DomainKeys Identified Mail, or DKIM, is a method for checking the authenticity of an email message by using a digital signature. When DomainKeys Identified Mail is enabled for a certain domain name, a public key is published to the global DNS database and a private one is stored on the mail server. When a new message is sent, a signature is issued using the private key and when the email is received, the signature is verified by the POP3/IMAP server using the public key. In this way, the recipient can easily know if the email is legitimate or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email has been modified on its way 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 added or deleted. This validation system will enhance your email safety, since you can validate the legitimacy of the important email messages that you receive and your associates can do likewise with the messages that you send them. Based on the given email service provider’s policy, an email that fails to pass the check may be erased or may appear in the receiver’s mailbox with a warning sign.

DomainKeys Identified Mail in Hosting

In case you host a domain name in a hosting account from our company, all the required records for using the DomainKeys Identified Mail option will be set up by default. This will happen once you add the domain in the Hosted Domains section of the Hepsia Control Panel, on the condition that your domain also uses our NS resource records. A private encryption key will be generated on our mail servers, while a public key will be sent to the DNS database automatically using the TXT resource record. In this way, you won’t have to do anything manually and you’ll be able to take advantage of all the benefits of this email authentication system – your emails will be delivered to any target destination without being rejected and nobody will be able to send email messages faking your e-mail addresses. The latter is truly important in case the type of your web presence suggests sending out periodic newsletters or offers via email to prospective and current customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting packages come with DomainKeys Identified Mail activated by default, so in case you pick 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 email validation system will be created automatically – a private cryptographic key on our email servers for the e-signature and a TXT record carrying the public key for the global DNS database. Since the protection is set up for a particular domain, all addresses created using it will carry a signature, so you won’t need to worry that the email messages that you send out may not be delivered to their destination email address or that somebody may forge any of your email addresses and attempt to spam/scam people. This may be very important when you rely on electronic communication in your business, as your partners and/or clients will be able to distinguish real emails from forged ones.
