DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an email has been sent by an authorized person or mail server. An electronic signature is attached to the header of the email message using a private cryptographic key. When the message is received, a public key that is available in the global DNS database is used to check who exactly sent it and if the content has been altered in any way. The principal task of DKIM is to hinder the widespread scam and spam messages, as it makes it impossible to fake an email address. If an email message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature does not correspond, you will either not receive the email at all, or you will get it with an alert that most likely it is not legitimate. It depends on email service providers what exactly will happen with an email message which fails the signature test. DKIM will also give you an additional layer of protection when you communicate with your business associates, for example, since they can see that all the e-mail messages that you exchange are legitimate and have not been manipulated in the meantime.
DomainKeys Identified Mail in Web Hosting
You’ll be able to take advantage of DomainKeys Identified Mail with each Linux web hosting
that we offer without doing anything in particular, because the necessary records for using this email validation system are set up automatically by our web hosting platform when you add a domain to an active hosting account using the Hepsia Control Panel. As long as the domain in question uses our name server records, a private encryption key will be issued and stored on our mail servers and a TXT record with a public key will be sent to the DNS system. If you send out periodic messages to customers or business collaborators, they’ll always be received and no unauthorized person will be able to forge your email address and make it look like you’ve sent a certain message.
DomainKeys Identified Mail in Semi-dedicated Servers
Our Linux semi-dedicated hosting plans
come with DKIM enabled by default, so in case you opt for a semi-dedicated plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the email validation system will be set up automatically – a private cryptographic key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the global Domain Name System. Since the DKIM protection is set up for a specific domain name, all addresses created under it will have a signature, so you will not have to worry that the messages that you send out may not reach their target address or that somebody may spoof any of your email addresses and try to scam/spam people. This may be quite important in case you rely on email communication in your business, as your colleagues and/or clients will be able to distinguish legitimate email messages from forged ones.
