DomainKeys Identified Mail (DKIM) is an authentication system used to check that an e-mail message has been sent by an authorized server or person. A digital signature is attached to the header of the message by using a private encryption key. When the email message is received, a public key that is available in the global DNS database is used to confirm who exactly sent it and whether the content has been changed in any way. The chief job of DKIM is to obstruct the widely spread scam and spam emails, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank or financial institution, for instance, but the signature does not correspond, you will either not get the email message at all, or you’ll receive it with a warning alert that most likely it’s not an authentic one. It depends on email service providers what exactly will happen with an email message that fails to pass the signature examination. DomainKeys Identified Mail will also provide you with an extra protection layer when you communicate with your business allies, for instance, since they can see for themselves that all the email messages that you send are legitimate and have not been tampered with on their way.
DomainKeys Identified Mail in Hosting
When you purchase one of the Linux hosting packages that we are offering, the DomainKeys Identified Mail functionality will be enabled by default for any domain name that you add to your shard hosting account, so you will not have to create any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our MX and NS records (so that the emails related to this domain name will be handled by our cloud web hosting platform), a private encryption key will be created right away on our email servers and a TXT record with a public key will be sent to the global Domain Name System. All addresses set up using this domain name will be protected by DomainKeys Identified Mail, so if you send out emails such as regular newsletters, they will reach their target destination and the recipients will be sure that the messages are legitimate, as the DKIM functionality makes it impossible for unauthorized individuals to spoof your e-mail addresses.
