I tried to send a message to a @comcast.net customer from my Linode VPS (with IPv6 enabled) and got the following reject:
... while talking to mx2.comcast.net.: <<< 554 resimta-ch2-17v.sys.comcast.net comcast 2600:3c03::f03c:91ff:fe96:5e2 found on one or more DNSBLs, see http://postmaster.comcast.net/smtp-error-codes.php#BL000001 The URL says that it is listed by Spamhaus Zen. AFAIK they aren't listing IPv6 (their lookup form doesn't accept IPv6 addresses at least). Is Comcast just misapplying DNSBLs to IPv6 addresses? Any Comcast admins around that could help? The above address has matching reverse and forward DNS, and I haven't had delivery issues to anybody else. Double-checked the server, and I don't see any sign of spam or anything. -- Chris Adams <c...@cmadams.net> _______________________________________________ mailop mailing list mailop@mailop.org http://chilli.nosignal.org/mailman/listinfo/mailop
