Is this something that anyone can give me pointers on setting up? I have had DNSSEC running on my VPS in the past but recently dropped it as it was proving a pain to rollover the keys. I’d like to support it now via my mail server but i’m not sure how it’d work.
I could be wrong, but I think using an external DNS defeats some of cool features/security of mailinabox.
I would recommend sticking with the way mailinabox makes its own DNS servers.
It’s brilliant the way it is, in my opinion.
That being said, if you really must, hopefully this will help you in the right direction
