DomainKeys Identified Mail, or DKIM, is a method for validating the genuineness of an email using a digital signature. When DKIM is enabled for a given domain name, a public cryptographic key is published to the global DNS database and a private one is stored on the email server. When a new message is sent, a signature is issued using the private key and when the message is received, that signature is authenticated by the incoming POP3/IMAP email server using the public key. In this way, the recipient can easily know if the message is legitimate or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email has been modified in the meantime as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received emails are identical and that nothing has been attached or removed. This email authentication system will increase your email safety, since you can confirm the genuineness of the important email messages that you get and your colleagues can do likewise with the email messages that you send them. Based on the particular mail service provider’s policy, an email message that fails to pass the test may be removed or may end up in the recipient’s inbox with a warning notification.

DomainKeys Identified Mail in Shared Website Hosting

The DomainKeys Identified Mail functionality is activated by default for all domain names that are hosted in a shared website hosting account on our cloud platform, so you will not have to do anything yourself to activate it. The sole requirement is that the given domain should be hosted in a website hosting account on our platform using our MX and NS resource records, so that the e-mail messages will go through our mail servers. The private cryptographic key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global DNS system automatically, so you won’t have to do anything manually on your end in order to enable this feature. The DomainKeys Identified Mail authentication system will allow you to send out trustable e-mails, so if you are sending a newsletter or offers to clients, for example, your email messages will always reach their target viewers, while unauthorized third parties won’t be able to forge your email addresses.
