DomainKeys Identified Mail (DKIM) is an email validation system used to check that an email has been sent by an authenticated mail server or person. An e-signature is added to the header of the email message using a private key. When the message is received, a public key that is available in the global DNS database is used to validate who exactly sent it and whether its content has been changed in any way. The primary function of DKIM is to prevent the widely spread scam and spam email messages, 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 receive the email message at all, or you will get it with an alert that most likely it’s not genuine. It depends on mail service providers what exactly will happen with an email message which fails to pass the signature check. DomainKeys Identified Mail will also offer you an extra layer of security when you communicate with your business allies, for instance, as they can see for themselves that all the messages that you exchange are legitimate and have not been manipulated on their way.
DomainKeys Identified Mail in Web Hosting
In case you host a domain in a web hosting account from our company, all the obligatory records for using the DomainKeys Identified Mail functionality will be created by default. This will happen as soon as you add the domain name in the Hosted Domains section of the Hepsia Control Panel, as long as it also uses our NS resource records. A private cryptographic key will be generated on our email servers, while a public key will be added to the global Domain Name System automatically using the TXT resource record. Thus, you will not have to do anything manually and you will be able to take full advantage of all the benefits of this email validation system – your messages will reach any destination without being rejected and nobody will be able to send email messages faking your email addresses. The latter is really important if the nature of your Internet presence suggests sending out periodic newsletters or offers via email to potential and current customers.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers come with DKIM enabled by default, so in case you choose a semi-dedicated hosting plan and you add a domain using our name servers via your Hepsia Control Panel, the records required for the email authentication system will be created automatically – a private encryption key on our mail servers for the e-signature and a TXT record carrying the public key for the global DNS system. As the protection is set up for a specific domain name, all email addresses created with it will have a signature, so you will not have to worry that the messages that you send out may not be delivered to their target email address or that somebody may forge any of your addresses and try to spam/scam people. This may be extremely essential in case you rely on electronic communication in your business, as your partners and/or clients will be able to distinguish authentic messages from counterfeit ones.
