DomainKeys Identified Mail, or DKIM, is a method for validating the genuineness of an email by using a digital signature. When DomainKeys Identified Mail is enabled for a certain domain name, a public cryptographic key is published to the global Domain Name System and a private one is stored on the email server. When a new message is sent, a signature is issued using the private key and when the email message is received, the signature is verified by the receiving server using the public key. Thus, the receiver can easily discern if the email message is legitimate or if the sender’s email address has been forged. A mismatch will occur if the content of the email has been modified in the meantime as well, so DKIM can also be used to ensure that the sent and the received messages are identical and that nothing has been attached or erased. This email validation system will strengthen your email safety, since you can validate the genuineness of the important email messages that you receive and your colleagues can do the same with the messages that you send them. Depending on the given mail service provider’s policy, an email that fails to pass the check may be deleted or may enter the recipient’s mailbox with a warning sign.

DomainKeys Identified Mail in Shared Hosting

If you host a domain name in a shared hosting account from us, all the necessary records for using the DomainKeys Identified Mail option will be added by default. This will happen as soon as you add the domain name in , on the condition that the domain also uses our NS records. A private cryptographic key will be created on our mail servers, while a public key will be published to the DNS system automatically using the TXT resource record. Thus, you won’t have to do anything manually and you’ll be able to take full advantage of all the benefits of this authentication system – your emails will reach any audience without being rejected and nobody will be able to send out messages faking your addresses. The latter is really important if the essence of your Internet presence involves sending out regular newsletters or offers via email to potential and existing clients.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated hosting plans come with DomainKeys Identified Mail activated by default, so in case you opt for this type of hosting and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private encryption key on our mail servers for the digital signature and a TXT resource record carrying the public key for the global DNS database. As the DKIM protection is set up for a specific domain name, all addresses created with it will carry a signature, so you won’t need to worry that the email messages that you send may not reach their target email address or that someone may forge any of your email addresses and attempt to spam/scam people. This may be quite essential if you rely on electronic communication in your business, since your associates and/or customers will be able to distinguish real emails from spoofed ones.
