Can I set reverse DNS (PTR) records myself?
Short answer
Yes, for both IPv4 and IPv6, directly from the control panel, and changes propagate within minutes. Reverse DNS is essential for mail: most large receivers reject messages from an address whose PTR record does not resolve back to the sending hostname.
Set the PTR to the same hostname the server announces in its SMTP banner, and make sure that hostname has a forward A or AAAA record pointing back to the same address. That round trip — forward-confirmed reverse DNS — is what receivers actually check.
If you run several services on one address, set the PTR to the mail hostname. It is the only service that cares.
