      I have transport front-end servers for domains:

      domain1.tld
      domain2.tld
      domain3.tld
      domain4.tld
      [..]
      domainX.tld

      I want to blacklist 1.2.3.4/24 only for destination domain3.tld (and
      reply with a 5xx if possible).

      What's the best way to handle this? On the backend server somewhere?
      But the backend server receives the mail from the frontend server, so
      simple blacklisting will not work.

      Any hint?

      R.
