Hello,
I'm having an issue adding a domain to the mail server. I get the error "A record parsing failed" now I suspect that I maybe have the syntax wrong or I've potentially setup DNS/hosts file incorrectly.
I've been using this format
When I look at the logs there is nothing that indicates why it failed though there are some suspicious logs:-
