Hi, is there a problem with the server, which is running this list, or do I have an issue with my DNS-server? mail:/ # host 193.210.130.67 Host 67.130.210.193.in-addr.arpa. not found: 3(NXDOMAIN) which leads to postfix complaining: May 30 13:28:39 mail postfix/smtpd[25014]: NOQUEUE: reject_warning: RCPT from unknown[193.210.130.67]: 450 4.7.1 Client host rejected: cannot find your reverse hostname, [193.210.130.67]; from=<dovecot-bounces at dovecot.org> to=<hanns at hannsmattes.de> proto=ESMTP helo=<dovecot.org> Regards Hanns
