DomainKeys Identified Mail (DKIM) is an email authentication system used to prove that an email message has been sent by an authenticated person or mail server. An e-signature is attached to the header of the email message using a private key. When the email message is received, a public key that’s available in the global DNS database is used to validate who exactly sent it and if the content has been edited in any way. The essential task of DKIM is to block the widely spread spam and scam messages, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank, for example, but the signature doesn’t correspond, you will either not receive the email message at all, or you will get it with an alert that most probably it’s not a genuine one. It depends on mail service providers what exactly will happen with an email that fails the signature check. DKIM will also give you an extra security layer when you communicate with your business associates, for instance, since they can see for themselves that all the e-mail messages that you send are authentic and have not been modified in the meantime.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail option is pre-enabled for all domains that are hosted in a shared hosting account on our cloud hosting platform, so you will not have to do anything yourself to activate it. The only condition is that the particular domain name should be hosted in a hosting account on our platform using our MX and NS resource records, so that the e-mail messages will go through our mail servers. The private encryption key will be generated on the server and the TXT record, which contains 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 functionality. The DomainKeys Identified Mail email validation system will enable you to send credible e-mails, so if you are sending a newsletter or offers to customers, for example, your email messages will always reach their target audience, whereas unsolicited third parties will not be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DomainKeys Identified Mail activated by default, so if you opt for a semi-dedicated hosting package and you add a domain using our name servers via your Hepsia Control Panel, the records required for the authentication system will be created automatically – a private encryption key on our mail servers for the electronic signature and a TXT record carrying the public key for the Domain Name System. Since the protection is set up for a specific domain name, all email addresses created under it will have a signature, so you will not have to worry that the email messages that you send out may not be delivered to their destination email address or that somebody may spoof any of your email addresses and attempt to spam/scam people. This may be very essential if you use email communication in your business, since your partners and/or customers will be able to distinguish real email messages from counterfeit ones.
