DomainKeys Identified Mail, or DKIM, is a system for confirming the authenticity of an email message by using a digital signature. When DomainKeys Identified Mail is enabled for a given domain name, a public cryptographic key is published to the global Domain Name System and a private one is stored on the email server. If a new email message is sent, a signature is issued using the private key and when the message is delivered, that signature is ‘scanned’ by the incoming POP3/IMAP mail server using the public key. Thus, the recipient can easily know if the email is authentic or if the sender’s address has been forged. A mismatch will appear if the content of the email message has been changed in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or deleted. This email authentication system will enhance your email security, since you can validate the authenticity of the important email messages that you get and your partners can do the same with the email messages that you send them. Depending on the given email provider’s policy, a message that fails to pass the check may be erased or may show up in the recipient’s inbox with a warning sign.

DomainKeys Identified Mail in Website Hosting

When you purchase one of the Linux website hosting plans that we are offering, the DomainKeys Identified Mail option will be enabled by default for any domain that you register under your web hosting account, so you will not need to set up any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our MX and NS resource 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 mail servers and a TXT resource record with a public key will be sent to the global Domain Name System. All email addresses created with this domain name will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target audience and the recipients will be sure that they are genuine, since the DomainKeys Identified Mail option makes it impossible for unauthorized persons to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated plans come with DKIM activated by default, so if you choose a semi-dedicated server plan and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private encryption key on our email servers for the electronic signature and a TXT resource record carrying the public key for the global DNS database. Since the protection is set up for a particular domain name, all addresses created under it will have a signature, so you won’t need to worry that the messages that you send may not be delivered to their target email address or that somebody may fake any of your email addresses and try to spam/scam people. This may be extremely essential when you use e-communication in your business, since your associates and/or clients will be able to distinguish legitimate messages from false ones.
