It is not possible to switch Milter options in the middle of an SMTP session. That is why smtpd_milter_maps is indexed by the SMTP client IP address, and not by information that is received during an SMTP session. In theory software can be made to do arbitrary things, but in practice one has to limit the code complexity to guarantee some level of bug-free-ness. Maybe you can configure an exception for the sender's domain in the dkim milter configuration. Wietse
