Configuring MX Records for Gmail
Sign in to your hosting account, and go to the MX record maintenance page. MX records may be located in DNS Management, Mail Server Configuration, or Name Server Management. You may have to enable advanced settings to edit your MX records.
Delete all existing MX entries.
Enter the following MX records. You may not be able to enter the priority value exactly as it appears in the table below—if you can’t, make sure each record follows the indicated order. If you aren’t able to assign priorities, you should only enter aspmx.l.google.com.. Set any TTL values to 1 Hour (value=3600).
Priority Mail Server
Note: ASPMX.L.GOOGLE.COM is the top priority mail server. Don’t assign to any other servers. Learn more about mail server priority. Be sure to include trailing dot (.) at the end of any full-qualified domain names (for example, server.example.com.) if your MX records require this format.
Save your changes. Your MX records are now configured to point to Google. Keep in mind that changes to MX records may take up to 48 hours to propagate throughout the Internet.
