DomainKeys Identified Mail, or DKIM, is a system for validating the genuineness of an email by using a digital signature. When DomainKeys Identified Mail is activated for a given domain name, a public encryption key is published to the global DNS database and a private one is stored on the mail server. If a new message is sent, a signature is generated using the private key and when the email is delivered, that signature is verified by the incoming server using the public key. In this way, the receiver can easily recognize if the email message is genuine or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email 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 removed. This email validation system will boost your email safety, since you can verify the legitimacy of the important emails that you receive and your partners can do the exact same thing with the email messages that you send them. Depending on the given mail service provider’s policy, a message that fails to pass the check may be removed or may emerge in the receiver’s inbox with a warning sign.

DomainKeys Identified Mail in Shared Web Hosting

If you host a domain name in a shared web hosting account from our company, all the compulsory records for using the DomainKeys Identified Mail functionality will be created by default. This will happen the moment you add the domain in the Control Panel’s Hosted Domains section, provided that it also uses our NS resource records. A private cryptographic key will be generated on our email servers, whereas a public key will be sent to the global DNS system automatically by using the TXT resource record. In this way, you will not need to do anything manually and you’ll be able to take full advantage of all the benefits of this authentication system – your messages will be delivered to any target destination without being disallowed and nobody will be able to send out messages forging your e-mail addresses. The latter is pretty important in case the type of your online presence suggests sending out regular offers or newsletters via email to prospective and current clients.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated hosting plans come with DomainKeys Identified Mail enabled by default, so in case you select a semi-dedicated server package 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 email servers for the digital signature and a TXT resource record carrying the public key for the Domain Name System. As the protection is set up for a given domain, all email addresses created using it will carry a signature, so you will not need to worry that the messages that you send may not be delivered to their destination email address or that somebody may spoof any of your addresses and try to spam/scam people. This may be very important in case you rely on email communication in your business, as your colleagues and/or clients will be able to distinguish legitimate messages from spoofed ones.
