DomainKeys Identified Mail (DKIM) is an email validation system used to check that an email message has been sent by an authenticated individual or server. An electronic signature is attached to the message’s header using a private cryptographic key. When the email is received, a public key that’s available in the global Domain Name System is used to check who actually sent it and if its content has been changed in any way. The main job of DomainKeys Identified Mail is to avert the widely spread scam and spam emails, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank, for example, but the signature does not correspond, you will either not receive the email at all, or you’ll receive it with a warning that most probably it’s not genuine. It depends on email service providers what exactly will happen with an email which fails to pass the signature examination. DKIM will also give you an additional security layer when you communicate with your business partners, for example, since they can see for themselves that all the email messages that you send are legitimate and haven’t been meddled with in the meantime.

DomainKeys Identified Mail in Cloud Web Hosting

If you obtain any of the Linux cloud web hosting packages that we are offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you register under your shard hosting account, so you won’t need to create any records or to do anything manually. When a domain is added in the Hosted Domains section of our in-house built 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 hosting platform), a private cryptographic key will be generated instantaneously on our email servers and a TXT resource record with a public key will be sent to the global DNS database. All email addresses set up using this domain will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target destination and the receivers will know that the messages are genuine, as the DomainKeys Identified Mail option makes it impossible for unauthorized individuals to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting packages come with DKIM enabled by default, so in case you pick a semi-dedicated hosting package and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the validation system will be created automatically – a private key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the global DNS database. Since the DKIM protection is set up for a given domain, all email addresses created with it will carry a signature, so you will not need to worry that the messages that you send may not reach their target address or that someone may fake any of your addresses and attempt to scam/spam people. This may be extremely essential when you rely on email communication in your business, as your colleagues and/or customers will be able to distinguish authentic messages from bogus ones.
