Step by step in DreamHost

Verify your domain

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

Type
TXT
Host
Leave this field empty
TXT Value
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 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.

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
Custom MX Records
10 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
Host
Leave this field empty
Custom MX Records
10 mx02.mail.icloud.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 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
TXT Value
v=spf1 include:icloud.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 publishes a public key so receivers can confirm your messages really came from you and were not changed on the way.

Type
CNAME
Host
sig1._domainkey
Points to
sig1.dkim.yourdomain.com.at.icloudmailadmin.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.

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
TXT Value
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 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.

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.

Common mistakes with iCloud+ Custom Email Domain on DreamHost

iCloud+ Custom Email Domain on DreamHost: questions

Where do I add iCloud+ Custom Email Domain 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 sig1._domainkey. DreamHost adds your domain automatically.

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

Yes. Mail servers deliver to every MX record you publish, so keep only the iCloud+ Custom Email Domain 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 iCloud+ Custom Email Domain DKIM record?

iCloud+ Custom Email Domain DKIM records are CNAME records whose value includes your domain, for example sig1.dkim.yourdomain.com.at.icloudmailadmin.com. Copy the exact values for your domain from the table on this page.
