DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an e-mail message has been sent by an authenticated server or person. A digital signature is added to the message’s header by using a private key. When the email is received, a public key that is available in the global Domain Name System is used to check who actually sent it and if its content has been altered in some way. The principal function of DKIM is to stop the widely spread scam and spam email messages, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature doesn’t match, you will either not get the message at all, or you will receive it with a warning note that most likely it is not genuine. It depends on email service providers what exactly will happen with an email message that fails to pass the signature test. DKIM will also give you an added security layer when you communicate with your business allies, for example, since they can see for themselves that all the e-mails that you exchange are legitimate and have not been manipulated on their way.
DomainKeys Identified Mail in Semi-dedicated Hosting
All obligatory DomainKeys Identified Mail records will be set up automatically by our cloud web hosting platform when you add a domain as hosted in a semi-dedicated server account, so in case you choose to order a semi-dedicated hosting package, you will not need to set up anything to be able to take advantage of the email authentication system. The domain name must use our name servers in order for its DNS records to be managed on our end and as long as this requirement is met, a private encryption key will be created on our mail servers and a public key will be published to the global DNS system by a special TXT record. All email addresses that you set up using the domain name will be protected by DomainKeys Identified Mail, which will make it impossible for 3rd parties to spoof any address. Both you and your associates or clients can take advantage of this service, since it will ensure a much higher level of safety for your email correspondence.
