DomainKeys Identified Mail, or DKIM, is a method for verifying the legitimacy of an email message using an electronic signature. When DKIM is activated for a given domain name, a public encryption key is published to the global DNS database and a private one is kept on the mail server. When a new email message is sent, a signature is issued using the private key and when the email is delivered, that signature is authenticated by the incoming POP3/IMAP server using the public key. Thus, the receiver can easily know if the email message is authentic or if the sender’s address has been spoofed. A discrepancy will appear if the content of the email has been edited in the meantime as well, so DKIM can also be used to ensure that the sent and the received emails are identical and that nothing has been attached or erased. This authentication system will increase your email safety, since you can confirm the genuineness of the important email messages that you receive and your colleagues can do the exact same thing with the messages that you send them. Depending on the particular mail service provider’s adopted policy, a message that fails the test may be removed or may appear in the receiver’s inbox with a warning sign.

DomainKeys Identified Mail in Shared Hosting

If you get any of the shared hosting plans that we’re offering, the DomainKeys Identified Mail functionality will be activated by default for any domain that you register under your web hosting account, so you won’t need to set up any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our NS and MX records (so that the email messages associated with this domain name will be handled by our cloud web hosting platform), a private cryptographic key will be generated immediately on our email servers and a TXT record with a public key will be sent to the Domain Name System. All addresses created using this domain name will be protected by DomainKeys Identified Mail, so if you send emails such as periodic newsletters, they will reach their target audience and the recipients will know that they are legitimate, since the DKIM feature makes it impossible for unauthorized parties to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated plans come with DKIM activated by default, so in case you pick a semi-dedicated hosting plan and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the validation system will be created automatically – a private key on our mail servers for the digital signature and a TXT resource record carrying the public key for the global DNS system. Since the protection is set up for a certain domain name, all addresses created using it will carry a signature, so you won’t need to worry that the email messages that you send out may not be delivered to their destination email address or that somebody may spoof any of your email addresses and attempt to spam/scam people. This may be extremely important in case you rely on email communication in your business, as your colleagues and/or customers will be able to distinguish real email messages from false ones.
