DomainKeys Identified Mail (DKIM) is an email validation system used to prove that an e-mail has been sent by an authenticated email server or individual. An electronic signature is attached to the header of the email by using a private cryptographic key. When the email is received, a public key that is available in the global DNS database is used to check who exactly sent it and whether the content has been edited in any way. The principal function of DomainKeys Identified Mail is to hamper the widely spread scam and spam messages, as it makes it impossible to fake an email address. If a message 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 email at all, or you will get it with an alert that most probably it’s not legitimate. It depends on email providers what exactly will happen with an email message which fails to pass the signature test. DomainKeys Identified Mail will also give you an additional layer of security when you communicate with your business partners, for instance, since they can see that all the e-mails that you send are legitimate and haven’t been tampered with on their way.
DomainKeys Identified Mail in Website Hosting
In case you host a domain name in a website hosting account from our company, all the needed records for using the DomainKeys Identified Mail feature will be added by default. This will happen once you add the domain name in the Hosted Domains section of the Hepsia Control Panel, provided that your domain also uses our NS resource records. A private cryptographic key will be generated on our mail servers, whereas a public key will be sent to the DNS system automatically using the TXT resource record. Thus, you won’t need to do anything manually and you will be able to take full advantage of all the benefits of this email validation system – your emails will reach any audience without being denied and no one will be able to send out email messages faking your e-mail addresses. The latter is quite important if the essence of your online presence involves sending regular offers or newsletters via email to potential and existing customers.
DomainKeys Identified Mail in Semi-dedicated Hosting
All required DomainKeys Identified Mail records will be set up automatically by our cloud platform when you add a domain as hosted in a semi-dedicated server account, so in case you choose to order a semi-dedicated plan, you will not need to set up anything to be able to use the email validation system. The domain name must use our name servers in order for its DNS records to be managed by us and as long as this prerequisite is fulfilled, a private cryptographic key will be created on our mail servers and a public key will be sent to the global Domain Name System by a special TXT resource record. All addresses that you create with the domain will be protected by DomainKeys Identified Mail, which will make it impossible for 3rd parties to fake any email address. Both you and your partners or clients can take advantage of this option, since it will ensure a higher security level for your online correspondence.
