DomainKeys Identified Mail, or DKIM, is a method for verifying the genuineness of an email message using an e-signature. When DomainKeys Identified Mail is enabled for a particular domain name, a public encryption key is published to the global Domain Name System and a private one is kept on the email server. When a new email message is sent, a signature is generated using the private key and when the email message is delivered, the signature is validated by the incoming POP3/IMAP server using the public key. Thus, the recipient can easily discern if the email is authentic or if the sender’s email address has been forged. A discrepancy will appear if the content of the email message has been changed in the meantime as well, so DKIM can also be used to make sure that the sent and the received messages are identical and that nothing has been attached or removed. This email validation system will increase your email safety, since you can verify the authenticity of the important email messages that you get and your partners can do the same with the email messages that you send them. Based on the particular mail service provider’s policy, a message that fails to pass the examination may be deleted or may show up in the receiver’s inbox with a warning symbol.

DomainKeys Identified Mail in Shared Hosting

In case you host a domain in a shared hosting account from our company, all the compulsory records for using the DomainKeys Identified Mail option will be set up by default. This will happen the moment you add the domain name in the Hosted Domains section of the Hepsia Control Panel, as long as the domain also uses our NS resource records. A private cryptographic key will be created on our email servers, while a public key will be sent to the global DNS database automatically using the TXT resource record. In this way, you won’t need to do anything manually and you’ll be able to make use of all the benefits of this email validation system – your messages will be sent to any audience without being denied and no one will be able to send out email messages faking your email addresses. The latter is really important in case the nature of your web presence involves sending periodic newsletters or offers via email to potential and existing customers.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated hosting plans come with DomainKeys Identified Mail enabled by default, so if you opt for a semi-dedicated hosting package and you add a domain using our name servers through your Hepsia Control Panel, the records required for the validation system will be created automatically – a private key on our mail servers for the digital signature and a TXT record carrying the public key for the DNS system. As the DKIM protection is set up for a certain domain name, all email addresses created with it will have a signature, so you will not have to worry that the emails that you send may not be delivered to their target email address or that somebody may fake any of your addresses and try to spam/scam people. This may be extremely important in case you use email communication in your business, as your partners and/or clients will be able to distinguish authentic emails from fake ones.
