can easily be set up to reply to an address challenge apparently so when
we're on it, milter-ahead should respond appropriately.  Can't wait...
