No. DNS lookups are done in individual SMTP client programs, not
in the central Postfix scheduler program.
The Postfix SMTP client has a few features that are keyed off the
remote server's IP address or name (for example, debug_peer_list
controls the logging level). This should be generalized so that
the sysadmin can control main.cf settings, too.
