DomainKeys Identified Mail (DKIM) is an email authentication system used to prove that an e-mail message has been sent by an authenticated mail server or person. An electronic signature is attached to the header of the email using a private encryption key. When the email message is received, a public key that is available in the global Domain Name System is used to verify who exactly sent it and if its content has been edited in some way. The fundamental job of DKIM is to obstruct the widely spread spam and scam emails, 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 or financial institution, for instance, but the signature doesn’t correspond, you will either not get the email message at all, or you will receive it with a warning alert that most likely it’s not authentic. It depends on mail service providers what exactly will happen with an email message which fails the signature examination. DKIM will also give you an additional security layer when you communicate with your business allies, for example, as they can see that all the e-mails that you exchange are authentic and haven’t been manipulated in the meantime.
DomainKeys Identified Mail in Shared Web Hosting
When you obtain one of the Linux shared web hosting services that we offer, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you add to your website hosting account, so you won’t have to create any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our NS and MX resource records (so that the emails associated with this domain name will be handled by our cloud platform), a private cryptographic key will be generated momentarily on our email servers and a TXT record with a public key will be sent to the DNS system. All addresses created with this domain will be protected by DKIM, so if you send out emails such as regular newsletters, they will reach their target audience and the receivers will be sure that they are genuine, since the DKIM feature makes it impossible for unauthorized individuals to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our Linux semi-dedicated hosting services come with DKIM activated by default, so in case you opt for a semi-dedicated hosting plan and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the email validation 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 DNS system. As the protection is set up for a certain domain, all email addresses created using it will have a signature, so you won’t need to worry that the messages that you send out may not reach their target email address or that somebody may fake any of your addresses and attempt to spam/scam people. This may be very essential if you rely on electronic communication in your business, as your colleagues and/or customers will be able to distinguish real emails from bogus ones.
