Types of DNS entries

The following DNS entries are required to use email services at Rackspace properly:

  • MX records tell other email providers where to send email. Your MX records should point to Rackspace.

  • SPF records reduce unwanted SPAM and spoofing from your domain and ensure that outgoing emails are delivered.

  • Autodiscover records allow for full functionality of calendar features (free/busy information) and easier email client setups. 

Configure DNS to send and receive email

Use the following steps to ensure your domain properly routes incoming and outgoing email.

  1. Set the DNS entries to the values shown in the following table. Ensure that no other MX record entries exist, or you will experience complications with your email. 
Type Hostname Destination Priority TTL
MX @ or left blank 10 3600 seconds or lowest allowed
MX @ or left blank 20 3600 seconds or lowest allowed
TXT @ or left blank v=spf1 ~all NA 3600 seconds or lowest allowed
CNAME autodiscover NA 3600 seconds or lowest allowed
**Note:** Your new settings take 24 to 48 hours to propagate to the world. For more information on propagation, see [DNS propagation](/support/how-to/dns-record-definitions#dns-propagation).
  1. Save your changes.

You have successfully set up your DNS for your domain.
