rDNS is needed on this VPS mail server because most other big branded mail servers won’t accept emails from it without rDNS.
This is done only ONCE and it’s only on the account domain’s server. Also, it stays with a server rebuild but only if the previously used server name is re-used exactly, as well as the same IP address. Otherwise, you have to ask your host provider to activate rDNS again.
1. Check if Account Domain Server already has rDNS
To start, you can use the beginning of this process to check what the current rDNS entry is showing. That’s because this record is not kept on this unmanaged VPS. So, check with your host provider for testing and requesting to add rDNS. For an example, the SpeedyPage host provider has the steps to verify it and to change it.
2. SpeedyPage (VPS Host): Request rDNS on Account Domain Server
- Helpful URL: SpeedyPage “How to configure rDNS records on our VPS platform”
- SpeedyPage states: All entries must have a corresponding forward record already set at the domain’s DNS provider.
- Logon to SpeedyPage Client Area.
- In “My Dashboard”, click <Services>.
- Then, tap on this Virtual Server.
- Scroll down to the “Management Actions” section & click <Open Control Panel>.
- Take note of the displayed FQDN (hostname), e.g., server.<my account domain>
- From the top menu bar, click “Network” tab.
- Scroll down to section “IPv4 Addresses”.
- If <Reverse DNS> is showing, that means it currently does NOT have an rDNS entry and needs it.
- So, click <Reverse DNS> button.
- In the prompt, enter in the previously displayed FQDN (hostname): server.<my account domain>
- Click <Update>. Then, close this popup box.
- Then, when you bring up “Network” in the future, the <Reverse DNS> button no longer appears but the IPv4 Addresses section now has a column named “RDNS” info show up.
- Consider option to forward all emails to personal email address.
