Big names labeling my email as spam

[type-00]

I have a similar problem but here's the thing that happened with me I had dkim on the server and working and my score with a mail tester was 97 because all my name servers were the domain.com ones so I try ed to add the one on my sentora server as one and got it to work but mail started going to spam so I try ed fixing that in the dns of my server and now my ip was black listed in two places but now only one so I have to try and fix that but I made everything the same as it was before getting blacklisted so until I get off the black list mail will keep going to spam
