I’m running a milter that may perform rejection (SMFIS_REJECT) at the milter HELO stage. This condition appears in the system log as follows:
Jan 04 13:50:07 mail postfix/smtpd[149922]: connect from unknown[156.0.64.217] Jan 04 13:50:07 mail spf-milter[147333]: mail.mydomain.org (helo): fail Jan 04 13:50:07 mail spf-milter[147333]: rejected message from sender "mail.mydomain.org" Jan 04 13:50:07 mail postfix/smtpd[149922]: NOQUEUE: milter-reject: HELO from unknown[156.0.64.217]: 550 5.7.23 SPF validation failed; proto=SMTP helo=<mail.mydomain.org> Jan 04 13:50:07 mail postfix/smtpd[149922]: NOQUEUE: milter-reject: MAIL from unknown[156.0.64.217]: 550 5.7.23 SPF validation failed; from=<> proto=SMTP helo=<mail.mydomain.org> Jan 04 13:50:08 mail postfix/smtpd[149922]: lost connection after MAIL from unknown[156.0.64.217] Jan 04 13:50:08 mail postfix/smtpd[149922]: disconnect from unknown[156.0.64.217] helo=1 mail=0/1 commands=1/2 • Why does Postfix log ‘milter-reject’ twice? • Why does it also log milter rejection for the MAIL stage, when the client was rejected already at the HELO stage? Thank you. -- David
