DomainKeys Identified Mail (DKIM) is an authentication system used to check that an e-mail has been sent by an authorized mail server or individual. An electronic signature is attached to the header of the email message by using a private cryptographic key. When the email message is received, a public key that is available in the global Domain Name System is used to confirm who actually sent it and whether the content has been altered in some way. The primary purpose of DomainKeys Identified Mail is to hamper the widespread spam and scam messages, as it makes it impossible to fake an email address. If an email message is sent from an email address claiming to belong to your bank, for example, but the signature does not correspond, you will either not get the email at all, or you’ll get it with an alert that most probably it’s not authentic. It depends on email service providers what exactly will happen with an email message which fails the signature check. DomainKeys Identified Mail will also provide you with an extra layer of safety when you communicate with your business partners, for instance, as they can see for themselves that all the email messages that you send are genuine and haven’t been manipulated on their way.

DomainKeys Identified Mail in Cloud Website Hosting

The DomainKeys Identified Mail functionality is enabled by default for all domain names that are hosted in a cloud website hosting account on our cloud website hosting platform, so you won’t have to do anything yourself to enable it. The sole requirement is that the particular domain should be hosted in a website hosting account on our end using our NS and MX records, so that the e-mails will go through our email 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 DNS system automatically, so you won’t have to do anything manually on your end in order to activate this option. The DomainKeys Identified Mail email validation system will enable you to send out trustable e-mail messages, so if you’re sending a newsletter or offers to customers, for example, your emails 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 Servers

All necessary DomainKeys Identified Mail records will be created automatically by our cloud platform when you add a domain as hosted in a semi-dedicated server account, so if you decide to buy a semi-dedicated server plan, you will not need to set up anything to be able to use the email authentication system. The domain must use our name servers in order for its DNS resource records to be managed on our end and provided that this precondition is met, a private key will be generated on our mail servers and a public key will be sent to the DNS database by a special TXT resource 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 third parties to fake any address. Both you and your colleagues or customers can take advantage of this functionality, since it will guarantee a much higher security level for your electronic correspondence.
