DKIM (DomainKeys Identified Mail)

DKIM (DomainKeys Identified Mail) is a mechanism that allows senders to associate a domain name with an e-mail message. In technical terms, DKIM is a technique to authorize a domain to associate its name to an email message through cryptographic authentication.

DKIM has the following look in your account:

Host	Type	Points to:	TTL
_domainkey.yourdomain.com	TXT	DKIM-specific-text	3600

In ClouDNS, you can use it by creating a TXT record.

To create DKIM, go to your DNS Zone Control Panel, click on "Add new record" and type, as follow:

Type: TXT
Host: (something.)_domainkey
Points to: DKIM-specific-text

Notes:

Host: The host is given you by the domain key generator (it may be something._domainkey or only _domainkey)

Points to: DKIM-specific-text (this string here is also given by the DKIM generator)
