Step by step in Namecheap

Point your MX records

MX records tell every other mail server where to deliver email for your domain. They must point to your provider and nowhere else.

Type
MX
Host
@
Priority
10
Value
mx1.emailsrvr.com
  • Rackspace warns that no other MX records should exist, or you'll have problems with your email.
  • Use 3600 seconds or the lowest TTL your host allows.
Type
MX
Host
@
Priority
20
Value
mx2.emailsrvr.com

In Namecheap

  1. In the Mail Settings section, choose Custom MX from the drop-down list. You may need to scroll the list to find it.
  2. Select Add New Record.
  3. Enter @ as the Host, the mail server as the Value, and the Priority in the box to the right of the Value.
  4. Select the check mark to save the record.
  5. Delete every other MX record with its trash icon, then confirm with Yes.
  6. Repeat for each MX record above.

Add the SPF record

SPF is a TXT record that lists the services allowed to send email from your domain, so receivers can spot forgeries.

Type
TXT
Host
@
Value
v=spf1 include:emailsrvr.com ~all

In Namecheap

  1. In the Host Records section, select Add New Record.
  2. In the Type drop-down, choose TXT Record.
  3. Fill in Host and Value, and pick a TTL.
  4. Select the check mark, or Save All Changes, to save.

Set up DKIM

DKIM publishes a public key so receivers can confirm your messages really came from you and were not changed on the way.

Type
TXT
Host
See below
Value
Copy it from Rackspace Cloud Office Control Panel (see below)

Where to find your value

In the Cloud Office Control Panel, go to Domains → Sender Authentication (DKIM), select your domain and click Enable DKIM for it.

We haven’t been able to confirm this value from Rackspace Email's public docs yet, so we don’t show one.

  • After adding the TXT record, click Verify TXT Record in the control panel.
  • Allow 24 to 48 hours for the record to propagate.

In Namecheap

  1. In the Host Records section, select Add New Record.
  2. In the Type drop-down, choose TXT Record.
  3. Fill in Host and Value, and pick a TTL.
  4. Select the check mark, or Save All Changes, to save.

Add the DMARC record (recommended)

DMARC tells receivers what to do with mail that fails SPF and DKIM, and where to send reports about it.

Type
TXT
Host
_dmarc
Value
v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com
  • Rackspace's setup page doesn't list a DMARC value. This is the standard starting record; replace the report address with one you read.

In Namecheap

  1. In the Host Records section, select Add New Record.
  2. In the Type drop-down, choose TXT Record.
  3. Fill in Host and Value, and pick a TTL.
  4. Select the check mark, or Save All Changes, to save.

Add the Autodiscover record (recommended)

Autodiscover lets Outlook and other mail apps find your account settings without manual setup.

Type
CNAME
Host
autodiscover
Value
autodiscover.emailsrvr.com

In Namecheap

  1. In the Host Records section, select Add New Record.
  2. In the Type drop-down, choose CNAME Record.
  3. Fill in Host and Value, and pick a TTL.
  4. Select the check mark to save.

Check your setup

Once the records are saved, run a live check. We look up your domain in public DNS and tell you what is right, missing or wrong, with the fix in Namecheap’s words.

We only read public DNS records. Nothing is stored.

Common mistakes with Rackspace Email on Namecheap

Leaving other MX records

Rackspace says no other MX record entries should exist alongside mx1 and mx2.emailsrvr.com.

Namecheap: Switch Mail Settings to Custom MX first

MX records for an outside email provider go in the Mail Settings section, and only after you choose Custom MX. The other options (Email Forwarding, Private Email, No Email Service) manage MX records for you.

Namecheap: No CNAME on the bare domain

A CNAME record on the bare domain (yourdomain.com) overrides every other record for that name and breaks email.
