I see, but I cannot understand what does it need me to add. I know it has to be a PTR record, but what about the hostname and the target domain(im using cloudflare)
Yes, while I was trying to figure out why I cannot receive any emails, I came across the statement that my Ip is banned from Spamhaus, even tho I havent really done anything…
As I said before, I am not really good with ubuntu or any other stuff, really, but I have heard of Ipv6, but I do bot know where to find that. Thanks for your reply.
