DomainKeys Identified Mail, or DKIM, is a method for checking the authenticity of an email message by using a digital signature. When DKIM is enabled for a certain domain, a public cryptographic key is published to the global Domain Name System and a private one is stored on the mail server. If a new email message is sent, a signature is issued using the private key and when the email is received, that signature is ‘scanned’ by the incoming mail server using the public key. Thus, the receiver can easily tell if the email is legitimate or if the sender’s address has been forged. A discrepancy will appear if the content of the email has been changed on its way as well, so DKIM can also be used to ensure that the sent and the received emails are identical and that nothing has been added or deleted. This authentication system will strengthen your email safety, as you can confirm the genuineness of the important email messages that you get and your associates can do the exact same thing with the emails that you send them. Depending on the given email service provider’s policy, a message that fails the check may be deleted or may show up in the recipient’s mailbox with a warning alert.

DomainKeys Identified Mail in Cloud Website Hosting

If you purchase any of the Linux cloud website hosting service that we’re offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you register under your shared web hosting account, so you won’t have to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our MX and NS resource records (so that the emails related to this domain name will be handled by our cloud hosting platform), a private key will be created instantaneously on our email servers and a TXT record with a public key will be sent to the global DNS database. All addresses set up using this domain will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target audience and the recipients will be sure that the messages are authentic, because the DomainKeys Identified Mail option makes it impossible for unauthorized individuals to forge your e-mail addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers 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 authentication system will be set up automatically – a private key on our mail servers for the electronic signature and a TXT record carrying the public key for the Domain Name System. Since the DKIM protection is set up for a certain domain name, all addresses created with it will have a signature, so you won’t need to worry that the emails that you send may not be delivered to their destination address or that somebody may forge any of your email addresses and attempt to spam/scam people. This may be quite important if you use electronic communication in your business, as your colleagues and/or customers will be able to distinguish authentic messages from forged ones.
