DomainKeys Identified Mail (DKIM) is an authentication system used to confirm that an email has been sent by an authorized mail server or individual. An electronic signature is added to the email’s header by using a private encryption key. When the email is received, a public key that’s available in the global Domain Name System is used to validate who actually sent it and whether its content has been altered in some way. The fundamental task of DomainKeys Identified Mail is to impede the widely spread scam and spam 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, for example, but the signature does not correspond, you will either not get the email at all, or you’ll get it with a notification that most likely it is not a legitimate one. It depends on mail service providers what exactly will happen with an email message that fails to pass the signature check. DomainKeys Identified Mail will also offer you an extra protection layer when you communicate with your business associates, for example, since they can see for themselves that all the e-mails that you send are authentic and have not been tampered with in the meantime.

DomainKeys Identified Mail in Hosting

When you purchase any of the Linux hosting packages that we offer, the DomainKeys Identified Mail functionality will be activated by default for any domain name that you add to your account, so you will not need to create any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our MX and NS resource records (so that the email messages associated with this domain will be handled by our cloud web hosting platform), a private encryption key will be generated immediately on our mail servers and a TXT resource record with a public key will be sent to the DNS database. All email addresses created using this domain will be protected by DKIM, so if you send emails such as regular newsletters, they will reach their target audience and the receivers will be sure that they are authentic, because the DKIM option makes it impossible for unauthorized individuals to spoof your email addresses.
