DomainKeys Identified Mail (DKIM) is an authentication system used to confirm that an e-mail message has been sent by an authorized person or email server. A digital signature is added to the message’s header by using a private cryptographic key. When the email message is received, a public key that is available in the global DNS database is used to check who actually sent it and whether its content has been edited in some way. The essential function of DKIM is to avert the widely spread scam and spam emails, 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 or financial institution, for instance, but the signature does not correspond, you will either not receive the email at all, or you’ll get it with a warning notification that most likely it is not a legitimate one. It depends on email service providers what exactly will happen with an email message which fails to pass the signature test. DKIM will also offer you an extra layer of security when you communicate with your business allies, for example, as they can see that all the messages that you exchange are legitimate and have not been modified on their way.

DomainKeys Identified Mail in Shared Website Hosting

If you obtain one of the shared website hosting that we offer, the DomainKeys Identified Mail feature will be activated as standard for any domain name that you register under your web hosting account, so you will not need to set up any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our NS and MX records (so that the email messages associated with this domain will be handled by our cloud platform), a private key will be generated immediately on our email servers and a TXT record with a public key will be sent to the global DNS system. All email addresses created with this domain will be protected by DomainKeys Identified Mail, so if you send emails such as periodic newsletters, they will reach their target destination and the recipients will know that the messages are legitimate, since the DKIM option makes it impossible for unauthorized parties to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so if you opt for a semi-dedicated package and you add a domain using our name servers through your Hepsia Control Panel, the records required for the email authentication system will be created automatically – a private cryptographic key on our mail servers for the digital signature and a TXT resource record carrying the public key for the global DNS database. As the protection is set up for a specific domain name, all e-mail addresses created under it will have a signature, so you will not have to worry that the messages that you send out may not reach their destination email address or that somebody may fake any of your email addresses and try to scam/spam people. This may be really important if you use e-communication in your business, as your colleagues and/or customers will be able to distinguish legitimate messages from false ones.
