On: Self-hosting email like it's 1984

How big a deal is reverse DNS for this and anything else in 2025? I've not created any PTR records for anything for about 20 years now...

No deal, even possible for ipv6 easily with eg Hetzner, Vultr

Thank you. I'm hosting all my boxes with Hetzner. The option is right there and I never knew. Might as well add it.

Ironically, self-hosted mail servers are more likely to bounce incoming mail from someone without a proper PTR than the big mail service providers.
