Qmail and bounces

I have a mail server running a cluster of back-end stores (because no single 
server can handle the load) and Qmail-ldap for the front-end to send the 
message to the appropriate back-end machine.

The problem is that Qmail is accepting messages for non-existant destinations 
(IE mail for user@mydomain.com when there is not account named "user" in the 
LDAP directory).  Ideally Qmail would reject the message with a SMTP 550 
code.  However then Qmail will repeatedly try to deliver the message 
"locally" to the back-end machine but aborts every time because it's not in 
the LDAP (one message had 17 delivery attempts).

Any suggestions for what to do about this?
