DomainKeys Identified Mail

DomainKeys Identified Mail (DKIM) - discover more about it, what it does, the way it works and how to activate it for your mailboxes.

DomainKeys Identified Mail (DKIM) is an email validation system used to prove that an email message has been sent by an authorized mail server or individual. A digital signature is added to the header of the email message by using a private key. When the email message is received, a public key that’s available in the global DNS database is used to validate who exactly sent it and whether its content has been altered in any way. The essential job of DKIM is to hinder the widespread scam and spam emails, 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 instance, but the signature does not correspond, you will either not get the email message at all, or you will receive it with a warning notification that most likely it’s not an authentic one. It depends on email service providers what exactly will happen with an email message which fails to pass the signature examination. DKIM will also provide you with an additional layer of security when you communicate with your business associates, for example, as they can see for themselves that all the emails that you exchange are genuine and have not been modified on their way.

DomainKeys Identified Mail in Shared Website Hosting

The DomainKeys Identified Mail option is enabled by default for all domain names that are hosted in a shared website hosting account on our cloud web 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 an account on our end using our NS and MX records, so that the email messages will go through our mail servers. The private cryptographic key will be generated on the server and the TXT record, which contains the public key, will be published to the DNS system automatically, so you won’t need to do anything manually on your end in order to enable this feature. The DKIM email validation system will allow you to send credible messages, so if you are sending a newsletter or offers to clients, for instance, your emails will always reach their target destination, whereas unsolicited 3rd parties won’t be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

All obligatory DKIM records will be created automatically by our cloud hosting platform when you add a domain name as hosted in your semi-dedicated server account, so in case you choose to purchase a semi-dedicated server package, you will not need to set up anything to be able to take advantage of the email validation system. The domain name must use our name servers so that its DNS resource records can be managed by our company and provided that this precondition is satisfied, a private cryptographic key will be created on our email servers and a public key will be published to the global Domain Name System by a special TXT resource record. All addresses that you set up using the domain will be protected by DomainKeys Identified Mail, which will make it impossible for third parties to forge any address. Both you and your partners or clients can benefit from this functionality, as it will ensure a much higher safety level for your electronic communication.
