DomainKeys Identified Mail, or DKIM, is a system for verifying the legitimacy of an email by using an electronic signature. When DomainKeys Identified Mail is enabled for a specific domain name, a public cryptographic key is published to the global DNS system and a private one is kept on the mail server. If a new 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 POP3/IMAP email server using the public key. In this way, the recipient can easily tell if the message is legitimate or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email has been changed on its way as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received messages are identical and that nothing has been attached or removed. This validation system will boost your email safety, since you can validate the legitimacy of the important email messages that you get and your colleagues can do the exact same thing with the emails that you send them. Based on the particular email service provider’s policies, an email message that fails to pass the test may be erased or may enter the recipient’s mailbox with a warning sign.

DomainKeys Identified Mail in Web Hosting

If you host a domain in a web hosting account from us, all the required records for using the DomainKeys Identified Mail functionality will be added by default. This will happen once you add the domain in the Control Panel’s Hosted Domains section, as long as the domain also uses our NS resource records. A private key will be created on our mail servers, while a public key will be sent to the global Domain Name System automatically by using the TXT record. In this way, you won’t need to do anything manually and you’ll be able to enjoy all the benefits of this email authentication system – your emails will reach any target audience without being rejected and nobody will be able to send out emails faking your email addresses. The latter is quite important in case the essence of your Internet presence suggests sending regular offers or newsletters via email to prospective and current customers.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated hosting plans come with DomainKeys Identified Mail enabled by default, so if you opt for a semi-dedicated hosting plan and you add a domain using our name servers via your Hepsia Control Panel, the records required for the email authentication system will be created automatically – a private cryptographic key on our email servers for the electronic signature and a TXT record carrying the public key for the global DNS system. Since the DKIM protection is set up for a given domain, all addresses created with 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 someone may fake any of your addresses and try to spam/scam people. This may be quite essential in case you use e-communication in your business, as your associates and/or customers will be able to distinguish authentic emails from bogus ones.
