DomainKeys Identified Mail (DKIM) is an email validation system used to confirm that an email message has been sent by an authenticated person or server. A digital signature is added to the header of the email message by using a private cryptographic key. When the 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 its content has been edited in some way. The chief job of DomainKeys Identified Mail is to impede the widespread spam and scam 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, for example, but the signature does not correspond, you will either not receive the email message at all, or you will get it with a warning that most likely it is not legitimate. It depends on email providers what exactly will happen with an email that fails to pass the signature check. DKIM will also offer you an additional layer of safety when you communicate with your business associates, for instance, as they can see for themselves that all the e-mails that you send are authentic and haven’t been modified on their way.
DomainKeys Identified Mail in Website Hosting
The DomainKeys Identified Mail functionality is pre-enabled for all domains that are hosted in a website hosting account on our cloud hosting platform, so you will not need to do anything yourself to turn it on. The only condition is that the given domain should be hosted in an account on our platform using our MX and NS resource records, so that the e-mails will go through our email servers. The private encryption key will be created on the server and the TXT record, which contains the public key, will be published to the DNS database automatically, so you won’t have to do anything manually on your end in order to enable this functionality. The DomainKeys Identified Mail email authentication system will permit you to send credible e-mail messages, so if you’re sending offers or a newsletter to customers, for example, your email messages will always reach their target audience, whereas unsolicited 3rd parties won’t be able to spoof your email addresses.
