Are you saying that you don't have a message = option with the above
text in any of your ACLs? If so, then it isn't your server
generating the rejection, it's some server you are attempting to send
to. Which would mean that the problem is that *your* server doesn't
accept <postmaster@yourdomain> addresses, not that you are insisting
that other servers do.
