DomainKeys Identified Mail (DKIM) is an authentication system used to verify that an e-mail message has been sent by an authenticated email server or individual. An electronic signature is attached to the header of the email using a private encryption key. When the message is received, a public key that’s available in the global Domain Name System is used to confirm who actually sent it and whether its content has been changed in any way. The principal purpose of DomainKeys Identified Mail is to prevent 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 doesn’t correspond, you will either not receive the message at all, or you’ll receive it with a warning note that most probably it’s not genuine. It depends on mail service providers what exactly will happen with an email which fails the signature test. DomainKeys Identified Mail will also offer you an additional protection layer when you communicate with your business partners, for instance, as they can see that all the messages that you send are legitimate and haven’t been manipulated in the meantime.
DomainKeys Identified Mail in Website Hosting
If you host a domain in a website hosting account with our company, all the necessary records for using the DomainKeys Identified Mail functionality will be set up by default. This will happen once you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, on the condition that it also uses our NS resource records. A private cryptographic key will be generated on our email servers, whereas a public key will be published to the DNS database automatically using the TXT record. In this way, you won’t need to do anything manually and you’ll be able to take advantage of all the benefits of this authentication system – your email messages will be delivered to any target destination without being discarded and no one will be able to send out emails faking your e-mail addresses. The latter is pretty important if the nature of your Internet presence involves sending out regular offers or newsletters via email to potential and existing clients.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our Linux semi-dedicated packages come with DKIM enabled by default, so if you select a semi-dedicated server package and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the email validation system will be created automatically – a private cryptographic key on our email servers for the digital signature and a TXT resource record carrying the public key for the DNS database. As the DKIM protection is set up for a given domain name, all addresses created under it will have a signature, so you will not need to worry that the emails that you send out may not be delivered to their target address or that someone may forge any of your addresses and try to scam/spam people. This may be very important in case you rely on email communication in your business, as your partners and/or clients will be able to distinguish real email messages from false ones.
