Hello Community we were tasked at routing all outbound email from our mail relay postfix server through an Anti-SPAM gateway and this introduces a requirement to insert a custom header with a unique value ( shared by the Anti-SPAM vendor ) to let email relay thorough them.
so we want to insert a header X-AUTH-TOKEN : xyz123 in every email leaving our postfix server. Could any one of you please suggest how we can achieve this . -- Sent from: http://postfix.1071664.n5.nabble.com/Postfix-Users-f2.html
