DomainKeys Identified Mail, or DKIM, is a system for confirming the authenticity of an email using a digital signature. When DKIM is enabled for a given domain, a public cryptographic key is published to the global Domain Name System and a private one is kept on the email server. If a new email is sent, a signature is generated using the private key and when the email is delivered, the signature is authenticated by the incoming POP3/IMAP email server using the public key. In this way, the recipient can easily know if the email message is genuine or if the sender’s address has been forged. A mismatch will occur if the content of the email message has been edited on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received email messages are identical and that nothing has been attached or deleted. This email authentication system will heighten your email safety, since you can verify the authenticity of the important emails that you receive and your colleagues can do the exact same thing with the emails that you send them. Depending on the given email provider’s policy, a message that fails the test may be erased or may be delivered to the receiver’s mailbox with a warning symbol.
DomainKeys Identified Mail in Web Hosting
In case you host a domain in a web hosting account from our company, all the necessary records for using the DomainKeys Identified Mail functionality will be created by default. This will happen the moment you add the domain name in the Hosted Domains section of the Hepsia Control Panel, as long as the domain also uses our NS records. A private encryption key will be generated on our email servers, while a public key will be added to the global DNS database automatically by using the TXT resource record. Thus, you will not have to do anything manually and you will be able to enjoy all the benefits of this authentication system – your email messages will be sent to any target audience without being denied and no one will be able to send emails forging your email addresses. The latter is really important in case the nature of your Internet presence suggests sending regular newsletters or offers via email to potential and current customers.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so in case you opt for a semi-dedicated server plan and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the authentication system will be set up automatically – a private cryptographic key on our email servers for the e-signature and a TXT record carrying the public key for the DNS system. As the DKIM protection is set up for a given domain name, all addresses created using it will have a signature, so you won’t have to worry that the messages that you send may not be delivered to their target email address or that someone may fake any of your addresses and try to scam/spam people. This may be really essential if you rely on electronic communication in your business, since your colleagues and/or customers will be able to distinguish genuine email messages from false ones.
