DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email message by using an electronic signature. When DomainKeys Identified Mail is activated for a given domain, a public cryptographic key is published to the global Domain Name System and a private one is stored on the mail server. When a new message is sent, a signature is generated using the private key and when the message is received, the signature is authenticated by the POP3/IMAP mail server using the public key. In this way, the receiver can easily know if the email is genuine or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email message has been edited on its way as well, so DKIM can also be used to make sure that the sent and the received messages are identical and that nothing has been attached or deleted. This email validation system will enhance your email security, since you can verify the authenticity of the important email messages that you receive and your associates can do the exact same thing with the emails that you send them. Depending on the particular email provider’s adopted policies, an email that fails to pass the check may be erased or may reach the recipient’s inbox with a warning symbol.

DomainKeys Identified Mail in Hosting

If you purchase one of the hosting that we offer, the DomainKeys Identified Mail option will be enabled as standard for any domain that you register under your hosting account, so you won’t need to create any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our NS and MX resource records (so that the emails related to this domain name will be handled by our cloud 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 global DNS database. All addresses set up using this domain name will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target destination and the recipients will know that the messages are legitimate, since the DKIM functionality makes it impossible for unauthorized people to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated services come with DomainKeys Identified Mail activated by default, so in case you choose a semi-dedicated package and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private cryptographic key on our email servers for the electronic 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, all e-mail addresses created with it will have a signature, so you won’t need to worry that the email messages that you send may not be delivered to their destination address or that someone may fake any of your email addresses and try to spam/scam people. This may be very important if you use email communication in your business, since your partners and/or customers will be able to distinguish legitimate emails from phony ones.
