DomainKeys Identified Mail, or DKIM, is a system for confirming the legitimacy of an email using an e-signature. When DomainKeys Identified Mail is activated for a certain domain, a public cryptographic key is published to the global DNS system and a private one is stored on the mail server. When a new email is sent, a signature is generated using the private key and when the email is received, the signature is authenticated by the receiving server using the public key. Thus, the receiver can easily distinguish if the message is genuine or if the sender’s address has been spoofed. A discrepancy will appear if the content of the email has been changed in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered messages are identical and that nothing has been attached or removed. This authentication system will enhance your email security, as you can validate the legitimacy of the important emails that you receive and your partners can do likewise with the email messages that you send them. Based on the given email provider’s adopted policy, an email that fails to pass the test may be deleted or may enter the receiver’s mailbox with a warning flag.

DomainKeys Identified Mail in Cloud Web Hosting

The DomainKeys Identified Mail functionality is activated by default for all domain names that are hosted in a cloud web hosting account on our cloud hosting platform, so you won’t need to do anything on your end to turn it on. The sole requirement is that the given domain should be hosted in a website hosting account on our platform using our NS and MX records, so that the emails will go through our mail servers. The private key will be generated on the server and the TXT record, which contains the public key, will be published to the Domain Name System automatically, so you will not need to do anything manually on your end in order to enable this option. The DomainKeys Identified Mail authentication system will permit you to send credible e-mail messages, so if you’re sending a newsletter or offers to customers, for example, your emails will always reach their target destination, whereas unauthorized 3rd parties will not be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DomainKeys Identified Mail activated by default, so in case you select a semi-dedicated package and you add a domain using our name servers through your Hepsia Control Panel, the records required for the authentication system will be set up automatically – a private key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the Domain Name System. As the DKIM protection is set up for a particular domain, all e-mail addresses created using it will have a signature, so you won’t need to worry that the messages that you send out may not be delivered to their target email address or that someone may fake any of your addresses and attempt to scam/spam people. This may be very essential when you rely on email communication in your business, since your colleagues and/or customers will be able to distinguish real emails from false ones.
