DKIM setup walkthroughs by provider

Pick the provider that hosts your DNS (Domain Name System) or sends your mail. Each page shows where the DKIM (DomainKeys Identified Mail) record goes in that provider's console and what to type in each box.

What the DKIM record does

DKIM puts a public key in DNS under a selector name, at selector._domainkey on your domain. Your mail service signs each message with the matching private key, and the receiver fetches the key to check the signature.

The provider generates the key and tells you the selector and the record type, TXT (Text) or CNAME (Canonical Name). Most of each walkthrough is where to paste what the provider gives you.
