DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an email message has been sent by an authorized person or server. An e-signature is attached to the header of the email 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 check who exactly sent it and if the content has been modified in some way. The fundamental task of DKIM is to block the widespread spam and scam messages, as it makes it impossible to forge an email address. If an email message is sent from an email address claiming to belong to your bank, for instance, but the signature does not match, you will either not get the email message at all, or you will receive it with a notification that most likely it is not genuine. It depends on mail service providers what exactly will happen with an email message which fails the signature check. DKIM will also give you an added protection layer when you communicate with your business partners, for instance, since they can see for themselves that all the email messages that you exchange are authentic and haven’t been modified on their way.
DomainKeys Identified Mail in Shared Website Hosting
If you order one of the shared website hosting plans that we’re offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain that you add to your shared web hosting account, so you won’t need to set up any records or to activate anything manually. When a domain is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our NS and MX resource records (so that the emails associated with this domain will be handled by our cloud platform), a private cryptographic key will be issued momentarily on our mail servers and a TXT resource record with a public key will be sent to the global Domain Name System. All addresses set up with this domain name will be protected by DomainKeys Identified Mail, so if you send out emails such as periodic newsletters, they will reach their target audience and the recipients will know that they are genuine, because the DKIM feature makes it impossible for unauthorized people to spoof your email addresses.
