DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an e-mail message has been sent by an authenticated server or individual. An electronic signature is added to the header of the email by using a private key. When the message is received, a public key that’s available in the global Domain Name System is used to check who actually sent it and if its content has been edited in any way. The principal purpose of DomainKeys Identified Mail is to block the widely spread scam and spam messages, as it makes it impossible to fake an email address. If an email is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature does not match, you will either not receive the email at all, or you’ll get it with a notification that most likely it’s not an authentic one. It depends on email providers what exactly will happen with an email which fails to pass the signature check. DKIM will also give you an added layer of safety when you communicate with your business associates, for example, since they can see for themselves that all the emails that you exchange are authentic and have not been meddled with in the meantime.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail functionality is pre-activated for all domains that are hosted in a cloud hosting account on our cloud servers, so you won’t have to do anything on your end to enable it. The sole condition is that the particular domain should be hosted in a hosting account on our end using our NS and MX resource records, so that the email messages will go through our email servers. The private 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 DomainKeys Identified Mail email authentication system will allow you to send out credible e-mails, so if you’re sending a newsletter or offers to customers, for example, your emails will always reach their target audience, while unsolicited third parties will not be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated services come with DomainKeys Identified Mail enabled by default, so in case you choose this type of hosting and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private key on our mail servers for the electronic signature and a TXT record carrying the public key for the Domain Name System. As the DKIM protection is set up for a certain domain name, all email addresses created using it will have a signature, so you won’t need to worry that the emails that you send out may not reach their destination address or that someone may fake any of your addresses and attempt to scam/spam people. This may be quite important if you use electronic communication in your business, since your colleagues and/or customers will be able to distinguish genuine messages from false ones.
