cloonan, I clicked on verify my email in the Cloudflare dashboard but I do not get any email. I noticed “notify” has only IPV4 support, while my mail server, “A [dot] MYDNS [dot] MYSITE [dot] NAME [dot] MY” has an AAAA record pointing to an IPV6 number.
I am able to receive emails from Gmail, Outlook, and even Migadu as they are all dual stack. Is it possible for Cloudflare to support IPV6 on its notify mail server? I did try to email postmaster [dot] notify [dot] Cloudflare [dot] com and the email bounced as my ISP is IPV6 only.
Cloudflare must try to be dual stack as I am on an IPV6 only network.
I have managed to debug the problem and it is because Cloudflare’s mail server notify DOT Cloudflare DOT com does not support IPV6. As my email address root AT a DOT mydns DOT mysite DOT name DOT my is IPV6 only, I had problems receiving the verification email. However, I did a simple “trick” by using improvmx to get an IPV4 mx and then I received the verification email. Then, I discontinued improvmx. Currently, this is the only way to workaround as Cloudflare does not support IPV6 on the notify server.
