DomainKeys Identified Mail, or DKIM, is a system for validating the authenticity of an email using a digital signature. When DomainKeys Identified Mail is enabled for a specific domain, a public encryption key is published to the global DNS system and a private one is stored on the email server. When a new message is sent, a signature is generated using the private key and when the email message is delivered, that signature is validated by the incoming email server using the public key. In this way, the receiver can easily discern if the message is genuine or if the sender’s email address has been forged. A discrepancy will appear if the content of the email has been changed in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received emails are identical and that nothing has been added or removed. This validation system will strengthen your email security, as you can verify the genuineness of the important emails that you receive and your partners can do likewise with the messages that you send them. Based on the particular email provider’s adopted policy, a message that fails to pass the examination may be removed or may appear in the receiver’s inbox with a warning alert.

DomainKeys Identified Mail in Cloud Web Hosting

The DomainKeys Identified Mail option is activated by default for all domain names that are hosted in a cloud web hosting account on our cloud web hosting platform, so you will not need to do anything yourself to turn it on. The only condition is that the particular domain name should be hosted in a website hosting account on our end using our MX and NS resource records, so that the e-mails will go through our email servers. The private cryptographic key will be generated on the server and the TXT resource record, which contains the public key, will be published to the Domain Name System automatically, so you won’t have to do anything manually on your end in order to activate this feature. The DomainKeys Identified Mail email validation system will allow you to send out trustable e-mail messages, so if you are sending a newsletter or offers to customers, for instance, your emails will always reach their target audience, whereas unauthorized third parties will not be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated service come with DKIM activated by default, so in case you choose a semi-dedicated package and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private cryptographic key on our email servers for the electronic signature and a TXT record carrying the public key for the DNS system. Since the protection is set up for a specific domain, all email addresses created under it will carry a signature, so you won’t have to worry that the messages that you send may not be delivered to their destination address or that somebody may spoof any of your addresses and try to spam/scam people. This may be rather important when you rely on e-communication in your business, since your associates and/or clients will be able to distinguish real messages from forged ones.
