Type
MX
Host
Leave this field empty
Priority
10
Answer
mx01.mail.icloud.com
  • Apple's page writes these with a trailing period (mx01.mail.icloud.com.). Use whichever form your DNS host expects.

  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:icloud.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
CNAME
Host
sig1._domainkey
Answer
sig1.dkim.yourdomain.com.at.icloudmailadmin.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.

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
  • 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 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.

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.
