DomainKeys Identified Mail (DKIM) is a validation system used to prove that an e-mail message has been sent by an authorized person or email server. An electronic signature is added to the header of the message using a private encryption key. When the email message is received, a public key that’s available in the global DNS database is used to check who actually sent it and if its content has been changed in any way. The prime purpose of DomainKeys Identified Mail is to hinder the widely spread spam and scam email messages, 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 email at all, or you will get it with a warning alert that most likely it is not genuine. It depends on email providers what exactly will happen with an email message which fails to pass the signature test. DKIM will also provide you with an additional security layer when you communicate with your business partners, for example, as they can see that all the email messages that you send are authentic and have not been modified on their way.

DomainKeys Identified Mail in Cloud Website Hosting

The DomainKeys Identified Mail option is pre-enabled for all domain names that are hosted in a cloud website hosting account on our cloud servers, so you won’t have to do anything on your end to activate it. The sole requirement is that the given domain name should be hosted in a website hosting account on our end using our MX and NS records, so that the e-mails will go through our email servers. The private key will be generated on the server and the TXT record, which includes the public key, will be published to the global Domain Name System automatically, so you will not need to do anything manually on your end in order to activate this functionality. The DKIM validation system will allow you to send out trustable messages, so if you’re sending offers or a newsletter to customers, for instance, your emails will always reach their target destination, whereas unsolicited 3rd parties won’t be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated service come with DKIM enabled by default, so if you select a semi-dedicated plan and you add a domain using our name servers via your Hepsia Control Panel, the records required for the validation system will be set up automatically – a private cryptographic key on our mail servers for the digital signature and a TXT record carrying the public key for the global DNS system. As the protection is set up for a given domain name, all email addresses created with it will have a signature, so you will not need to worry that the emails that you send out may not reach their target email address or that someone may spoof any of your email addresses and try to spam/scam people. This may be extremely important when you use email communication in your business, since your associates and/or customers will be able to distinguish legitimate emails from counterfeit ones.
