Hi, how can I tell why the following mail has been rejected:
Jul 14 08:48:58 zarafa-xen postfix/smtpd[26113]: NOQUEUE: reject: RCPT from ns.gbc.net[212.97.96.201]: 554 5.7.1 <ns.gbc.net[212.97.96.201]>: Client host rejected: Access denied; from=<joerg.hal...@flaig-hommel.de> to=<m.b...@otec.de> proto=ESMTP helo=<mail.gbc.net> "client host rejected" would require for the host to be in a "check_client_access" table, right? I can't find the IP nor the hostname in the corresponding Hash-Table. Any idea why the mail was blocked anyway? What can I do to troubleshoot such cases in the future? Can I increase the log level for mail rejections like these without turning on the verbose logging mode in general? Thanks in advance! Regards, Joern
