Forward DNS points a domain name to an IP address. Reverse DNS does the opposite: it points an IP address back to a hostname. Many receiving mail servers check that the two line up — a practice known as Forward-Confirmed Reverse DNS (FCrDNS) — before deciding whether to trust a message.
A server sending mail from an IP with no rDNS record, or one that resolves to a generic hosting-provider hostname, looks less trustworthy to spam filters than one with a PTR record matching the sending domain. Since VPS For Life includes a dedicated IPv4 address on every plan, that PTR record is entirely yours to configure.
A small DNS change with an outsized effect on inbox placement.
Set your reverse DNS to something like mail.yourdomain.com instead of a generic hosting hostname.
Forward and reverse DNS alignment is one of the checks many mail providers run before accepting a message.
Because your IPv4 address isn't shared, its PTR record reflects only your sending activity.
rDNS is one layer of authentication; combine it with SPF, DKIM and DMARC for the full picture.
Send us your hostname request and our team sets the PTR record on our end.
Configure your HELO/EHLO hostname on the server side to match the PTR record.
Custom rDNS configuration is included as part of standard support, not billed as a premium add-on.
Send your requested hostname and A record confirmation, and our team updates the PTR record promptly.
Combine a matching rDNS record with our open Port 25 policy for a properly authenticated sending setup.
Reverse DNS (rDNS) maps an IP address back to a hostname, the opposite of a standard forward DNS lookup, and is stored as a PTR record.
Many receiving mail servers check that an IP's reverse DNS resolves to a hostname consistent with the sending domain before accepting a message.
PTR records for hosting-provider IP ranges are typically set by the provider on request; contact our support team with the hostname you need.
Yes, since rDNS is set per IP address, a dedicated IPv4 address — included on every plan — is required.
No, rDNS is one authentication layer; SPF, DKIM and DMARC, plus a clean sending IP, all contribute to inbox placement.
Once you confirm the hostname and it has a matching forward A record, our team typically updates the PTR record promptly.
