Hello, I have setting in master.cf:
submission inet n - y - - smtpd -o syslog_name=postfix/submission -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_tls_security_level=encrypt -o smtpd_reject_unlisted_recipient=no -o cleanup_service_name=subcleanup subcleanup unix n - - - 0 cleanup -o header_checks=regexp:/etc/postfix/submission_header_checks However i can't get it working. I am sending email from MS Outlook and would like to hide the sender IP address by replacing Received header. In mail log i see this: Apr 9 17:29:34 hostname postfix/submission/smtpd[1904046]: warning: hostname client.isp.com does not resolve to address 12.34.56.78: Name or service not known Apr 9 17:29:34 hostname postfix/submission/smtpd[1904046]: connect from unknown[12.34.56.78] Apr 9 17:29:35 hostname postfix/submission/smtpd[1904046]: NOQUEUE: filter: RCPT from unknown[12.34.56.78]: <u...@host.com>: Sender address triggers FILTER smtp-amavis:[127.0.0.1]:10026; from=<u...@host.com> to=<us...@host.com> proto=ESMTP helo=<DESKTOPVEEC53B> Apr 9 17:29:35 hostname postfix/submission/smtpd[1904046]: 41D0DB80C76: client=unknown[12.34.56.78], sasl_method=LOGIN, sasl_username=u...@host.com Apr 9 17:29:35 hostname postfix/cleanup[1904050]: 41D0DB80C76: message-id=013f01d72d55$256c8ce0$7045a6a0$@host.com <mailto:013f01d72d55$256c8ce0$7045a6a0$@host.com> Submission does not forward to subcleanup but to cleanup. What is the reason ?
