IPV6 Sending Requirements

Hi
Is IPV6 configuration still only available for Business Customers?
I could only find answers from long ago (2016) and I really need to address the following error message.

Our system has detected that 550-5.7.1 this message does not meet IPv6 sending guidelines regarding PTR 550-5.7.1 records and authentication. Please review 550-5.7.1

There ain't no such thing as a free lunch.

Was this helpful?

  • Yes it was, thank you
  • No, I still need help

Is that in relation to a Telstra Mail account, or email hosted in a different system?

Never be afraid to back yourself when trying new things, just always make sure you have 3 escape routes if things go wrong.

It's my own mailserver connected to my Telstra NBN

You would need to update your PTR record to include the IPv6 address of the machine that you are trying to send from. Either that or disable the iPv6 protocol in your mail server.

Thanks
I'll give it fly with the IPV6 PTR and see how it goes, no use going to IPV4 only as more and more domains are now asking for IPV6 verification and it is fast becoming the standard
