DomainKeys Identified Mail (DKIM) is an authentication system used to check that an e-mail has been sent by an authorized individual or email server. An e-signature is added to the email message’s header using a private encryption key. When the email message is received, a public key that is available in the global DNS database is used to check who exactly sent it and whether its content has been altered in any way. The fundamental job of DKIM is to obstruct the widespread scam and spam 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 example, but the signature does not match, you will either not receive the email at all, or you will get it with a warning notification that most probably it is not a genuine one. It depends on email service providers what exactly will happen with an email message that fails the signature check. DomainKeys Identified Mail will also offer you an extra security layer when you communicate with your business associates, for example, since they can see that all the emails that you send are genuine and have not been modified in the meantime.

DomainKeys Identified Mail in Web Hosting

When you obtain any of the Linux web hosting packages that we’re offering, the DomainKeys Identified Mail feature will be activated by default for any domain that you register under your shared account, so you won’t have to set up any records or to do anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain name will be handled by our cloud platform), a private key will be created immediately on our email servers and a TXT resource record with a public key will be sent to the DNS system. All email addresses created with this domain will be protected by DKIM, so if you send emails such as regular newsletters, they will reach their target destination and the recipients will be sure that they are genuine, because the DKIM option makes it impossible for unsolicited people to forge your e-mail addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated packages come with DKIM enabled by default, so if you select this type of hosting and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the authentication system will be created automatically – a private encryption key on our mail servers for the digital signature and a TXT resource record carrying the public key for the global DNS database. As the DKIM protection is set up for a specific domain, all addresses created with it will have a signature, so you will not have to worry that the email messages that you send out may not reach their destination email address or that someone may forge any of your addresses and attempt to spam/scam people. This may be rather important when you rely on electronic communication in your business, as your associates and/or clients will be able to distinguish legitimate messages from false ones.
