Well, no -- I am rewriting the sender address depending whether it
corresponds to LDAP object type A, type B, or not found -- but only
if the client is not in a whitelist ACL.

So use transport(5)? If I want to rewrite to form x, use transport x and
x_generic_maps, and then transport y and y_generic_maps for form y, etc?
That makes sense; and I see in ldap_table(5) a pattern for using LDAP
to drive transport decisions.
The next question is, how to make all this conditional on the ACL match?
I can see how to do this using two cooperating Postfix instances and an
access(5) map with FILTER. Is there a better way?
Thank you,
