Hello, since probably beginning of December, I have severe problems receiving emails from the torque and maui mailing lists. Our mail server refuses to accept any emails from supercluster.org because of a missing PTR Resource Record in DNS. Because of the missing PTR, reverse DNS lookups do not work for supercluster.org's IP.
Jan 16 11:01:58 bolte82 postfix-rz-in/smtpd[26316]: NOQUEUE: reject: RCPT from unknown[68.178.11.139]: 550 5.7.1 Client host rejected: cannot find your reverse hostname, [68.178.11.139]; from=<[email protected]> to=<thomas.zeiser at rrze.uni-erlangen.de> proto=SMTP helo=<http.supercluster.org> $ host supercluster.org supercluster.org has address 68.178.11.139 supercluster.org mail is handled by 0 supercluster.org. supercluster.org mail is handled by 10 clusterresources.com. $ nslookup 68.178.11.139 ** server can't find 139.11.178.68.in-addr.arpa.: NXDOMAIN Google's Public DNS servers tells exactly the same: $ nslookup 68.178.11.139 - 8.8.8.8 Server: 8.8.8.8 Address: 8.8.8.8#53 ** server can't find 139.11.178.68.in-addr.arpa.: NXDOMAIN Thus, it does not seem to be a local issue at our side but something Adaptive Computing (or who ever owns supercluster.org) has to fix. Kind regards, Thomas Zeiser _______________________________________________ mauiusers mailing list [email protected] http://www.supercluster.org/mailman/listinfo/mauiusers
