DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email message using a digital signature. When DomainKeys Identified Mail is activated for a specific domain, a public cryptographic key is published to the global Domain Name System and a private one is kept on the email server. When a new email is sent, a signature is generated using the private key and when the email is received, the signature is checked by the incoming email server using the public key. In this way, the receiver can easily distinguish if the message is genuine or if the sender’s address has been spoofed. A mismatch will appear 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 added or erased. This authentication system will increase your email security, as you can confirm the legitimacy of the important emails that you receive and your associates can do the exact same thing with the messages that you send them. Depending on the particular email service provider’s policies, a message that fails the test may be deleted or may reach the recipient’s mailbox with a warning.
DomainKeys Identified Mail in Shared Website Hosting
If you purchase one of the Linux shared website hosting that we offer, the DomainKeys Identified Mail feature will be enabled as standard for any domain name that you register under your shard hosting account, so you won’t need to set up any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our NS and MX resource records (so that the emails associated with this domain will be handled by our cloud platform), a private key will be created instantly on our mail servers and a TXT resource record with a public key will be sent to the global DNS system. All addresses set up with this domain will be protected by DomainKeys Identified Mail, so if you send emails such as periodic newsletters, they will reach their target destination and the receivers will be sure that the messages are genuine, because the DomainKeys Identified Mail feature makes it impossible for unauthorized individuals to forge your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
The DomainKeys Identified Mail functionality is included by default with any domain name that’s added to a semi-dedicated server account with our company. It should also use our name servers, so that its DNS records are handled by our platform. The latter makes it possible for a special TXT resource record to be created, which is in fact the public encryption key that verifies if a specific message is genuine or not. Such a record is set up as soon as a new domain is registered in a semi-dedicated server account via the Hepsia Control Panel and at the same time, a private key is created on our email servers. If you use our web and email hosting services, your email messages will always reach their target viewers and you won’t have to worry about unauthorized people using your addresses for scamming or spamming purposes, which is something pretty important when you use emails to touch base with your business partners.
