Hi all, I have a postfix instance dedicated to being the main MX (IN). I normally use other postfix instances for sending emails out (OUT).
Of course, even this "IN" instance needs to send emails out, mainly bounces. Now I am also implementing forwarding rules: "if you receive an email destined to this address, than forward it out to this other email address". Other addresses are @gmail.com, @msn.com, etc... In order to do that "right" I also implemented an SRS service, so to have my domain as the envelope sending address. Now I also want to enable DKIM-signing of these outgoing emails. Problem is: - SRS (or at least the product I am using, postsrsd) works at the "cleanup" level, so after smtpd - My DKIM-signing tool is a milter, so acts at smtpd time. So the email it sees is with the original sending domain and not my domain. How can I achieve the intended behaviour? Thank you in advance for your help Marco
