DomainKeys Identified Mail, or DKIM, is a system for confirming the legitimacy of an email message using a digital signature. When DomainKeys Identified Mail is activated for a certain 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 email message is sent, a signature is generated using the private key and when the email message is received, that signature is ‘scanned’ by the incoming POP3/IMAP mail server using the public key. In this way, the receiver can easily discern if the email message is authentic or if the sender’s address has been spoofed. 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 email messages are identical and that nothing has been added or removed. This authentication system will strengthen your email safety, since you can validate the authenticity of the important emails that you receive and your associates can do the exact same thing with the emails that you send them. Depending on the given mail service provider’s policies, an email that fails to pass the check may be deleted or may reach the receiver’s mailbox with a warning.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail option is pre-activated for all domain names that are hosted in a cloud hosting account on our cloud website hosting platform, so you won’t have to do anything yourself to activate it. The sole requirement is that the particular domain should be hosted in a website hosting account on our end using our MX and NS records, so that the email messages will go through our email servers. The private encryption key will be created on the server and the TXT record, which contains the public key, will be published to the DNS database automatically, so you won’t need to do anything manually on your end in order to activate this functionality. The DomainKeys Identified Mail authentication system will enable you to send out trustable e-mails, so if you’re sending a newsletter or offers to customers, for instance, your emails will always reach their target viewers, while unauthorized 3rd parties will not be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so in case you select 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 set up automatically – a private encryption key on our mail servers for the e-signature and a TXT resource record carrying the public key for the global Domain Name System. Since the DKIM protection is set up for a particular domain, all e-mail addresses created using it will carry a signature, so you won’t have to worry that the emails that you send out may not be delivered to their target address or that somebody may spoof any of your email addresses and try to spam/scam people. This may be quite essential in case you use e-communication in your business, since your associates and/or customers will be able to distinguish legitimate messages from spoofed ones.
