DomainKeys Identified Mail (DKIM) is an email validation system used to prove that an email has been sent by an authorized individual or email server. An electronic signature is added 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 DNS database is used to validate who actually sent it and if the content has been modified in any way. The principal job of DomainKeys Identified Mail is to hamper the widespread scam and spam messages, as it makes it impossible to forge an email address. If an email is sent from an email address claiming to belong to your bank or financial institution, for instance, but the signature does not correspond, you will either not receive the email at all, or you’ll receive it with a warning that most probably it’s not a genuine one. It depends on email providers what exactly will happen with an email which fails to pass the signature test. DKIM will also offer you an added layer of safety when you communicate with your business partners, for example, since they can see for themselves that all the emails that you send are genuine and haven’t been modified on their way.
DomainKeys Identified Mail in Shared Hosting
If you host a domain in a shared hosting
account with our company, all the necessary records for using the DomainKeys Identified Mail feature will be added by default. This will happen as soon as you add the domain name in , on the condition that your domain also uses our NS records. A private encryption key will be created on our email servers, whereas a public key will be sent to the DNS database automatically using the TXT resource record. Thus, you will not have to do anything manually and you will be able to make use of all the benefits of this authentication system – your emails will reach any audience without being discarded and no one will be able to send emails forging your email addresses. The latter is truly important in case the nature of your online presence suggests sending out periodic newsletters or offers via email to prospective and current customers.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers
come with DomainKeys Identified Mail activated by default, so if you choose a semi-dedicated plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the validation system will be created automatically – a private cryptographic key on our email servers for the e-signature and a TXT record carrying the public key for the global DNS database. Since the protection is set up for a certain domain, all addresses created using it will carry a signature, so you won’t need to worry that the email messages that you send may not reach their target email address or that someone may fake any of your addresses and try to spam/scam people. This may be very important in case you rely on electronic communication in your business, since your colleagues and/or customers will be able to distinguish real email messages from forged ones.
