Q: Message does not meet IPv6 sending guidelines regarding PTR 550-5.7.1 records and authentication
I use OS X Server (El Capitan) as my personal email server. Everything is configured correctly. Mail works great for every domain except google gmail. This has been going on for 2-3 years...when ever I send email to Gmail users I get "undelivered mail returned to sender" which explains "this message does not meet IPv6 sending guidelines regarding PTR 550-5.7.1 records and authentication".
How can this be fixed?
Mac mini Server (Mid 2010), OS X Server, null

You only need to create a spf or txt record in your public dns( at your register) as this will be queried by your counterpart mail exchange.
On how to achieve this at GoDaDy - I am not sure (not a customer of them)
but i presume go to your where your product are (domain name) and see if there is an option to maintain dns for this domain
add a new record (txt or spf) pref a txt record as the spf record is deprecated.
this is my txt record ”v=spf1 mx a ip4:83.163.175.235/32 ip6:2001:982:b301:1:6a5b:35ff:fec6:41b4 a:frodo.cornerstoneshop.nl a:pepijn.xs4all.nl -all"
if you do a NSlookup -query=txt domain.com you’ll get the txt/spf of that domain
there is a good site to check if your txt/spf records are ok — http://www.kitterman.com/spf/validate.html
good luck
