DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email message using a digital signature. When DKIM is activated for a certain domain name, a public encryption key is published to the global DNS database and a private one is kept 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 authenticated by the POP3/IMAP mail server using the public key. Thus, the receiver can easily distinguish if the email message is legitimate or if the sender’s address has been spoofed. A mismatch will occur if the content of the email message has been altered in the meantime as well, so DKIM can also be used to make sure that the sent and the delivered emails are identical and that nothing has been added or removed. This authentication system will increase your email security, since you can confirm the legitimacy of the important email messages that you get and your colleagues can do the exact same thing with the email messages that you send them. Depending on the given email service provider’s policies, an email message that fails the examination may be removed or may appear in the receiver’s mailbox with a warning sign.

DomainKeys Identified Mail in Cloud Website Hosting

The DomainKeys Identified Mail functionality is pre-activated for all domain names that are hosted in a cloud website hosting account on our cloud web hosting platform, so you won’t need to do anything on your end to activate it. The only requirement is that the given domain name should be hosted in a web hosting account on our platform using our MX and NS records, so that the emails will go through our mail servers. The private encryption key will be created on the server and the TXT record, which contains the public key, will be published to the DNS system automatically, so you won’t have to do anything manually on your end in order to activate this feature. The DKIM email authentication system will permit you to send out credible e-mail messages, so if you are sending a newsletter or offers to customers, for instance, your emails will always reach their target audience, whereas unsolicited third parties will not 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 in case you pick a semi-dedicated hosting package and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the email validation system will be created automatically – a private cryptographic key on our email servers for the e-signature and a TXT resource record carrying the public key for the DNS system. As the DKIM protection is set up for a given domain name, all e-mail addresses created using it will have a signature, so you won’t have to worry that the emails that you send may not reach their destination address or that somebody may forge any of your email addresses and attempt to spam/scam people. This may be really essential if you rely on email communication in your business, since your colleagues and/or clients will be able to distinguish legitimate emails from forged ones.
