I might have missed a couple of installments, but didn't someone
demonstrate that your problem is that you're accepting all mail to
postmaster@<yourdomains> in the ACL, but then not accepting the same
mail in your routers.... the 'problem' would be got round if you
removed the blanket 'accept' for postmaster in your RCPT ACL I would
have thought...
... but then you're back with the problem with what to do with your
postmaster mail. But at least you won't be generating backscatter.
