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 email message’s header by using a private cryptographic key. When the email message is received, a public key that’s available in the global DNS database is used to verify who exactly sent it and if its content has been changed in any way. The fundamental job of DomainKeys Identified Mail is to block the widespread scam and spam messages, as it makes it impossible to forge an email address. If an email message is sent from an email address claiming to belong to your bank, for instance, but the signature does not match, you will either not get the email at all, or you will get it with a warning notice that most probably it is not genuine. It depends on mail service providers what exactly will happen with an email message which fails the signature check. DKIM will also give you an added protection layer when you communicate with your business allies, for example, as they can see that all the email messages that you send are legitimate and have not been modified on their way.

DomainKeys Identified Mail in Shared Hosting

You’ll be able to make use of DomainKeys Identified Mail with each and every Linux shared hosting plans that we’re offering without needing to do anything specific, as the mandatory records for using this authentication system are set up automatically by our web hosting platform when you add a domain name to an existing account using the Hepsia Control Panel. As long as the given domain uses our name server records, a private key will be generated and stored on our email servers and a TXT resource record with a public key will be sent to the DNS system. If you send out regular email messages to customers or business partners, they will always be delivered and no unauthorized individual will be able to forge your address and make it seem like you’ve composed a particular email message.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated plans come with DomainKeys Identified Mail enabled by default, so if you choose a semi-dedicated plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the authentication system will be set up automatically – a private key on our email servers for the e-signature and a TXT resource record carrying the public key for the DNS database. Since the protection is set up for a specific domain, all email addresses created with it will carry a signature, so you will not need to worry that the email messages that you send may not be delivered to their destination address or that someone may spoof any of your email addresses and try to scam/spam people. This may be very essential if you rely on email communication in your business, since your associates and/or clients will be able to distinguish legitimate emails from phony ones.
