DomainKeys Identified Mail (DKIM) is an email validation system used to prove that an e-mail has been sent by an authorized person or mail server. A digital signature is attached to the header of the email message using a private encryption 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 edited in any way. The essential function of DomainKeys Identified Mail is to hinder the widespread spam and scam messages, as it makes it impossible to forge an email address. If a message 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 notice that most probably it’s not authentic. It depends on email service providers what exactly will happen with an email that fails the signature test. DKIM will also give you an additional security layer when you communicate with your business partners, for example, as they can see that all the e-mail messages that you exchange are authentic and have not been manipulated on their way.
DomainKeys Identified Mail in Cloud Hosting
When you purchase one of the Linux cloud hosting plans
that we are offering, the DomainKeys Identified Mail option will be enabled as standard for any domain name that you register under your website hosting account, so you will not need to set up any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our NS and MX records (so that the email messages related to this domain name will be handled by our cloud platform), a private key will be issued right away on our mail servers and a TXT record with a public key will be sent to the DNS system. All email addresses created 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 they are authentic, since the DomainKeys Identified Mail option makes it impossible for unauthorized individuals to forge your email addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated hosting plans
come with DomainKeys Identified Mail activated by default, so if you opt for a semi-dedicated package and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the validation system will be created automatically – a private encryption key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the global Domain Name 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 need to worry that the emails that you send may not be delivered to their target email address or that somebody may forge any of your email addresses and try to spam/scam people. This may be quite essential if you rely on e-communication in your business, as your partners and/or customers will be able to distinguish genuine email messages from counterfeit ones.
