PTR record for static IP

[#1]

I have been using a static IP address for some years and hosting my own email server equally for many years, however it is becoming more and more frequent that some email providers are treating my emails as SPAM because my reverse DNS PTR does not match my domain - can this be fixed, please?

Heya @GrahamLW,

I apologize for the delay in addressing your request. It appears that an agent submitted a request for the changes to be made in mid-December, but unfortunately, it was rejected. I have now opened a conversation on your account with the necessary information to proceed. I look forward to hearing back from you.

Hi ... the domain in question is: wenlockwich.me.uk

Thank you, Graham
