DomainKeys Identified Mail, or DKIM, is a system for validating the authenticity of an email message by using a digital signature. When DKIM is enabled for a particular domain name, a public key is published to the global Domain Name System and a private one is kept on the email server. When a new message is sent, a signature is issued using the private key and when the message is received, the signature is ‘scanned’ by the incoming POP3/IMAP mail server using the public key. In this way, the recipient can easily recognize if the message is authentic or if the sender’s address has been forged. A mismatch will occur if the content of the email has been modified on its way as well, so DKIM can also be used to ensure that the sent and the received messages are identical and that nothing has been attached or removed. This email authentication system will strengthen your email safety, since you can validate the genuineness of the important email messages that you receive and your partners can do the exact same thing with the messages that you send them. Depending on the given mail service provider’s policy, an email message that fails the check may be deleted or may emerge in the receiver’s inbox with a warning alert.

DomainKeys Identified Mail in Cloud Web Hosting

You’ll be able to take full advantage of DomainKeys Identified Mail with each and every Linux cloud web hosting packages that we’re offering without doing anything specific, as the mandatory records for using this authentication system are set up automatically by our web hosting platform when you add a domain to an active hosting account through the Hepsia Control Panel. If the domain name in question uses our name server records, a private cryptographic key will be generated and kept on our email servers and a TXT resource record with a public key will be sent to the global DNS database. If you send out periodic email messages to customers or business allies, they’ll always be delivered and no unauthorized person will be able to spoof your email address and make it look like you have sent a particular email message.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated packages come with DKIM activated by default, so in case you pick a semi-dedicated hosting plan and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the email validation system will be set up automatically – a private key on our mail servers for the e-signature and a TXT resource record carrying the public key for the global DNS system. Since the DKIM protection is set up for a given domain, all e-mail addresses created under it will have a signature, so you won’t need to worry that the email messages that you send may not be delivered to their destination email address or that somebody may forge any of your email addresses and try to scam/spam people. This may be rather essential when you use electronic communication in your business, since your colleagues and/or customers will be able to distinguish real emails from counterfeit ones.
