ipv6 in New Feature Request Posted August 8, 2012 Hi, halloween, ...Uh-oh, IPv6 is reported to be fixed (Scheduled Service Outage)! Please post a Tracking URL. Yes, I had a report with IPv6 that worked - good to see. This one worked: Received: from oproxy11-pub.bluehost.com (unknown [2605:dc00:100:2::a3]) by www.xxx.yyy.zzz with SMTP; This one did not: Received: from oproxy11-pub.bluehost.com (unknown [iPv6:2605:dc00:100:2::a3]) by www.xxx.yyy.zzz with SMTP; This is more a problem with the mailer adding the IPv6: bogus part I believe, but it's worth mentioning in case others hit this issue. I don't know what mailers add that tag, but it may be worth adding something to be defensive in the spamcop processor - perhaps with warnings in the report summary.
