DomainKeys Identified Mail, or DKIM, is a system for verifying the legitimacy of an email message by using an e-signature. When DomainKeys Identified Mail is enabled for a given domain, a public cryptographic key is published to the global Domain Name System and a private one is stored on the mail server. When a new email message is sent, a signature is generated using the private key and when the email message is delivered, the signature is validated by the incoming POP3/IMAP mail server using the public key. Thus, the recipient can easily know if the email message is genuine or if the sender’s address has been forged. A discrepancy will appear if the content of the email has been changed on its way 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 deleted. This email authentication system will boost your email security, since you can verify the authenticity of the important emails that you get and your associates can do the same with the email messages that you send them. Based on the particular mail service provider’s policies, an email message that fails the test may be deleted or may enter the recipient’s mailbox with a warning alert.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated servers come with DKIM enabled by default, so in case you choose a semi-dedicated server package and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the validation system will be set up automatically – a private encryption key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the global DNS database. As the protection is set up for a certain domain name, all email addresses created with it will have a signature, so you won’t need to worry that the messages that you send may not reach their destination email address or that somebody may spoof any of your addresses and attempt to spam/scam people. This may be rather essential in case you use electronic communication in your business, since your colleagues and/or clients will be able to distinguish real messages from bogus ones.
