DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email message by using an e-signature. When DomainKeys Identified Mail is activated for a given domain, a public cryptographic key is published to the global DNS system and a private one is kept on the mail server. When a new email message is sent, a signature is issued using the private key and when the email is delivered, that signature is authenticated by the incoming POP3/IMAP server using the public key. Thus, the receiver can easily discern if the message is authentic or if the sender’s email address has been forged. A mismatch will appear if the content of the email has been edited in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered emails are identical and that nothing has been attached or erased. This email authentication system will increase your email security, since you can verify the legitimacy of the important email messages that you receive and your colleagues can do likewise with the messages that you send them. Depending on the given mail service provider’s policies, a message that fails to pass the test may be erased or may enter the recipient’s mailbox with a warning sign.
DomainKeys Identified Mail in Shared Hosting
When you purchase one of the shared hosting service that we offer, the DomainKeys Identified Mail option will be activated by default for any domain that you register under your account, so you won’t need to create any records or to activate anything manually. When a domain is added in the Hosted Domains section of our in-house developed 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 encryption key will be issued momentarily on our mail servers and a TXT record with a public key will be sent to the global Domain Name System. All email addresses set up with this domain name will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target audience and the receivers will know that they are genuine, because the DomainKeys Identified Mail option makes it impossible for unauthorized individuals to forge your e-mail addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
The DomainKeys Identified Mail protection service is included by default with any domain name that’s registered through a semi-dedicated server account with our company. The domain must also use our name servers, so that its DNS records are handled by our system. The latter makes it possible for a special TXT resource record to be created, which is actually the public encryption key that confirms if a given email message is authentic or not. Such a record is set up as soon as a new domain name 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 email and web hosting services, your email messages will always reach their target readers and you won’t have to worry about unauthorized people forging your email addresses for spamming or scamming purposes, which is something pretty important if you use email messages to communicate with your business associates.
