A user at a Starbucks is trying to send mail and getting an error on sending. This is what I see in the logs:
Jun 1 15:09:08 mail submit-tls/smtpd[88479]: warning: hostname 50-253-97-91-static.hfc.comcastbusiness.net does not resolve to address 50.253.97.91: hostname nor servname provided, or not known Jun 1 15:09:08 mail submit-tls/smtpd[88479]: connect from unknown[50.253.97.91] Jun 1 15:09:08 mail submit-tls/smtpd[88479]: SSL_accept error from unknown[50.253.97.91]: lost connection Jun 1 15:09:08 mail submit-tls/smtpd[88479]: lost connection after STARTTLS from unknown[50.253.97.91] Jun 1 15:09:08 mail submit-tls/smtpd[88479]: disconnect from unknown[50.253.97.91] and this is what I have for submission: submission inet n - n - - smtpd -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_sasl_type=dovecot -o smtpd_sasl_security_options=noanonymous -o smtpd_sasl_path=private/auth -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_data_restrictions= -o smtpd_relay_restrictions=permit_sasl_authenticated,reject_unauth_destination,reject -o smtpd_helo_restrictions= -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject_unauth_destination,reject -o syslog_name=submit-tls Is there anything that I have set that is causing this to fail? (My own connection is also a Comacastbusiness.net IP, and I connect without issues). -- "You never really understand a person until you see things from his point of view, until you climb inside of his skin and walk around in it."
