DomainKeys Identified Mail, or DKIM, is a method for verifying the genuineness of an email by using an e-signature. When DKIM is activated for a certain domain name, a public key is published to the global Domain Name System and a private one is stored on the mail server. If a new email is sent, a signature is issued using the private key and when the email message is received, the signature is checked by the POP3/IMAP server using the public key. Thus, the recipient can easily recognize if the email message is legitimate or if the sender’s address has been spoofed. A mismatch will appear if the content of the email has been altered on its way as well, so DKIM can also be used to make sure that the sent and the received emails are identical and that nothing has been attached or removed. This email validation system will enhance your email safety, since you can verify the genuineness of the important emails that you get and your partners can do likewise with the messages that you send them. Depending on the particular mail service provider’s policy, an email that fails to pass the check may be removed or may reach the recipient’s inbox with a warning alert.
DomainKeys Identified Mail in Cloud Hosting
In case you host a domain name in a cloud hosting account from us, all the needed records for using the DomainKeys Identified Mail option will be added by default. This will happen the moment you add the domain name in the Hosted Domains section of the Hepsia Control Panel, on the condition that your domain also uses our NS records. A private key will be created on our mail servers, whereas a public key will be sent to the Domain Name System automatically by using the TXT resource record. In this way, you won’t have to do anything manually and you will be able to take advantage of all the benefits of this email validation system – your emails will reach any destination without being disallowed and nobody will be able to send out email messages forging your email addresses. The latter is pretty important in case the nature of your online presence involves sending out regular offers or newsletters via email to prospective and existing customers.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so if you pick a semi-dedicated package and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private encryption key on our mail servers for the digital signature and a TXT record carrying the public key for the global DNS system. Since the protection is set up for a specific domain, all addresses created using it will carry a signature, so you will not need to worry that the email messages that you send out may not be delivered to their destination address or that somebody may fake any of your email addresses and try to scam/spam people. This may be extremely essential if you rely on email communication in your business, as your partners and/or clients will be able to distinguish real email messages from fake ones.
