I'm a bit confused. These are ldap parameters, right? So I'd change main.cf 
from:

canonical_maps = regexp:/etc/postfix/canonical

to

canonical_maps = ldap:/etc/postfix/canonical

So postfix would do an ldap lookup to rewrite the headers. But then would it 
do a second ldap lookup to validate the recipient?
