DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email using a digital signature. When DomainKeys Identified Mail is activated for a given domain, 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 message is received, the signature is validated by the incoming mail server using the public key. In this way, the recipient can easily tell if the email message is genuine or if the sender’s address has been forged. A discrepancy will occur if the content of the email has been altered in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered emails are identical and that nothing has been attached or removed. This validation system will enhance your email safety, since you can validate the legitimacy of the important email messages that you receive and your colleagues can do the exact same thing with the email messages that you send them. Depending on the particular mail service provider’s policy, a message that fails the check may be removed or may reach the recipient’s mailbox with a warning flag.
DomainKeys Identified Mail in Cloud Hosting
The DomainKeys Identified Mail functionality is enabled by default for all domain names that are hosted in a cloud hosting account on our cloud hosting platform, so you won’t have to do anything on your end to enable it. The sole requirement is that the particular domain should be hosted in an account on our platform using our MX and NS resource records, so that the email messages will go through our mail servers. The private cryptographic key will be generated on the server and the TXT record, which contains the public key, will be published to the Domain Name System automatically, so you will not have to do anything manually on your end in order to activate this option. The DKIM email authentication system will permit you to send out credible email messages, so if you are sending a newsletter or offers to clients, for example, 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 Servers
Our semi-dedicated servers 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 through your Hepsia Control Panel, the records needed for the authentication system will be set up automatically – a private encryption key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the DNS database. Since the DKIM protection is set up for a specific domain, all e-mail addresses created under it will carry a signature, so you will not have to worry that the messages that you send may not be delivered to their target email address or that someone may fake any of your addresses and attempt to spam/scam people. This may be very important in case you rely on email communication in your business, since your associates and/or customers will be able to distinguish authentic messages from forged ones.
