DomainKeys Identified Mail, or DKIM, is a method for checking the genuineness of an email message using an e-signature. When DKIM is enabled for a particular domain name, a public encryption key is published to the global Domain Name System and a private one is kept on the mail server. If a new email message is sent, a signature is generated using the private key and when the email is received, the signature is ‘scanned’ by the POP3/IMAP mail server using the public key. Thus, the recipient can easily distinguish if the email message is genuine or if the sender’s address has been forged. A discrepancy 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 received email messages are identical and that nothing has been attached or removed. This authentication system will increase your email security, since you can validate the authenticity of the important email messages that you receive and your colleagues can do likewise with the email messages that you send them. Based on the particular email service provider’s policy, an email that fails to pass the check may be erased or may appear in the recipient’s mailbox with a warning alert.

DomainKeys Identified Mail in Cloud Website Hosting

The DomainKeys Identified Mail functionality is enabled by default for all domains that are hosted in a cloud website hosting account on our cloud hosting platform, so you will not have to do anything yourself to turn it on. The sole condition is that the given domain name should be hosted in a website hosting account on our end using our NS and MX records, so that the emails will go through our email servers. The private cryptographic key will be generated on the server and the TXT record, which includes the public key, will be published to the DNS system automatically, so you won’t have to do anything manually on your end in order to enable this functionality. The DomainKeys Identified Mail email validation system will allow you to send out credible e-mail messages, so if you are sending a newsletter or offers to customers, for example, your email messages will always reach their target audience, while unauthorized third parties will not be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated packages come with DKIM enabled by default, so if you opt for a semi-dedicated package and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private key on our mail servers for the electronic signature and a TXT record carrying the public key for the global DNS database. As the DKIM protection is set up for a given domain, all addresses created under it will carry a signature, so you will not have to worry that the messages that you send may not be delivered to their destination email address or that somebody may fake any of your addresses and try to spam/scam people. This may be extremely important if you use electronic communication in your business, as your associates and/or customers will be able to distinguish legitimate email messages from counterfeit ones.
