DomainKeys Identified Mail, or DKIM, is a method for verifying the authenticity of an email by using an e-signature. When DKIM is activated for a specific domain name, a public encryption key is published to the global Domain Name System and a private one is kept on the email server. If a new email message is sent, a signature is generated using the private key and when the email is delivered, that signature is checked by the incoming POP3/IMAP email server using the public key. In this way, the recipient can easily distinguish if the email message is genuine or if the sender’s email address has been spoofed. A discrepancy will appear 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 delivered emails are identical and that nothing has been attached or erased. This email authentication system will heighten your email security, since you can validate the legitimacy of the important emails that you get and your partners can do the exact same thing with the emails that you send them. Based on the particular mail service provider’s policies, an email message that fails to pass the test may be erased or may reach the recipient’s inbox with a warning notification.
DomainKeys Identified Mail in Shared Hosting
In case you host a domain in a shared hosting account with our company, all the needed records for using the DomainKeys Identified Mail option will be added by default. This will happen once you add the domain in the Control Panel’s Hosted Domains section, as long as the domain also uses our NS resource records. A private key will be created on our email servers, whereas a public key will be added to the DNS database automatically by using the TXT resource record. Thus, you won’t need to do anything manually and you’ll be able to make use of all the benefits of this authentication system – your messages will be sent to any destination without being discarded and no one will be able to send out email messages forging your e-mail addresses. The latter is rather important if the type of your online presence suggests sending out periodic offers or newsletters via email to potential and current customers.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated plans come with DomainKeys Identified Mail enabled by default, so if you opt for this type of hosting and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the email validation system will be set up automatically – a private key on our mail servers for the digital signature and a TXT record carrying the public key for the global DNS system. As the DKIM protection is set up for a certain domain, all email addresses created with it will have a signature, so you will not need to worry that the email messages that you send out may not be delivered to their target email address or that somebody may fake any of your addresses and try to scam/spam people. This may be rather important when you rely on email communication in your business, since your colleagues and/or clients will be able to distinguish real emails from counterfeit ones.
