Roundcube how to send email from IPV6

[feerdispzoo]

I have configure mail server. The problem is because all IPs from OVH is added on black list and my email go to spam. I received information I need to add IPV6 and send email from ipv6 to solve this issue.

I add in DirectAdmin in IP mangament IPV6, now I set for user ipv6 as main IP and ipv4 as additional IP.

Now I replace all records in cloudflare to IPV6 (I get all this records from directadmin dns mangament).

Now When I send email from rouncube do mail tester, then still is displayed ipv4. How to change to ipv6 ?

I believe mail-tester doesn’t support IPv6 (yet). You can test it with Gmail and then view the original source. IP info and SPF,DKIM,DMARC is displayed there.
