DomainKeys Identified Mail (DKIM) is a validation system used to certify that an email has been sent by an authorized person or mail server. A digital signature is added to the header of the email message using a private encryption key. When the email message is received, a public key that is available in the global DNS database is used to verify who exactly sent it and whether the content has been modified in any way. The main purpose of DomainKeys Identified Mail is to hinder the widespread spam and scam 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 or financial institution, for instance, but the signature does not correspond, you will either not get the email message at all, or you will receive it with a warning alert that most likely it is not a legitimate one. It depends on email providers what exactly will happen with an email which fails to pass the signature check. DomainKeys Identified Mail will also offer you an added layer of protection when you communicate with your business associates, for example, since they can see for themselves that all the emails that you send are legitimate and haven’t been tampered with in the meantime.
DomainKeys Identified Mail in Cloud Hosting
If you host a domain in a cloud hosting
account from us, 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 Control Panel, on the condition that your domain also uses our NS resource records. A private encryption key will be generated on our email servers, whereas a public key will be sent to the global DNS system automatically using the TXT resource record. In this way, you will not need to do anything manually and you’ll be able to take full advantage of all the benefits of this authentication system – your messages will be delivered to any target destination without being denied and no one will be able to send email messages forging your addresses. The latter is quite important if the type of your online presence involves sending periodic newsletters or offers via email to potential and existing customers.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers
come with DKIM activated by default, so in case you choose a semi-dedicated hosting plan and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the email authentication system will be created automatically – a private cryptographic key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the Domain Name System. As the protection is set up for a specific domain name, all e-mail addresses created with 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 destination address or that someone may fake any of your email addresses and try to scam/spam people. This may be extremely important in case you use email communication in your business, as your colleagues and/or customers will be able to distinguish real emails from fake ones.
