DomainKeys Identified Mail, or DKIM, is a method for confirming the authenticity of an email using an e-signature. When DKIM is activated for a certain domain name, 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 is sent, a signature is generated using the private key and when the email is delivered, the signature is checked by the incoming POP3/IMAP email server using the public key. In this way, the recipient can easily know if the email is genuine or if the sender’s address has been spoofed. A discrepancy will appear if the content of the email message has been edited in the meantime as well, so DKIM can also be used to make sure that the sent and the received email messages are identical and that nothing has been added or erased. This validation system will increase your email security, since you can validate the genuineness of the important email messages that you get and your associates can do the exact same thing with the messages that you send them. Depending on the given email service provider’s adopted policy, an email message that fails the examination may be removed or may enter the recipient’s mailbox with a warning notification.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail option is enabled by default for all domain names that are hosted in a shared hosting account on our cloud hosting platform, so you will not need to do anything on your end to turn it on. The only requirement is that the particular domain name should be hosted in an account on our platform using our NS and MX resource records, so that the e-mails will go through our mail servers. The private key will be generated on the server and the TXT resource record, which includes the public key, will be published to the DNS system automatically, so you will not need to do anything manually on your end in order to activate this feature. The DKIM email validation system will permit you to send out credible messages, so if you’re sending offers or a newsletter to customers, for example, 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 Hosting

Our Linux semi-dedicated packages come with DKIM enabled by default, so if you choose a semi-dedicated hosting plan and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the authentication system will be set up automatically – a private key on our email servers for the e-signature and a TXT record carrying the public key for the global Domain Name System. Since the DKIM protection is set up for a certain domain, all email addresses created with it will carry a signature, so you won’t need to worry that the emails that you send may not reach their destination email address or that somebody may fake any of your email addresses and attempt to scam/spam people. This may be rather important if you use e-communication in your business, as your associates and/or clients will be able to distinguish real messages from false ones.
