DomainKeys Identified Mail (DKIM) is a validation system used to verify that an email message has been sent by an authenticated email server or person. A digital signature is added to the email message’s header by using a private cryptographic key. When the message is received, a public key that is available in the global DNS database is used to confirm who actually sent it and if its content has been modified in any way. The primary job of DomainKeys Identified Mail is to stop the widespread spam and scam 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 or financial institution, for example, but the signature doesn’t match, you will either not get the message at all, or you will get it with a warning that most probably it’s not a genuine one. It depends on mail service providers what exactly will happen with an email that fails to pass the signature check. DomainKeys Identified Mail will also provide you with an added layer of safety when you communicate with your business associates, for example, as they can see for themselves that all the e-mails that you send are authentic and haven’t been tampered with on their way.
DomainKeys Identified Mail in Shared Hosting
In case you host a domain in a shared hosting account from us, all the compulsory records for using the DomainKeys Identified Mail feature will be set up by default. This will happen as soon as you add the domain in , provided that it also uses our NS records. A private key will be created on our mail servers, whereas a public key will be sent to the global DNS database automatically using the TXT record. In this way, you won’t have to do anything manually and you will be able to make use of all the benefits of this email validation system – your email messages will be sent to any target destination without being disallowed and nobody will be able to send emails forging your email addresses. The latter is truly important in case the nature of your web presence suggests sending periodic newsletters or offers via email to potential and current clients.
