MX Settings for Rackspace Mail

You are reading this article because you currently have your email hosted with another company and wish to migrate over to our Rackspace Mail solution or you have your email with us and your DNS is hosted somewhere else.

You will need to adjust your DNS as follows and add the MX records, SPF and CNAME:

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

This is a very simple change to the dns record for your domain. To be able to do this you need to have access to your dns records so if you do not know how to do this, please ask your technical representative or domain provider who should be able to easily change this for you.

We also recommend that you apply SPF records for the domain. More information about SPF records for Rackspace mail can be found here: 

IMPORTANT NOTE: if you have control panel like Cpanel or similar, then you will need to make sure that the web site server records are treating your email accounts as "EXTERNAL EMAIL". If you dont you might find that any web site generated emails will try to be delivered locally to the web server and never delivered to your email account. See this article about external mail and web forms:
