Configure Exim for IPv6 priority

I believe at present cPanel has IPv4 configured to take priority over IPv6 for sending mail through Exim, Is it possible yet to use IPv6 only yet? We have a server in Europe in an OVH data center and UCE Protect has placed their European ASN on a block list so our London server is having problems sending mail to servers who use UCE Protect, however OVH says UCE Protect cannot/does not block IPv6 so that's our way out of the problem.
We did ask OVH to get UCE Protect to remove their european ASN block but they say "Paying to be removed on a blacklist is extortion and against all industry standards. "

You should not need anything special - it's a public page that isn't linked to an internal case, so no special access is required. Could you try a different browser or clearing your cache?
Yes, I've tried both different browsers and private windows. As kernow mentioned, it does take you to cpanel ID page and requires authentication.

I've even tried searching the title in bing and google, and it finds the exact same page and it forces me to cpanel ID as well.

Since I'm having the exact same problem as the OP (OVH ASN is being blacklisted by UCEPROTECT's Level 3 blacklist), I would really like to prioritize ipv6 on exim.
