DomainKeys Identified Mail, or DKIM, is a system for confirming the genuineness of an email message by using an e-signature. When DomainKeys Identified Mail is activated for a given domain name, a public cryptographic key is published to the global DNS database and a private one is kept on the mail server. When a new message is sent, a signature is issued using the private key and when the message is received, that signature is authenticated by the incoming POP3/IMAP server using the public key. Thus, the receiver can easily discern if the email is genuine or if the sender’s email address has been spoofed. A discrepancy will occur if the content of the email message has been modified on its way as well, so DKIM can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or removed. This authentication system will boost your email security, as you can validate the genuineness of the important email messages that you receive and your partners can do the exact same thing with the email messages that you send them. Based on the particular mail service provider’s policies, an email that fails the check may be deleted or may emerge in the recipient’s inbox with a warning notification.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated plans come with DKIM activated by default, so in case you opt for this type of hosting and you add a domain 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 global Domain Name System. Since the protection is set up for a given domain name, all e-mail addresses created under it will carry a signature, so you won’t need to worry that the emails that you send out may not reach their destination address or that someone may fake any of your addresses and attempt to spam/scam people. This may be extremely essential when you rely on email communication in your business, as your colleagues and/or clients will be able to distinguish legitimate emails from forged ones.
