Step by step in Cloudflare

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
Name
@
Priority
10
Mail server
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
Name
@
Priority
20
Mail server
mx2.emailsrvr.com

In Cloudflare

  1. On the DNS Records page, select Add record.
  2. Choose MX as the Type.
  3. Fill in Name, Mail server and Priority.
  4. Select Save.
  5. Delete any other MX records: select Edit on each one, then Delete, and confirm.
  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
Name
@
Content
v=spf1 include:emailsrvr.com ~all

In Cloudflare

  1. On the DNS Records page, select Add record.
  2. Choose TXT as the Type.
  3. Fill in Name and Content.
  4. Select 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
Name
See below
Content
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 Cloudflare

  1. On the DNS Records page, select Add record.
  2. Choose TXT as the Type.
  3. Fill in Name and Content.
  4. Select 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
Name
_dmarc
Content
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 Cloudflare

  1. On the DNS Records page, select Add record.
  2. Choose TXT as the Type.
  3. Fill in Name and Content.
  4. Select Save.

Add the Autodiscover record (recommended)

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

Type
CNAME
Name
autodiscover
Target
autodiscover.emailsrvr.com

In Cloudflare

  1. On the DNS Records page, select Add record.
  2. Choose CNAME as the Type.
  3. Fill in Name and Target.
  4. Set Proxy status to DNS only (grey cloud).
  5. Select 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 Cloudflare’s words.

We only read public DNS records. Nothing is stored.

Common mistakes with Rackspace Email on Cloudflare

Leaving other MX records

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

Cloudflare: Turn off Cloudflare Email Routing first

If Email Routing is on, Cloudflare has added locked MX records (route1, route2 and route3.mx.cloudflare.net) and an SPF record with include:_spf.mx.cloudflare.net. Unlock them or disable Email Routing (Compute > Email Service > Email Routing > your domain > Settings) before switching to another provider. Email Routing can't be used with an outside mail server.
