Managing MX entries in WHM

What are MX Entries?

MX entries are DNS records that specify the mail servers responsible for receiving email on behalf of a domain. These records include the server’s priority and the domain name of the mail server. The priority determines the order in which mail servers are used.

Accessing MX Entry Management in WHM

To manage MX entries in WHM, follow these steps:

1. Log in to WHM: Access your WHM account by entering your username and password.
2. Navigate to DNS Functions:
   • On the left-hand sidebar, scroll down to the DNS Functions section.
   • Click on Edit MX Entry.

Editing MX Entries

Once you are in the Edit MX Entry section, follow these steps to manage the MX entries for a domain:

1. Select a Domain:
   • A list of domains will be displayed. Select the domain for which you want to edit MX entries.
   • Click on the Edit button next to the chosen domain.
2. Configure MX Entries:
   • You will see the current MX entries for the selected domain.

     • Local Mail Exchanger: Select this if the mail server is hosted on the same server.

If you have a secondary mail server for redundancy, you might add:

• Priority: 20
• Mail Server: backupmail.example.com

Testing MX Entries

After configuring MX entries, it’s essential to test them to ensure they are functioning correctly. You can use online tools like MXToolbox to verify the MX records and check for any issues.

Troubleshooting MX Entries

If you encounter issues with email delivery, consider the following troubleshooting steps:

1. Check DNS Propagation:
   • DNS changes, including MX entries, can take up to 48 hours to propagate. Use tools like WhatsMyDNS to check the propagation status.
2. Verify MX Entry Syntax:
   • Ensure there are no typos in the mail server domain names.
   • Check that the priority values are correctly configured.
3. Review Email Routing Settings:
