Admin tip: set rDNS / PTR on a crypto VPS

Mail and some APIs want a PTR that matches the HELO. Ticket the hostname. You run Postfix.

Short answer

Set a hostname, open a ticket with the PTR you want, then match SMTP or APIs to that name. We do not run your mailer.

PTR you can edit. Mail and some APIs want matching rDNS. Open a ticket with the name.

Why PTR shows up in tickets

Receiving MTAs and a few payment APIs check reverse DNS. Postfix documentation will not save you if the PTR is a generic allocator name. This is the usual first ticket after someone buys a mail VPS with crypto.

What to send

  1. The IPv4 (and IPv6 if you use it).
  2. The FQDN you already pointed A/AAAA at.
  3. Invoice code if the panel is new.

Then harden OpenSSH manual and keep port 25 for mail you actually operate. We do not run the MTA.

IPv6 PTR?

Yes, if you published the AAAA. Say so in the ticket.

How fast?

Same support queue as any other ticket. Not a self-serve DNS panel.
