DomainKeys Identified Mail, or DKIM, is a system for checking the legitimacy of an email message using a digital signature. When DKIM is activated for a given domain name, a public cryptographic key is published to the global DNS system and a private one is stored on the email server. When a new email is sent, a signature is generated using the private key and when the email message is delivered, the signature is checked by the POP3/IMAP mail server using the public key. Thus, the receiver can easily know if the email message is authentic or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email message has been altered in the meantime as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received emails are identical and that nothing has been attached or erased. This email validation system will increase your email security, as you can validate the genuineness of the important email messages that you get and your partners can do likewise with the emails that you send them. Depending on the particular email provider’s policies, an email that fails to pass the check may be removed or may enter the receiver’s inbox with a warning sign.

DomainKeys Identified Mail in Shared Hosting

If you obtain any of the Linux shared hosting plans that we offer, the DomainKeys Identified Mail option will be activated as standard for any domain that you register under your shared account, so you won’t need to set up any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our NS and MX records (so that the emails associated with this domain name will be handled by our cloud hosting platform), a private key will be issued instantly on our mail servers and a TXT record with a public key will be sent to the DNS database. All addresses created using this domain name will be protected by DKIM, so if you send emails such as regular newsletters, they will reach their target audience and the receivers will know that they are authentic, because the DKIM functionality makes it impossible for unauthorized parties to forge your addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

The DomainKeys Identified Mail functionality is offered by default with any domain name that is added to a semi-dedicated server account with us. It should also use our name servers, so that its DNS records are managed by our system. The latter makes it possible for a special TXT record to be set up, which is actually the public encryption key that verifies if a given message is legitimate or not. This record is set up when a domain is added to a semi-dedicated account through the Hepsia Control Panel and in the meantime, a private key is generated on our email servers. If you make use of our web and email hosting services, your email messages will always reach their target readers and you won’t need to worry about unsolicited people forging your email addresses for scamming or spamming purposes, which is something quite important in case you use emails to reach your business collaborators.
