DomainKeys Identified Mail, or DKIM, is a system for validating the authenticity of an email using a digital signature. When DomainKeys Identified Mail is activated for a particular domain, a public cryptographic key is published to the global Domain Name System and a private one is kept on the email server. If a new email message is sent, a signature is issued using the private key and when the email message is delivered, that signature is validated by the incoming server using the public key. Thus, the recipient can easily discern if the email is authentic or if the sender’s email address has been forged. A mismatch will appear if the content of the email message has been changed in the meantime as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the delivered emails are identical and that nothing has been attached or erased. This validation system will strengthen your email safety, as you can verify the authenticity of the important emails that you get and your colleagues can do the same with the email messages that you send them. Based on the given mail service provider’s policy, an email that fails the test may be removed or may end up in the receiver’s mailbox with a warning notification.

DomainKeys Identified Mail in Shared Web Hosting

If you order one of the Linux shared web hosting services that we offer, the DomainKeys Identified Mail functionality will be activated by default for any domain that you add to your website hosting account, so you won’t have to set up any records or to activate anything manually. When a domain is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our MX and NS records (so that the email messages related to this domain will be handled by our cloud web hosting platform), a private key will be created instantly on our mail servers and a TXT resource record with a public key will be sent to the global DNS system. All email addresses created with this domain name will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target destination and the recipients will know that they are genuine, because the DomainKeys Identified Mail option makes it impossible for unsolicited persons to forge your addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our semi-dedicated hosting services come with DKIM activated by default, so in case you opt for a semi-dedicated server plan and you add a domain using our name servers via your Hepsia Control Panel, the records required for the authentication system will be created automatically – a private cryptographic key on our mail servers for the electronic signature and a TXT record carrying the public key for the Domain Name System. As the protection is set up for a particular domain name, all email addresses created using it will carry a signature, so you will not need to worry that the email messages that you send out may not be delivered to their destination address or that somebody may fake any of your email addresses and attempt to scam/spam people. This may be rather important when you use e-communication in your business, since your associates and/or customers will be able to distinguish real emails from spoofed ones.
