Hi,
After reading the http://www.postfix.org/BACKSCATTER_README.html, I have included the following to /etc/postfix/header_checks: /^[> ]*Message-ID:.*@(mydomain\.com)/ HOLD forged domain name in Message-ID: header: $1 Glad that I put HOLD rather than REJECT as IOS devices are producing this format Message-Id: <[email protected]> Is there a way to change the Message-Id for authenticated users and how can I do it? Thanks
