DomainKeys Identified Mail, or DKIM, is a system for validating the genuineness of an email by using an e-signature. When DomainKeys Identified Mail is enabled for a particular domain, a public key is published to the global DNS database and a private one is kept on the mail server. If a new message is sent, a signature is generated using the private key and when the email message is delivered, that signature is verified by the POP3/IMAP server using the public key. In this way, the receiver can easily know if the email message is legitimate or if the sender’s address has been forged. A mismatch will occur 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 received messages are identical and that nothing has been attached or deleted. This validation system will strengthen your email safety, as you can verify the genuineness of the important emails that you receive and your partners can do likewise with the messages that you send them. Depending on the particular email provider’s adopted policies, an email message that fails to pass the check may be erased or may emerge in the recipient’s inbox with a warning flag.

DomainKeys Identified Mail in Website Hosting

The DomainKeys Identified Mail option is pre-activated for all domains that are hosted in a website hosting account on our cloud platform, so you will not need to do anything yourself to activate it. The only requirement is that the particular domain should be hosted in an account on our platform using our MX and NS resource records, so that the e-mail messages will go through our email servers. The private key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global Domain Name System automatically, so you will not have to do anything manually on your end in order to activate this functionality. The DKIM authentication system will allow you to send trustable e-mail messages, so if you’re sending offers or a newsletter to clients, for instance, your emails will always reach their target audience, whereas unsolicited 3rd parties will not be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DomainKeys Identified Mail activated by default, so in case you choose a semi-dedicated package 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 encryption key on our mail servers for the e-signature and a TXT resource record carrying the public key for the global Domain Name System. Since the protection is set up for a specific domain, all e-mail addresses created with it will have a signature, so you won’t have to worry that the email messages that you send may not be delivered to their destination address or that somebody may spoof any of your addresses and try to scam/spam people. This may be very important in case you use email communication in your business, as your associates and/or clients will be able to distinguish legitimate emails from forged ones.
