DomainKeys Identified Mail

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

DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an e-mail message has been sent by an authorized person or email server. An electronic signature is attached to the header of the email message by using a private key. When the email is received, a public key that’s available in the global Domain Name System is used to confirm who exactly sent it and if the content has been altered in some way. The prime function of DomainKeys Identified Mail is to hinder the widely spread scam and spam emails, 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 doesn’t match, you will either not get the message at all, or you’ll receive it with a warning alert that most likely it’s not an authentic one. It depends on mail service providers what exactly will happen with an email that fails the signature check. DKIM will also offer you an additional protection layer when you communicate with your business associates, for example, since they can see that all the messages that you exchange are authentic and haven’t been tampered with in the meantime.

DomainKeys Identified Mail in Cloud Hosting

You’ll be able to make the most of DomainKeys Identified Mail with each Linux cloud hosting that we are offering without having to do anything in particular, since the mandatory records for using this email authentication system are set up automatically by our web hosting platform when you add a domain to an existing web hosting account through the Hepsia Control Panel. As long as the given domain uses our name server records, a private key will be issued and kept on our email servers and a TXT resource record with a public key will be sent to the DNS database. In case you send regular messages to customers or business collaborators, they will always be received and no unsolicited party will be able to spoof your address and make it seem like you’ve sent a particular email message.

DomainKeys Identified Mail in Semi-dedicated Hosting

All obligatory DKIM records will be created automatically by our cloud hosting platform when you add a domain as hosted in a semi-dedicated server account, so in case you choose to buy a semi-dedicated hosting package, you will not need to set up anything to be able to use the email authentication system. The domain name must use our name servers in order for its DNS records to be managed by us and as long as this requirement is answered, a private encryption key will be created on our email servers and a public key will be added to the DNS database by a special TXT resource record. All email addresses that you create with the domain name will be protected by DKIM, which will make it impossible for third parties to spoof any email address. Both you and your partners or customers can take advantage of this functionality, as it will guarantee a higher security level for your online correspondence.
