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?
