DomainKeys Identified Mail, or DKIM, is a system for validating the legitimacy of an email message by using an e-signature. When DKIM is enabled for a given domain, a public cryptographic key is published to the global DNS system and a private one is stored on the email server. If a new message is sent, a signature is generated using the private key and when the message is received, the signature is checked by the incoming POP3/IMAP email server using the public key. In this way, the receiver can easily recognize if the message is authentic or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email message has been edited in the meantime as well, so DKIM can also be used to make sure that the sent and the received messages are identical and that nothing has been attached or erased. This email authentication system will strengthen your email security, since you can verify the legitimacy of the important email messages that you get and your associates can do likewise with the messages that you send them. Based on the given mail service provider’s policies, an email that fails to pass the test may be removed or may emerge in the receiver’s mailbox with a warning symbol.
DomainKeys Identified Mail in Shared Website Hosting
The DomainKeys Identified Mail option is pre-enabled for all domain names that are hosted in a shared website hosting account on our cloud website hosting platform, so you won’t have to do anything yourself to enable it. The sole requirement is that the given domain name should be hosted in an account on our platform using our NS and MX records, so that the email messages will go through our email servers. The private cryptographic key will be created on the server and the TXT resource record, which contains the public key, will be published to the DNS system automatically, so you will not have to do anything manually on your end in order to enable this option. The DomainKeys Identified Mail authentication system will allow you to send out trustable e-mail messages, so if you’re sending a newsletter or offers to customers, for instance, your email messages will always reach their target destination, whereas unauthorized 3rd parties will not be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our semi-dedicated hosting come with DomainKeys Identified Mail enabled by default, so in case you select a semi-dedicated plan and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the validation system will be set up automatically – a private cryptographic key on our mail servers for the digital signature and a TXT resource record carrying the public key for the global DNS system. As the DKIM protection is set up for a particular domain, all e-mail addresses created using it will have a signature, so you won’t have to worry that the emails that you send may not reach their destination address or that somebody may forge any of your email addresses and attempt to spam/scam people. This may be very essential when you rely on email communication in your business, as your associates and/or customers will be able to distinguish legitimate email messages from counterfeit ones.
