DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an email has been sent by an authenticated email server or individual. A digital signature is attached to the header of the message by using a private cryptographic key. When the email is received, a public key that’s available in the global Domain Name System is used to validate who exactly sent it and if the content has been modified in any way. The chief job of DKIM is to hamper the widespread spam and scam email messages, as it makes it impossible to fake an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for example, but the signature doesn’t correspond, you will either not get the email message at all, or you will get it with a warning alert that most likely it is not legitimate. It depends on email service providers what exactly will happen with an email message that fails the signature examination. DKIM will also provide you with an additional protection layer when you communicate with your business partners, for instance, since they can see that all the e-mails that you exchange are legitimate and have not been modified on their way.

DomainKeys Identified Mail in Shared Web Hosting

The DomainKeys Identified Mail option is pre-activated for all domains that are hosted in a shared web hosting account on our cloud hosting platform, so you won’t have to do anything yourself to activate it. The only requirement is that the particular domain name should be hosted in a hosting account on our end using our NS and MX resource records, so that the e-mails will go through our email servers. The private encryption key will be generated on the server and the TXT resource record, which contains the public key, will be published to the DNS system automatically, so you will not need to do anything manually on your end in order to enable this functionality. The DKIM authentication system will permit you to send out trustworthy emails, so if you are sending offers or a newsletter to customers, for example, your email messages will always reach their target destination, whereas unsolicited third parties won’t be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

All mandatory DomainKeys Identified Mail records will be created automatically by our cloud hosting platform when you add a domain name as hosted in a semi-dedicated server account, so in case you choose to get a semi-dedicated hosting plan, you will not need to set up anything to be able to use the email validation system. The domain must use our name servers in order for its DNS resource records to be managed on our end and in case this condition is fulfilled, a private cryptographic key will be generated on our mail servers and a public key will be sent to the Domain Name System by a special TXT resource record. All addresses that you create using the domain will be protected by DomainKeys Identified Mail, which will make it impossible for third parties to spoof any address. Both you and your associates or clients can take advantage of this service, as it will guarantee a much higher level of protection for your email correspondence.
