DomainKeys Identified Mail, or DKIM, is a system for validating the genuineness of an email message using a digital signature. When DKIM is enabled for a particular domain, a public encryption key is published to the global DNS database and a private one is kept on the mail server. If a new email is sent, a signature is generated using the private key and when the email is received, the signature is verified by the incoming email server using the public key. In this way, the receiver can easily know if the email message is genuine or if the sender’s email address has been spoofed. A discrepancy will occur if the content of the email has been altered in the meantime as well, so DKIM can also be used to make sure that the sent and the received messages are identical and that nothing has been attached or erased. This email authentication system will strengthen your email safety, since you can confirm the legitimacy of the important emails that you receive and your colleagues can do the same with the email messages that you send them. Based on the given email service provider’s policy, a message that fails to pass the examination may be deleted or may emerge in the receiver’s mailbox with a warning flag.

DomainKeys Identified Mail in Shared Hosting

When you get any of the shared service that we are offering, the DomainKeys Identified Mail functionality will be activated by default for any domain that you register under your hosting account, so you won’t need to set up any records or to activate anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our MX and NS records (so that the emails related to this domain will be handled by our cloud hosting platform), a private key will be generated straight away on our mail servers and a TXT record with a public key will be sent to the DNS database. All addresses created with this domain will be protected by DomainKeys Identified Mail, so if you send email messages such as periodic newsletters, they will reach their target destination and the receivers will know that they are authentic, as the DomainKeys Identified Mail feature makes it impossible for unsolicited parties to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated service come with DomainKeys Identified Mail activated by default, so if you opt for a semi-dedicated plan and you add a domain using our name servers through your Hepsia Control Panel, the records required for the validation system will be set up automatically – a private cryptographic key on our mail servers for the e-signature and a TXT resource record carrying the public key for the global DNS system. Since the DKIM protection is set up for a certain domain, all addresses created under it will carry a signature, so you won’t have to worry that the emails that you send out may not be delivered to their destination email address or that somebody may spoof any of your addresses and try to spam/scam people. This may be quite essential when you use email communication in your business, as your partners and/or customers will be able to distinguish genuine email messages from false ones.
