travislehmantech I just set up Mailcow yesterday. My domain registrar is Namecheap but Cloudflare is handling all DNS. I can get all required DNS records except for the ipv6 PTR record. I have it added on Cloudflare but current state in Mailcow DNS shows 2.
pkernstock The PTR records at your DNS provider (like Cloudflare) does not matter. PTR/rDNS needs to be set at your server provider/whoever owns the IP address space.
travislehmantech pkernstock Thanks! I did have my provider (racknerd) set PTR for ipv4, so I’ll see if I can get them to set ipv6 as well.
