Managing Domains

This guide walks through managing domains on Overton.cloud — verifying ownership, configuring DNS, adjusting domain settings, and troubleshooting the issues that come up most often.

Domain Verification

New domains must be verified before they can be used. Add a TXT record at your DNS provider using the verification key shown in the Control Panel’s DNS section, then wait for it to propagate — typically 5–30 minutes.

  1. Get your verification key
    Open the DNS section in the Control Panel at email.adastra.ad and copy the verification key for your domain.
  2. Add a TXT record
    At your DNS provider, create a TXT record using the supplied key.
  3. Wait for propagation
    Verification usually completes within 5–30 minutes once the record is live.

DNS Configuration

Configure the following records at your DNS provider so mail routes to Overton.cloud and authenticates correctly.

MX Records

Your MX records are specific to your server and point to mxrouting.net hostnames. Always use the exact values shown for your domain in the Control Panel.

SPF Record

Add a single TXT record at your root domain:

v=spf1 include:mxroute.com -all

DKIM Record

DKIM uses a unique key per domain. Copy your domain’s DKIM value from the Control Panel and add it as a TXT record at the host shown (typically x._domainkey).

One SPF record only

A domain must have exactly one SPF record. Multiple SPF TXT records will cause authentication to fail — merge them into a single record if you use more than one sending service.

Domain Settings

From the Control Panel you can fine-tune how each domain behaves:

SettingWhat it does
Catch-all addressRoutes mail sent to any address that doesn’t have its own mailbox to a chosen account.
Domain PointersAdds domain aliases so additional domains share this domain’s accounts and settings.
Spam filteringAdjusts spam filtering options for the domain.

DNS Tester

The Control Panel includes a built-in DNS Tester that checks your MX, SPF and DKIM records and reports whether each is configured correctly. Run it after making DNS changes to confirm everything is in place.

Troubleshooting

ProblemWhat to check
Emails aren’t being deliveredVerify your MX records match the Control Panel and allow time for DNS propagation.
SPF checks failConfirm the SPF syntax is correct and that there is only one SPF record on the domain.

Use the DNS Tester first

Before opening a ticket about delivery problems, run the DNS Tester — it pinpoints which record is missing or misconfigured most of the time.
