Step by step in DreamHost

Point your MX records

MX records tell other mail servers where to deliver your email. How MX works

Type
MX
Host
Leave this field empty
Custom MX Records
10 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
Leave this field empty
Custom MX Records
20 mx2.emailsrvr.com

In DreamHost

  1. Open the Custom MX page in the panel and click Edit to the right of your domain.
  2. In Custom MX Records, enter each record as the priority, a space, then the server (for example 1 ASPMX.GOOGLE.COM). Don't add @ or a final dot.
  3. Click Change this domain to use custom MX records now!
  4. Repeat for each MX record above.

Add the SPF record

SPF lists the services allowed to send email as you. How SPF works

Type
TXT
Host
Leave this field empty
TXT Value
v=spf1 include:emailsrvr.com ~all

In DreamHost

  1. On the DNS Settings page, click Add Record.
  2. Hover over the TXT section and click ADD.
  3. Fill in Host (leave it blank for your bare domain) and TXT Value.
  4. Click Add Record to save.

Set up DKIM

DKIM signs your mail so receivers can trust it. How DKIM works

Type
TXT
Host
See below
TXT 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 DreamHost

  1. On the DNS Settings page, click Add Record.
  2. Hover over the TXT section and click ADD.
  3. Fill in Host (leave it blank for your bare domain) and TXT Value.
  4. Click Add Record to save.

Add the DMARC record (recommended)

DMARC tells receivers what to do with mail that fakes your domain. How DMARC works

Type
TXT
Host
_dmarc
TXT 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 DreamHost

  1. On the DNS Settings page, click Add Record.
  2. Hover over the TXT section and click ADD.
  3. Fill in Host (leave it blank for your bare domain) and TXT Value.
  4. Click Add Record 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
Points to
autodiscover.emailsrvr.com

In DreamHost

  1. On the DNS Settings page, click Add Record.
  2. Hover over the CNAME section and click ADD.
  3. Fill in Host (a subdomain, never the root) and Points to.
  4. Click Add Record 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 DreamHost’s words.

We only read public DNS records. Nothing is stored.

Leaving other MX records

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

Rackspace Email on DreamHost: questions

Where do I add Rackspace Email DNS records in DreamHost?

In the DreamHost panel, go to Manage Websites. Select the three-dot button under your domain, then DNS Settings. Add each record there, one at a time.

What goes in the Host field at DreamHost?

Leave it empty for records on your bare domain, such as MX and SPF. For the others, enter only the part before your domain, for example _dmarc. DreamHost adds your domain automatically.

Do I need to delete my existing MX records at DreamHost?

Yes. Sending servers pick an MX record by its priority (lowest number first) and fall back to the others, so a leftover MX record can receive some or all of your mail. Keep only the Rackspace Email MX records and delete the rest. Once custom MX records are added, email is no longer delivered to DreamHost and the domain's DreamHost mailboxes are deactivated.

Where do I get my Rackspace Email DKIM record?

Use the value shown in the table on this page.
