[Mimedefang] reject without creating a reject message

[Jobst Schmalenbach]

Hi.

I want to stop a message getting through.

I want to tell the sending mailserver that I do not want to accept
this (ie cancel) but without creating a "Undelivered Message".

Scenario:
~~~~~~~~~
I check the incoming mail and refuse to take the mail if the sender
comes from our domain, rejecting it with some "5.7.1" message.

In particular I want to stop emails coming through that have
"postmaster" and "mailer-deamon" etc from our domain.

Now the filter works fine and rejects all those email making it 
look like they come from our domain.


However if the spammer/worm/trojan now has an email address
that exists in our domain, than the email is rejected
but the person (unknowingly) receives an email of the rejection.


How can I reject the email without the "Undelivered Message"
being created? Do I just drop the mail? How I do that?



(Yes I know the "Undelivered Message" is created on the sending server).
