DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email by using an electronic signature. When DomainKeys Identified Mail is activated for a certain domain, a public encryption key is published to the global Domain Name System and a private one is stored on the email server. If a new email message is sent, a signature is issued using the private key and when the email is received, the signature is verified by the POP3/IMAP server using the public key. Thus, the recipient can easily recognize if the email is legitimate or if the sender’s address has been spoofed. A discrepancy will appear if the content of the email has been modified in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered messages are identical and that nothing has been added or deleted. This authentication system will increase your email security, since you can verify the legitimacy of the important emails that you get and your partners can do the exact same thing with the emails that you send them. Depending on the particular email service provider’s adopted policies, an email that fails the test may be removed or may be delivered to the recipient’s inbox with a warning.

DomainKeys Identified Mail in Shared Hosting

If you host a domain in a shared hosting account from our company, all the obligatory records for using the DomainKeys Identified Mail functionality will be set up by default. This will happen once you add the domain name in the Hosted Domains section of the Hepsia hosting Control Panel, on the condition that your domain also uses our NS records. A private encryption key will be created on our mail servers, while a public key will be added to the DNS system automatically by using the TXT resource record. Thus, you will not need to do anything manually and you’ll be able to take full advantage of all the benefits of this email validation system – your email messages will be delivered to any destination without being discarded and no one will be able to send out emails forging your addresses. The latter is very important if the type of your worldwide web presence suggests sending periodic newsletters or offers via email to prospective and current customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DKIM enabled by default, so if you select a semi-dedicated server 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 set up automatically – a private cryptographic key on our email servers for the electronic signature and a TXT resource record carrying the public key for the DNS database. As the DKIM protection is set up for a particular domain name, all addresses created using it will have a signature, so you won’t have to worry that the messages that you send out may not be delivered to their destination email address or that somebody may forge any of your email addresses and attempt to spam/scam people. This may be quite important in case you rely on electronic communication in your business, since your associates and/or clients will be able to distinguish authentic email messages from counterfeit ones.
