DomainKeys Identified Mail, or DKIM, is a system for checking the legitimacy of an email message using an electronic signature. When DKIM is activated for a certain domain, a public cryptographic key is published to the global DNS system and a private one is kept on the mail server. When a new email message is sent, a signature is generated using the private key and when the email message is delivered, that signature is ‘scanned’ by the receiving server using the public key. In this way, the recipient can easily discern if the email is legitimate or if the sender’s email address has been spoofed. A discrepancy will appear if the content of the email message has been modified in the meantime 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 added or deleted. This authentication system will heighten your email security, as you can validate the legitimacy of the important email messages that you receive and your partners can do the same with the emails that you send them. Based on the particular email service provider’s adopted policies, a message that fails to pass the test may be deleted or may emerge in the receiver’s inbox with a warning symbol.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail feature is activated by default for all domains that are hosted in a web hosting account on our cloud platform, so you won’t have to do anything yourself to activate it. The only requirement is that the particular domain should be hosted in a web hosting account on our platform using our MX and NS resource records, so that the emails will go through our email servers. The private encryption key will be generated on the server and the TXT record, which includes the public key, will be published to the global DNS database automatically, so you will not need to do anything manually on your end in order to enable this option. The DKIM validation system will allow you to send out trustworthy messages, so if you are sending offers or a newsletter to clients, for instance, your email messages will always reach their target audience, while unauthorized 3rd parties won’t be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated hosting service come with DKIM enabled by default, so in case you pick a semi-dedicated server package and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the email validation system will be set up automatically – a private cryptographic key on our mail servers for the e-signature and a TXT resource record carrying the public key for the Domain Name System. Since the protection is set up for a given domain name, all addresses created using it will have a signature, so you won’t need to worry that the email messages that you send out may not be delivered to their target address or that somebody may spoof any of your addresses and try to scam/spam people. This may be really important if you use electronic communication in your business, since your partners and/or customers will be able to distinguish authentic messages from forged ones.
