DomainKeys Identified Mail, or DKIM, is a system for validating the authenticity of an email using an e-signature. When DKIM is enabled for a particular domain, a public encryption key is published to the global Domain Name System and a private one is stored on the email server. When a new email message is sent, a signature is issued using the private key and when the message is received, that signature is authenticated by the POP3/IMAP mail server using the public key. Thus, the recipient can easily distinguish if the email message is legitimate or if the sender’s address has been spoofed. A mismatch will occur if the content of the email message has been changed on its way as well, so DKIM can also be used to ensure that the sent and the received messages are identical and that nothing has been added or erased. This validation system will strengthen your email safety, as you can verify the genuineness of the important email messages that you get and your colleagues can do the same with the messages that you send them. Based on the given mail service provider’s adopted policy, an email that fails to pass the examination may be deleted or may end up in the recipient’s inbox with a warning.

DomainKeys Identified Mail in Shared Web Hosting

If you obtain any of the shared web hosting that we’re offering, the DomainKeys Identified Mail option will be enabled by default for any domain that you add to your shared website hosting account, so you will not have to set up any records or to do anything manually. When a domain name is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our MX and NS records (so that the emails related to this domain will be handled by our cloud hosting platform), a private key will be created instantly on our email servers and a TXT resource record with a public key will be sent to the DNS database. All email addresses created with this domain will be protected by DKIM, so if you send out email messages such as periodic newsletters, they will reach their target audience and the recipients will be sure that the messages are authentic, since the DKIM functionality makes it impossible for unsolicited individuals to spoof your e-mail addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

All necessary DKIM records will be created automatically by our cloud platform when you add a domain name as hosted in your semi-dedicated server account, so in case you decide to order a semi-dedicated plan, you will not have to configure anything to be able to use the email validation system. The domain must use our name servers so that its DNS resource records can be managed on our end and provided that this requirement is satisfied, a private encryption key will be generated on our mail servers and a public key will be published to the DNS system by a special TXT record. All email addresses that you set up using the domain name will be protected by DKIM, which will make it impossible for 3rd parties to fake any email address. Both you and your partners or clients can benefit from this option, as it will ensure a higher security level for your e-correspondence.
