Hi all, I have the following config > smtpd_client_restrictions = > reject_unknown_client_hostname > smtpd_helo_required = yes > smtpd_helo_restrictions = > reject_invalid_helo_hostname, > reject_non_fqdn_helo_hostname, > reject_unknown_helo_hostname > smtpd_sender_restrictions = > reject_non_fqdn_sender, > reject_unknown_sender_domain
but still get warnings like this > postfix/smtpd[24986]: warning: hostname server17-ams1.internet-census.org > does not resolve to address 107.6.163.34: Name or service not known > postfix/smtpd[24986]: connect from unknown[107.6.163.34] > postfix/smtpd[24986]: NOQUEUE: reject: CONNECT from unknown[107.6.163.34]: > 450 4.7.25 Client host rejected: cannot find your hostname, [107.6.163.34]; > proto=SMTP > postfix/smtpd[24986]: disconnect from unknown[107.6.163.34] ehlo=0/1 > quit=1 commands=1/2 My understanding is that there should be no warning because the issue is explicitly checked by the "reject_unknown_client_hostname" directive. Am I missing something? Is it possible to eliminate this warning?
