DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email using a digital signature. When DKIM is enabled for a particular domain, a public key is published to the global DNS system and a private one is kept on the mail server. If a new message is sent, a signature is issued using the private key and when the message is received, the signature is validated by the POP3/IMAP email server using the public key. Thus, the recipient can easily recognize if the email message is legitimate or if the sender’s email address has been spoofed. A discrepancy will appear if the content of the email message has been altered in the meantime as well, so DKIM can also be used to make sure that the sent and the delivered email messages are identical and that nothing has been attached or removed. This validation system will boost your email security, since you can validate the authenticity of the important email messages that you receive and your associates can do likewise with the email messages that you send them. Based on the given mail service provider’s policies, an email message that fails to pass the examination may be deleted or may emerge in the receiver’s inbox with a warning sign.
DomainKeys Identified Mail in Hosting
If you host a domain in a hosting account from us, all the needed records for using the DomainKeys Identified Mail functionality will be set up by default. This will happen once you add the domain in the Hosted Domains section of the Hepsia Control Panel, as long as your domain also uses our NS records. A private key will be created on our mail servers, while a public key will be sent to the global DNS system automatically by using the TXT record. Thus, you won’t have to do anything manually and you’ll be able to enjoy all the benefits of this authentication system – your messages will reach any audience without being discarded and nobody will be able to send out email messages forging your e-mail addresses. The latter is really important in case the essence of your web presence involves sending out regular offers or newsletters via email to potential and current customers.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers come with DomainKeys Identified Mail activated by default, so in case you pick a semi-dedicated package and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the authentication system will be set up automatically – a private cryptographic key on our email servers for the e-signature and a TXT resource record carrying the public key for the DNS database. Since the protection is set up for a given domain, all addresses created under it will have a signature, so you will not need to worry that the email messages that you send out may not reach their destination email address or that someone may fake any of your addresses and try to scam/spam people. This may be very important when you rely on e-communication in your business, as your partners and/or customers will be able to distinguish real messages from forged ones.
