Hello WARNING , I USE FOR ISPConfig DNS MANAGEMENT, ON M 'CALLED OUT OF A PAY ZONE I leave with a second problem. Gmail can not answer me. IPV4, it works flawlessly, nickel we'll say. In IPV6, nothing works, do you have a more correct answer than mine? Thank you Mz
The reverse record is normally set on the dns server of your ISP and not in ispconfig. Contact the suport of the datacenter where you have hosted the server and ask them to set a reverse record for your ipv6 ip.
hello Till It looks ok on my side. Even when I check my reverse my IPV6, I have no errors. I add this to my SPF: After updating the DNS, I still have the same result. Yours Mz
And you have a valid aaaa-record (and ptr) for spool.domain.com? Even if you updated your spf-record, other servers will not know about the change in realtime.
This is not a validate spf-record. Read and understand #5 and checkout http://www.openspf.org/SPF_Record_Syntax
When you say Gmail cannot answer, do you mean email to Gmail is bouncing? I have seen an issue with some MTAs where they pull a IPv6 address for gmail.com. This fails if your server's IPv6 is not working properly. The email is then deferred. The email will be tried again later. When this happens, not all MTAs will switch to using IPv4. They randomly select between IPv6 and IPv4. As a result some email will go through and some will not. My solution was to disable IPv6 on the server and set the MTA to only use IPv6.
hello Yes If that answer, I tested the reverse IPV6 and it works flawlessly I did not understand your solution, can you explain better what you said? Thank you Mz
You can use transports_maps to use ipv4 with gmail: http://blog.schaal-24.de/ipv6/mails...-nur-ueber-ipv4-oderipv6-verschicken/?lang=en
