DomainKeys Identified Mail, or DKIM, is a system for validating the legitimacy of an email message using an electronic signature. When DomainKeys Identified Mail is activated for a particular domain, a public encryption key is published to the global DNS database and a private one is stored on the email server. If a new email is sent, a signature is issued using the private key and when the message is received, that signature is checked by the incoming POP3/IMAP email server using the public key. Thus, the receiver can easily tell if the email is legitimate or if the sender’s address has been forged. A mismatch will occur if the content of the email message has been modified in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered messages are identical and that nothing has been added or erased. This authentication system will enhance your email safety, since you can validate the legitimacy of the important emails that you get and your partners can do the exact same thing with the messages that you send them. Based on the given email provider’s policy, a message that fails to pass the check may be erased or may be delivered to the receiver’s mailbox with a warning symbol.

DomainKeys Identified Mail in Shared Hosting

When you get one of the Linux shared hosting that we’re offering, the DomainKeys Identified Mail option will be enabled as standard for any domain name that you register under your shared account, so you won’t need to create any records or to enable 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 email messages related to this domain name will be handled by our cloud platform), a private encryption key will be generated right away on our email servers and a TXT record with a public key will be sent to the global Domain Name System. All email addresses set up with this domain name will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target audience and the receivers will be sure that the messages are authentic, because the DomainKeys Identified Mail option makes it impossible for unauthorized individuals to spoof your addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DKIM activated by default, so if you opt for a semi-dedicated server plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the email authentication system will be set up automatically – a private encryption key on our email servers for the e-signature and a TXT record carrying the public key for the global Domain Name System. As the protection is set up for a specific domain, all addresses created under it will have a signature, so you will not have to worry that the email messages that you send out may not reach their destination address or that someone may forge any of your email addresses and attempt to scam/spam people. This may be really important in case you use email communication in your business, as your partners and/or customers will be able to distinguish legitimate messages from forged ones.
