Hi Dan, Hope the rest of the world is treating you decently! There are a lot of bits and bobs that one has to get right for mail to flow, amongst which: - IP -> PTR lookup -> that hostname lookup, and match to IP again (https://en.wikipedia.org/wiki/Forward-confirmed_reverse_DNS) - SPF - DKIM - DMARC - ARC (for mailinglists)
Seriously spend zero time on ARC. It doesn't work as advertised and is basically snake oil.
