Step by step in Porkbun

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
Leave this field empty
Priority
10
Answer
mx1.emailsrvr.com
  • Rackspace warns that no other MX records should exist, or you'll have problems with your email.

  3. Click Add.
  4. 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
Leave this field empty
Answer
v=spf1 include:emailsrvr.com ~all

In Porkbun

  1. Choose TXT as the Type.
  2. Leave Host blank for your bare domain (or enter the subdomain name), and paste the value in Answer.
  3. Click Add.

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
Answer
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 Porkbun

  1. Choose TXT as the Type.
  2. Leave Host blank for your bare domain (or enter the subdomain name), and paste the value in Answer.
  3. Click Add.

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
Answer
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 Porkbun

  1. Choose TXT as the Type.
  2. Leave Host blank for your bare domain (or enter the subdomain name), and paste the value in Answer.
  3. Click Add.

Add the Autodiscover record (recommended)

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

Type
CNAME
Host
autodiscover
Answer
autodiscover.emailsrvr.com

In Porkbun

  1. Choose CNAME as the Type.
  2. Enter the Host (it can't be empty) and the target in Answer.
  3. Click Add.

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 Porkbun’s words.

We only read public DNS records. Nothing is stored.
