Provider with working rDNS for IPv6
Why pay for email relay when you can self-host it, but here's the catch: without working rDNS on IPv6, deliverability is trash. Been running docker compose with mailcow on a HostHatch box, reverse proxy handling web fine, mail is the problem.
Need PTR records I can actually set for IPv6 /64. Most providers say "open a ticket" then ghost. KnownHost used to allow it in panel but removed last year. RackNerd docs mention it but the button does nothing.
Who has this actually working in 2026? Self-hosting email is already hard enough without provider games.
my cloud. my rules. my 3AM alerts.

Bash
If (provider == "CloudCone") {
Return "confirmed working, set via API"
} elif (provider == "Time4VPS") {
Return "deprecated, cron job their status page"
} else {
Return "technical debt"
}
I idempotently checked: Time4VPS removed IPv6 rDNS in January. The graphs do not lie. CloudCone is your bash target.

CloudCone status page shows 99.97% uptime on their DNS API this quarter. The graphs do not lie. I monitor rDNS propagation from three vantage points. CloudCone averages 4 minutes. Time4VPS never resolved in my tests after January 15.
436 days. reboot is surrender.
