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.
- Get your verification key
Open the DNS section in the Control Panel atemail.adastra.adand copy the verification key for your domain. - Add a TXT record
At your DNS provider, create aTXTrecord using the supplied key. - 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:
| Setting | What it does |
|---|---|
| Catch-all address | Routes mail sent to any address that doesn’t have its own mailbox to a chosen account. |
| Domain Pointers | Adds domain aliases so additional domains share this domain’s accounts and settings. |
| Spam filtering | Adjusts 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
| Problem | What to check |
|---|---|
| Emails aren’t being delivered | Verify your MX records match the Control Panel and allow time for DNS propagation. |
| SPF checks fail | Confirm 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.
