DomainKeys Identified Mail, or DKIM, is a system for checking the legitimacy of an email using a digital signature. When DomainKeys Identified Mail is enabled for a given domain, a public cryptographic key is published to the global Domain Name System and a private one is kept on the mail server. When a new email message is sent, a signature is generated using the private key and when the message is delivered, the signature is validated by the incoming POP3/IMAP email server using the public key. Thus, the recipient can easily distinguish if the email is authentic or if the sender’s email address has been spoofed. A discrepancy will occur if the content of the email message has been altered 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, since you can confirm the legitimacy of the important email messages that you receive and your colleagues can do the exact same thing with the emails that you send them. Depending on the particular email service provider’s policy, an email that fails to pass the examination may be deleted or may be delivered to the receiver’s inbox with a warning symbol.

DomainKeys Identified Mail in Cloud Website Hosting

When you buy any of the cloud website hosting that we are offering, the DomainKeys Identified Mail functionality will be enabled by default for any domain name that you register under your website hosting account, so you won’t have to create any records or to activate anything manually. When a domain name 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 will be handled by our cloud platform), a private encryption key will be issued straight away on our email servers and a TXT record with a public key will be sent to the global Domain Name System. All email addresses created using this domain will be protected by DomainKeys Identified Mail, so if you send out email messages such as regular newsletters, they will reach their target destination and the recipients will be sure that they are genuine, because the DomainKeys Identified Mail option makes it impossible for unauthorized parties to spoof your email addresses.
