Blocking by headers only works if the message contains the header already. You'll have to examine an unmodified message to see what it contains. Likely your header_checks rule simply didn't match the header in the message. > At first I tried using the method explained on > http://www.cyberciti.biz/faq/howto-blacklist-reject-sender-email-address/ > but this could not allow postfix to restart. This is the easiest way to block a sender envelope address; that's the address logged by postfix in the maillog. The instructions on that website are incorrect. The quick fix for that website is to use smtpd_sender_restrictions rather than smtpd_recipient_restrictions. -- Noel Jones
