DomainKeys Identified Mail, or DKIM, is a system for validating the authenticity of an email using an electronic signature. When DomainKeys Identified Mail is activated for a given domain name, a public key is published to the global DNS 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 message is received, that signature is authenticated by the POP3/IMAP server using the public key. In this way, the recipient can easily recognize if the message is genuine or if the sender’s address has been spoofed. A discrepancy will appear if the content of the email has been altered on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the delivered messages are identical and that nothing has been added or removed. This validation system will heighten your email security, since you can verify the genuineness of the important email messages that you receive and your associates can do the same with the messages that you send them. Based on the particular email service provider’s policy, a message that fails to pass the test may be removed or may appear in the receiver’s inbox with a warning notification.

DomainKeys Identified Mail in Hosting

The DomainKeys Identified Mail option is pre-activated for all domains that are hosted in a hosting account on our cloud hosting platform, so you won’t need to do anything on your end to activate it. The only requirement is that the particular domain should be hosted in an account on our platform using our MX and NS 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 record, which includes the public key, will be published to the DNS database automatically, so you won’t need to do anything manually on your end in order to enable this option. The DKIM authentication system will allow you to send trustable email messages, so if you’re sending offers or a newsletter to clients, for example, your emails will always reach their target audience, while unsolicited third parties will not be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our semi-dedicated packages come with DomainKeys Identified Mail activated by default, so if you choose a semi-dedicated server package and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the authentication system will be set up automatically – a private cryptographic key on our email servers for the digital signature and a TXT resource record carrying the public key for the global DNS database. As the DKIM protection is set up for a certain domain, all email addresses created using it will carry a signature, so you will not need to worry that the emails that you send out may not reach their target email address or that somebody may spoof any of your email addresses and attempt to scam/spam people. This may be rather important if you rely on electronic communication in your business, as your partners and/or customers will be able to distinguish genuine emails from false ones.
