DomainKeys Identified Mail, or DKIM, is a system for verifying the legitimacy of an email by using a digital signature. When DKIM is activated for a given domain name, a public encryption key is published to the global DNS database and a private one is stored on the email server. When a new email is sent, a signature is generated using the private key and when the email is delivered, that signature is validated by the POP3/IMAP server using the public key. Thus, the recipient can easily discern if the email is genuine or if the sender’s email address has been forged. A mismatch will occur if the content of the email has been edited on its way 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 erased. This email authentication system will strengthen your email security, since you can confirm the legitimacy of the important email messages that you receive and your partners can do the same with the emails that you send them. Depending on the given email provider’s policy, an email message that fails to pass the check may be removed or may emerge in the recipient’s inbox with a warning sign.

DomainKeys Identified Mail in Shared Website Hosting

The DomainKeys Identified Mail functionality is pre-activated for all domains that are hosted in a shared website hosting account on our cloud website hosting platform, so you will not have to do anything on your end to enable it. The sole requirement is that the particular domain name should be hosted in an account on our end using our NS and MX resource records, so that the e-mails will go through our mail servers. The private key will be created on the server and the TXT record, which includes the public key, will be published to the global DNS database automatically, so you will not need to do anything manually on your end in order to enable this functionality. The DomainKeys Identified Mail authentication system will enable you to send out trustworthy e-mails, so if you’re sending offers or a newsletter to customers, for example, your email messages will always reach their target audience, whereas unsolicited third parties won’t be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated hosting plans come with DomainKeys Identified Mail activated by default, so if you choose a semi-dedicated hosting plan and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the authentication system will be set up automatically – a private key on our email servers for the electronic signature and a TXT resource record carrying the public key for the global Domain Name System. As the DKIM protection is set up for a certain domain name, all addresses created using it will carry a signature, so you won’t have to worry that the messages that you send may not reach their target email address or that someone may forge any of your addresses and attempt to scam/spam people. This may be rather essential if you rely on e-communication in your business, as your colleagues and/or clients will be able to distinguish genuine email messages from counterfeit ones.
