DomainKeys Identified Mail (DKIM) is an email validation system used to confirm that an e-mail message has been sent by an authenticated server or individual. An e-signature is attached to the message’s header by using a private key. When the message is received, a public key that’s available in the global Domain Name System is used to verify who exactly sent it and if the content has been modified in any way. The chief task of DKIM is to hinder the widespread spam and scam emails, 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 correspond, you will either not get the email at all, or you will receive it with a notification that most likely it is not a legitimate one. It depends on mail service providers what exactly will happen with an email which fails to pass the signature examination. DKIM will also provide you with an added layer of safety when you communicate with your business associates, for instance, since they can see that all the email messages that you send are authentic and have not been modified on their way.
DomainKeys Identified Mail in Shared Web Hosting
When you obtain any of the shared web hosting service
that we offer, the DomainKeys Identified Mail feature will be activated by default for any domain name that you register under your shared account, so you won’t have to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our MX and NS records (so that the emails related to this domain name will be handled by our cloud hosting platform), a private cryptographic key will be generated straight away on our mail servers and a TXT resource record with a public key will be sent to the DNS system. All email addresses set up with this domain name 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 receivers will know that the messages are legitimate, because the DomainKeys Identified Mail option makes it impossible for unsolicited persons to forge your email addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
Our Linux semi-dedicated servers
come with DKIM enabled by default, so in case you pick a semi-dedicated plan and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the validation system will be set up automatically – a private encryption key on our mail servers for the e-signature and a TXT record carrying the public key for the Domain Name System. Since the protection is set up for a certain domain, all e-mail addresses created using it will have a signature, so you won’t have to worry that the messages that you send may not reach their destination email address or that somebody may forge any of your email addresses and attempt to spam/scam people. This may be quite important in case you rely on email communication in your business, as your associates and/or clients will be able to distinguish authentic emails from false ones.
