How to Edit or Remove an MX Record in cPanel on Tublat

Introduction

Managing MX (Mail Exchanger) records correctly is essential for ensuring reliable email delivery. Sometimes you need to edit an existing MX record—for example to change the mail server address or priority—or remove an old or incorrect MX entry. If your domain is hosted via Tublat, you can perform both actions via cPanel’s DNS / Zone Editor interface. This guide explains step by step how to edit or delete an MX record, along with tips, best practices, and troubleshooting for smooth email configuration.

Why You May Need to Edit or Remove an MX Record

1. Switching Email Providers: When migrating from one mail service (e.g. Tublat’s built-in mail server) to a third-party provider (like Google Workspace, Microsoft 365).

2. Changing Priority: Adjusting MX priorities so that one mail server becomes primary or backup.

3. Removing Old Entries: Cleaning up redundant MX records that no longer apply.

4. Correcting Mistakes: Fixing typos in hostnames or priorities that cause email delivery failures.

5. Compliance & Security: Removing MX entries that point to deprecated or insecure servers.

Making inaccurate changes can disrupt email flow, so proceed with care and verify after each update.

Prerequisites

Before editing or deleting an MX record, ensure you have:

• Access to cPanel and the Zone Editor (or DNS management) for that domain.

• The correct mail server hostname and priority information (if editing).

• Awareness of existing MX entries to avoid conflicts.

• Patience for DNS propagation; changes may take from minutes to a few hours to fully spread globally.

Step-by-Step: How to Edit an MX Record in cPanel

1. Log in to Your Tublat cPanel
   Use your domain’s cPanel URL (e.g. yourdomain.com/cpanel) or via the Tublat dashboard.

2. Open the Zone Editor / DNS Management
   In the cPanel interface, locate Zone Editor (or DNS Zone Editor) under the Domains / DNS section.

3. Select the Domain and Click “Manage”
   Find the domain whose MX record you want to change, and click Manage or the gear icon to view DNS zone records.

4. Locate the MX Record You Wish to Edit
   In the list of DNS records, filter or scroll to find entries with record type MX.

5. Click the “Edit” Button for That MX Record
   Many cPanel setups show an Edit option next to each MX record. Click it to open editing fields. (If Edit is not visible, record types or editing may be restricted in your hosting plan.)

6. Modify the MX Record Details

   • Hostname / Name: Usually the domain or subdomain (often @ or blank for root).

   • Priority: Change the numeric priority to reflect the new order.

   • Destination / Mail Server: Update the hostname of the mail server (e.g. mail.newprovider.com).

   • Optionally adjust the TTL (Time to Live) if the interface allows.

7. Save the Edited Record
   Click Save Record, Update, or equivalent. The record will update in the DNS table.

8. Verify the Change
   Use dig, nslookup, or online MX lookup tools to check that the new MX entry is active and has correct priority.

Step-by-Step: How to Remove (Delete) an MX Record in cPanel

1. Access the Zone Editor
   Same as above: log in and go to DNS / Zone Editor → Manage domain.

2. Find the MX Record to Remove
   Scroll to the MX record you no longer need.

3. Click “Delete” or a Trash Icon Next to It
   There is usually a Delete or Remove link for the record. Click it. Some interfaces prompt for confirmation—choose Yes / Confirm.

4. Confirm & Commit the Deletion
   The record is removed from the table and no longer active in the zone.

5. Validate the Removal
   Ensure the MX record no longer appears via dig or MX lookup. Email may stop being delivered to that host, so confirm your remaining MX entries are valid.

Best Practices & Tips

• Always backup DNS zone or copy current MX entries before editing or removal.

• Minimize TTL (e.g. 300 seconds) if you expect to change MX records frequently; use higher values when stable.

• Avoid leaving a domain with no MX record—at least one valid MX entry must exist for email to work.

• If switching providers, add new MX first before deleting old ones to prevent downtime.

• After editing or deletion, wait for DNS to propagate (might take a few minutes to an hour).

• Confirm Email Routing settings in cPanel match the new MX configuration (Local, Remote, Backup).

• Use consistent, correct hostnames—always include the fully qualified domain name (FQDN) with trailing dot if needed.

• Don’t mix CNAME and MX for the same hostname.

• For domains with multiple MX entries, maintain distinct priorities to control failover logic.

Common Errors & Troubleshooting

• Edit / Delete options not visible: The hosting plan may restrict MX editing — contact Tublat support to enable DNS editing.

• Changes not propagating: Clear DNS cache locally or wait longer; some TTL settings delay updates.

• Emails bounce after removal: You might have removed the only valid MX record. Ensure remaining MX entries are correct before deleting.

• Wrong priority or destination: Mistyped hostnames or priority values will cause delivery failures.

• Reverse DNS or SPF mismatches: Ensure that reverse DNS and SPF records align with your new mail server.

• Interface caching issues: Sometimes the DNS editor UI doesn’t refresh immediately — re-load the page or click a refresh icon.

Why This Matters for Tublat Users

For Tublat users, the ability to edit or remove MX records via cPanel gives you direct control over email routing and provider changes. Correct MX configuration is vital for email reliability, deliverability, and service migrations. A small misconfiguration can lead to undelivered or lost email, so having a clear guide helps minimize risk. By following the above steps, you can maintain email service continuity, execute provider transitions cleanly, and ensure your domain’s email is always routed properly.
