DomainKeys Identified Mail (DKIM) is a validation system used to certify that an email has been sent by an authorized server or person. An e-signature is attached to the header of the email by using a private key. When the message is received, a public key that’s available in the global DNS database is used to verify who actually sent it and if its content has been altered in some way. The primary task of DomainKeys Identified Mail is to obstruct the widely spread spam and scam email messages, as it makes it impossible to forge an email address. If an email is sent from an address claiming to belong to your bank, for instance, but the signature doesn’t match, you will either not get the email at all, or you will receive it with an alert that most likely it’s not legitimate. It depends on email service providers what exactly will happen with an email which fails the signature check. DKIM will also supply you with an additional security layer when you communicate with your business associates, for example, since they can see that all the email messages that you send are genuine and haven’t been manipulated on their way.
DomainKeys Identified Mail in Cloud Hosting
If you order one of the Linux cloud hosting plans that we offer, the DomainKeys Identified Mail feature will be activated by default for any domain that you register under your account, so you will not need to set up any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain will be handled by our cloud platform), a private key will be created straight away on our email servers and a TXT record with a public key will be sent to the global DNS database. All addresses set up with this domain will be protected by DomainKeys Identified Mail, so if you send out emails such as regular newsletters, they will reach their target audience and the recipients will be sure that the messages are legitimate, since the DKIM option makes it impossible for unsolicited individuals to forge your addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
Our Linux semi-dedicated servers come with DKIM enabled by default, so if you select a semi-dedicated server plan and you add a domain using our name servers via your Hepsia Control Panel, the records required for the authentication system will be created automatically – a private cryptographic key on our email servers for the electronic signature and a TXT record carrying the public key for the global DNS system. As the DKIM protection is set up for a particular domain, all addresses created using it will carry a signature, so you won’t have to worry that the emails that you send out may not reach their destination email address or that somebody may fake any of your addresses and attempt to spam/scam people. This may be quite important when you rely on email communication in your business, since your colleagues and/or customers will be able to distinguish legitimate email messages from counterfeit ones.
