Step by step in Cloudflare

Verify your domain

Your email provider needs proof that you control this domain before it accepts email for it.

Type
TXT
Name
@
Content
Copy it from iCloud+ Custom Email Domain (see below)

Where to find your value

Go to icloud.com/icloudplus, select Custom Email Domain, then Add a domain you own. In step 3, select View to see your personal TXT record.

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.

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
mx01.mail.icloud.com
  • Apple's page writes these with a trailing period (mx01.mail.icloud.com.). Use whichever form your DNS host expects.
Type
MX
Name
@
Priority
10
Mail server
mx02.mail.icloud.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:icloud.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
CNAME
Name
sig1._domainkey
Target
sig1.dkim.yourdomain.com.at.icloudmailadmin.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.

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
  • Apple's setup page doesn't list a DMARC record. This is the standard starting record (p=none asks receivers for no action); 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.

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 iCloud+ Custom Email Domain on Cloudflare

Leaving example.com in the DKIM target

Apple's example target is sig1.dkim.example.com.at.icloudmailadmin.com. Replace example.com with your own domain.

Cloudflare: Keep email CNAMEs on DNS only

Set Proxy status to DNS only (grey cloud) for DKIM and verification CNAME records. Cloudflare says records used for email or domain verification should not be proxied, and may block proxying DKIM CNAMEs.

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.
