[dpdk-dev] Any chance someone could fix the SPF records for this mailing list?

[Alexander Duyck]

I have noticed a number of emails from this list are going to spam.  It looks like it might be gmail filtering based on the fact that most of the list has a valid SPF based on an IPv4 address that reports out like below:
Received: from dpdk.org (dpdk.org. [92.243.14.124])
         by mx.google.com with ESMTP id eq6si3307415wib.54.2015.06.03.11.21.20;
         Wed, 03 Jun 2015 11:21:23 -0700 (PDT)
Received-SPF: pass (google.com: best guess record for domain of dev-bounces@dpdk.org designates 92.243.14.124 as permitted sender) client-ip=92.243.14.124;
Authentication-Results: mx.google.com;
        spf=pass (google.com: best guess record for domain of dev-bounces@dpdk.org designates 92.243.14.124 as permitted sender) smtp.mail=dev-bounces@dpdk.org

However the ones that are going straight into my spam folder list an IPv6 address that is rated neutral by the SPF:
Received: from dpdk.org ([2001:4b98:dc0:41:216:3eff:fe72:dd13])
         by mx.google.com with ESMTP id cy1si1185671wib.89.2015.06.03.04.00.32;
         Wed, 03 Jun 2015 04:00:37 -0700 (PDT)
Received-SPF: neutral (google.com: 2001:4b98:dc0:41:216:3eff:fe72:dd13 is neither permitted nor denied by best guess record for domain of dev-bounces@dpdk.org) client-ip=2001:4b98:dc0:41:216:3eff:fe72:dd13;
Authentication-Results: mx.google.com;
        spf=neutral (google.com: 2001:4b98:dc0:41:216:3eff:fe72:dd13 is neither permitted nor denied by best guess record for domain of dev-bounces@dpdk.org) smtp.mail=dev-bounces@dpdk.org

I was just wondering if it would be possible to get the IPv6 address added as a permitted sender for the domain to help reduce the amount of messages that are likely being flagged as spam for myself and likely others.

Thanks.

Hello,

I can confirm your claims. When I enabled IPv6 on my mail server Google began 
dropping or severely graylisting 100% of the mail until the IPv6 subnet was 
added to the SPF record. This needs to get fixed or the IPv6 outbound SMTP has 
to be disabled or Google users will lose tons of mails from the list.

Matthew.

There is a specific section regarding IPv6.

Thanks for the information.
Indeed the ip6: field of the SPF was not filled. It should be fixed now.

By the way, it is possible to avoid spam classification in gmail with a
filter to:(dev@dpdk.org).
