DomainKeys Identified Mail (DKIM) is an authentication system used to verify that an e-mail message has been sent by an authorized server or person. A digital signature is added to the header of the message using a private encryption key. When the email message is received, a public key that is available in the global Domain Name System is used to validate who actually sent it and if its content has been altered in any way. The fundamental job of DomainKeys Identified Mail is to stop the widespread spam and scam emails, as it makes it impossible to fake an email address. If an email 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 message at all, or you’ll get it with a warning that most probably it is not a genuine one. It depends on email providers what exactly will happen with an email message which fails the signature check. DKIM will also offer you an extra layer of safety when you communicate with your business allies, for instance, since they can see that all the emails that you exchange are authentic and have not been meddled with in the meantime.
DomainKeys Identified Mail in Shared Hosting
The DomainKeys Identified Mail functionality is activated by default for all domain names that are hosted in a shared hosting
account on our cloud web hosting platform, so you will not have to do anything yourself to turn it on. The only requirement is that the given domain name should be hosted in a hosting account on our end using our MX and NS resource records, so that the emails will go through our mail servers. The private encryption key will be created on the server and the TXT resource record, which includes the public key, will be published to the DNS database automatically, so you won’t need to do anything manually on your end in order to enable this option. The DomainKeys Identified Mail authentication system will permit you to send trustworthy e-mails, so if you’re sending a newsletter or offers to clients, for instance, your emails will always reach their target audience, whereas unsolicited third parties won’t be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
All required DomainKeys Identified Mail records will be created automatically by our cloud platform when you add a domain as hosted in your semi-dedicated server
account, so in case you choose to get a semi-dedicated plan, you won’t need to configure anything to be able to take advantage of the email authentication system. The domain name should use our name servers so that its DNS records can be managed on our end and in case this requirement is fulfilled, a private cryptographic key will be created on our email servers and a public key will be sent to the global DNS database by a special TXT resource record. All addresses that you set up with the domain name will be protected by DKIM, which will make it impossible for 3rd parties to fake any address. Both you and your colleagues or customers can benefit from this service, as it will guarantee a much higher level of safety for your e-correspondence.
