DomainKeys Identified Mail, or DKIM, is a system for validating the legitimacy of an email by using an electronic signature. When DomainKeys Identified Mail is activated for a specific domain name, a public cryptographic key is published to the global Domain Name System and a private one is kept on the mail server. If a new email is sent, a signature is generated using the private key and when the email is delivered, that signature is ‘scanned’ by the incoming mail server using the public key. In this way, the receiver can easily distinguish if the email message is authentic or if the sender’s address has been forged. A mismatch will appear 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 delivered email messages are identical and that nothing has been attached or deleted. This email validation system will strengthen your email safety, since you can confirm the legitimacy of the important emails that you receive and your colleagues can do the exact same thing with the messages that you send them. Depending on the particular mail service provider’s policy, an email that fails the examination may be removed or may emerge in the recipient’s inbox with a warning notification.
DomainKeys Identified Mail in Website Hosting
The DomainKeys Identified Mail feature is pre-activated for all domain names that are hosted in a website hosting account on our cloud website hosting platform, so you will not need to do anything yourself to turn it on. The sole requirement is that the given domain name should be hosted in a hosting account on our platform using our NS and MX resource records, so that the e-mail messages will go through our email servers. The private key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global Domain Name System automatically, so you will not have to do anything manually on your end in order to activate this functionality. The DomainKeys Identified Mail email validation system will permit you to send credible email messages, so if you are sending offers or a newsletter to clients, for instance, your emails will always reach their target destination, whereas unsolicited 3rd parties won’t be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our Linux semi-dedicated hosting packages come with DomainKeys Identified Mail enabled by default, so if 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 email validation system will be set up automatically – a private cryptographic key on our email servers for the electronic signature and a TXT resource record carrying the public key for the DNS database. Since the protection is set up for a certain domain name, all email addresses created under it will carry a signature, so you will not need to worry that the emails that you send out may not be delivered to their target address or that somebody may forge any of your email addresses and attempt to spam/scam people. This may be extremely essential if you use email communication in your business, since your colleagues and/or customers will be able to distinguish genuine email messages from counterfeit ones.
