DomainKeys Identified Mail (DKIM) is an authentication system used to prove that an e-mail has been sent by an authorized email server or individual. A digital signature is attached to the header of the email message using a private cryptographic key. When the email is received, a public key that is available in the global DNS database is used to confirm who actually sent it and whether the content has been edited in some way. The prime function of DKIM is to prevent the widespread spam and scam email messages, as it makes it impossible to fake an email address. If an email message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t match, you will either not get the message at all, or you’ll receive it with a warning notice that most probably it is not authentic. It depends on email providers what exactly will happen with an email which fails the signature examination. DomainKeys Identified Mail will also offer you an added security layer when you communicate with your business partners, for instance, as they can see for themselves that all the e-mail messages that you send are authentic and have not been modified on their way.

DomainKeys Identified Mail in Shared Web Hosting

The DomainKeys Identified Mail option is enabled by default for all domain names that are hosted in a shared web hosting account on our cloud web hosting platform, so you will not need to do anything on your end to activate it. The sole requirement is that the particular domain name should be hosted in a website hosting account on our platform using our MX and NS records, so that the e-mails will go through our mail servers. The private key will be created on the server and the TXT record, which contains the public key, will be published to the global DNS database automatically, so you won’t need to do anything manually on your end in order to activate this functionality. The DomainKeys Identified Mail validation system will allow you to send credible e-mails, so if you are sending offers or a newsletter to customers, for example, your email messages will always reach their target audience, whereas unsolicited third parties won’t be able to forge your email addresses.
