DomainKeys Identified Mail (DKIM) is an email validation system used to confirm that an email message has been sent by an authorized email server or individual. A digital signature is attached to the message’s header by using a private cryptographic key. When the message is received, a public key that’s available in the global Domain Name System is used to confirm who exactly sent it and whether its content has been modified in any way. The chief purpose of DKIM is to impede the widespread spam and scam email messages, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank, for instance, but the signature does not match, you will either not get the message at all, or you will receive it with a notification that most likely it’s not genuine. It depends on email providers what exactly will happen with an email message that fails to pass the signature test. DomainKeys Identified Mail will also supply you with an additional protection layer when you communicate with your business allies, for example, since they can see that all the email messages that you send are legitimate and have not been modified on their way.
DomainKeys Identified Mail in Shared Website Hosting
In case you host a domain name in a shared website hosting account from us, all the needed records for using the DomainKeys Identified Mail feature will be set up by default. This will happen the moment you add the domain in , provided that the domain also uses our NS resource records. A private key will be created on our mail servers, whereas a public key will be sent to the global Domain Name System automatically using the TXT resource record. Thus, you will not need to do anything manually and you will be able to take full advantage of all the benefits of this email validation system – your messages will be sent to any destination without being disallowed and nobody will be able to send email messages faking your addresses. The latter is very important in case the type of your worldwide web presence involves sending out regular offers or newsletters via email to potential and current customers.
