DomainKeys Identified Mail, or DKIM, is a system for checking the legitimacy of an email message by using an electronic signature. When DomainKeys Identified Mail is activated for a given domain, a public cryptographic key is published to the global DNS system and a private one is kept on the mail server. When a new message is sent, a signature is generated using the private key and when the email is delivered, the signature is ‘scanned’ by the incoming POP3/IMAP email server using the public key. Thus, the receiver can easily recognize if the email is authentic or if the sender’s address has been forged. A discrepancy will appear if the content of the email has been edited on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received email messages are identical and that nothing has been added or erased. This email authentication system will strengthen your email safety, since you can verify the legitimacy of the important emails that you receive and your associates can do likewise with the emails that you send them. Depending on the particular email provider’s adopted policies, an email message that fails to pass the check may be removed or may appear in the recipient’s mailbox with a warning symbol.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DKIM activated by default, so in case you opt for a semi-dedicated server package and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the email validation system will be set up automatically – a private 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 specific domain name, all email addresses created using it will have a signature, so you won’t need to worry that the email messages that you send out may not be delivered to their target address or that someone may forge any of your email addresses and attempt to scam/spam people. This may be quite important if you use e-communication in your business, since your colleagues and/or customers will be able to distinguish real email messages from counterfeit ones.
