DomainKeys Identified Mail, or DKIM, is a method for confirming the legitimacy of an email message using an electronic signature. When DKIM is enabled for a given domain name, a public key is published to the global DNS 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 message is delivered, that signature is ‘scanned’ by the incoming POP3/IMAP server using the public key. Thus, the receiver can easily recognize if the email message is authentic or if the sender’s address has been forged. A discrepancy will occur if the content of the email message has been changed in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered messages are identical and that nothing has been added or erased. This validation system will boost your email security, as you can validate the authenticity of the important emails that you get and your associates can do likewise with the messages that you send them. Based on the particular email provider’s adopted policy, an email that fails the check may be erased or may reach the recipient’s inbox with a warning notification.

DomainKeys Identified Mail in Cloud Hosting

When you get any of the Linux cloud packages that we’re offering, the DomainKeys Identified Mail functionality will be enabled by default for any domain name that you add to your shared account, so you will not need to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our MX and NS resource records (so that the email messages related to this domain will be handled by our cloud web hosting platform), a private encryption key will be issued immediately on our email servers and a TXT resource record with a public key will be sent to the Domain Name System. All addresses created using this domain name will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target audience and the receivers will be sure that the messages are legitimate, as the DKIM feature makes it impossible for unauthorized parties to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting packages come with DKIM activated by default, so in case you choose a semi-dedicated plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the validation system will be set up automatically – a private encryption key on our email servers for the digital signature and a TXT resource record carrying the public key for the global Domain Name System. Since the protection is set up for a certain domain, all e-mail addresses created with it will carry a signature, so you will not need to worry that the email messages that you send out may not be delivered to their target email address or that somebody may fake any of your email addresses and attempt to spam/scam people. This may be extremely important when you use e-communication in your business, as your partners and/or clients will be able to distinguish genuine emails from phony ones.
