iCloud+ Custom Email Domain records

SPF Includeinclude:icloud.com
SPF Record (on Its Own)v=spf1 include:icloud.com ~all
With Another Providerv=spf1 include:icloud.com include:other.example ~all
DKIM Selectorssig1 (CNAME)
Starter DMARC (_dmarc)v=DMARC1; p=none; rua=mailto:[email protected]

Add it to the TXT record on your domain's root.

DKIM: A CNAME record at sig1._domainkey pointing at the value Apple shows when you add the domain.

A domain can have only one SPF record. If you already send through another service, add the include to your existing record rather than creating a second one, and keep the total under 10 DNS lookups.

Once SPF and DKIM pass, add a DMARC record at _dmarc with p=none and a reporting address, read the reports for a couple of weeks, then move to quarantine and reject.
