Reverse DNS shows my email address

[#1]

The info is found in the Help Assistant, under Tech Support >> Domains and DNS >> Change my reverse DNS

Thanks, I've updated my ticket - you might want to have a chat with the first respondent (Who suggested I needed to register a domain ...)
Also - I had tried "Search Help Assistant" for "reverse" - but it came back with no results

I had the same problem when I looked the other day.
I'll have a word with our Content Team.
