DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email message by using an e-signature. When DKIM is enabled for a particular domain, a public key is published to the global Domain Name System and a private one is kept on the mail server. If a new email is sent, a signature is issued using the private key and when the email is delivered, the signature is authenticated by the incoming POP3/IMAP server using the public key. Thus, the recipient can easily distinguish if the email message is authentic or if the sender’s email address has been forged. A discrepancy will occur if the content of the email message has been altered in the meantime as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the delivered messages are identical and that nothing has been attached or removed. This validation system will strengthen your email security, as you can verify the legitimacy of the important email messages that you get and your colleagues can do the exact same thing with the emails that you send them. Based on the particular mail service provider’s adopted policy, a message that fails the examination may be removed or may appear in the receiver’s mailbox with a warning sign.

DomainKeys Identified Mail in Hosting

If you get any of the hosting service that we offer, the DomainKeys Identified Mail functionality will be activated by default for any domain name that you add to your shard hosting account, so you will not have to set up any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our MX and NS resource records (so that the emails related to this domain will be handled by our cloud web hosting platform), a private key will be generated right away on our email servers and a TXT resource record with a public key will be sent to the DNS system. All email addresses set up with this domain will be protected by DKIM, so if you send out email messages such as regular newsletters, they will reach their target destination and the receivers will know that the messages are legitimate, as the DKIM functionality makes it impossible for unauthorized people to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated service come with DKIM enabled by default, so in case you opt for a semi-dedicated server plan and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the email authentication 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 global DNS database. As the protection is set up for a specific domain name, all e-mail addresses created using it will carry a signature, so you will not have to worry that the email messages that you send may not be delivered to their destination email address or that someone may fake any of your email addresses and try to scam/spam people. This may be really essential when you rely on email communication in your business, as your partners and/or customers will be able to distinguish genuine email messages from spoofed ones.
