DomainKeys Identified Mail (DKIM) is an email authentication system used to prove that an email has been sent by an authenticated mail server or person. An e-signature is attached to the message’s header using a private encryption key. When the email message is received, a public key that’s available in the global DNS database is used to validate who exactly sent it and if its content has been changed in any way. The prime job of DKIM is to block the widespread scam and spam messages, as it makes it impossible to fake an email address. If an email is sent from an address claiming to belong to your bank or financial institution, for example, but the signature does not match, you will either not receive the email at all, or you’ll get it with a warning that most probably it’s not a genuine one. It depends on email service providers what exactly will happen with an email message that fails to pass the signature check. DomainKeys Identified Mail will also offer you an additional layer of safety when you communicate with your business allies, for example, since they can see that all the e-mails that you send are authentic and have not been manipulated on their way.
DomainKeys Identified Mail in Cloud Hosting
In case you host a domain in a cloud hosting account with our company, all the obligatory records for using the DomainKeys Identified Mail feature will be added by default. This will happen once you add the domain in the Control Panel’s Hosted Domains section, on the condition that your domain also uses our NS resource records. A private encryption key will be created on our email servers, whereas a public key will be published to the global DNS system automatically using the TXT resource record. In this way, you will not have to do anything manually and you’ll be able to enjoy all the benefits of this validation system – your messages will be delivered to any destination without being disallowed and no one will be able to send out emails faking your e-mail addresses. The latter is really important if the type of your web presence involves sending regular offers or newsletters via email to prospective and existing customers.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our semi-dedicated services come with DKIM activated by default, so in case you choose a semi-dedicated plan and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private cryptographic key on our mail servers for the electronic signature and a TXT record carrying the public key for the global Domain Name System. Since the protection is set up for a given domain name, all addresses created with it will carry a signature, so you will not have to worry that the emails that you send may not reach their destination address or that somebody may fake any of your email addresses and try to scam/spam people. This may be extremely important when you use electronic communication in your business, since your colleagues and/or customers will be able to distinguish legitimate messages from fake ones.
