Hello I need some clarifications on the verify_sender statement :
What I would like to do : When our MX receive an email from t...@domain.tld I would like Postfix perform a DNS lookup to verify that the IP address of the sender is really part of the domain "domain.tld" and if not reject the email from t...@domain.tld saying : "Your email has been rejected because your IP address is not in the domain "domain.tld" " Does verify_sender do that ? Thank you
