This is an educated guess -- as i've never had a need to do this. . . turnoff 
the local_recipient_maps by setting it to null in the main.cf -- this will 
allow postfix to receive any mail regardless of user or domain - set your 
luser_relay value to the local user you want to receive the mail. .

BREAKING THE RFC NOTE - by doing this you are breaking several mail rules. If a 
sender mispells the name of a user they will not get a bounce back . . other 
notifications may also get lost.

The better way to handle this is to provide your backup server with either a 
method to verify user's existence -- a hash list of ldap for instance . . .

good luck - steve
