Updating Your MX Records

An MX record is a type of DNS record that defines where mail servers need to deliver any email that is sent to anyone on your domain. In order for your domain to be able to receive email messages at Rackspace, you must update the MX record values through your DNS host to point to Rackspace.

Contact your DNS hosting provider and have them implement the following information into your DNS zone file.

Note: If you have access to the DNS records for your domain you can make these changes yourself. 

Name/Host/Alias Time To Live (TTL) Record Type Value/Answer/Destination Preference
Blank or @ 1 hour MX mx1.emailsrvr.com 10
Blank or @ 1 hour MX mx2.emailsrvr.com 20

Note: It typically takes between 24 and 48 hours for MX records to fully update. If you run a business, we recommend updating your MX records during the slow period of your operating hours. Doing so enables the servers to fully propagate. No mail is lost while the MX records are updating.
