DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email by using a digital signature. When DKIM is enabled for a certain domain name, a public encryption key is published to the global DNS system and a private one is kept on the email server. When a new message is sent, a signature is generated using the private key and when the email message is delivered, the signature is ‘scanned’ by the POP3/IMAP mail server using the public key. Thus, the receiver can easily recognize if the email message is legitimate or if the sender’s address has been spoofed. A discrepancy will appear if the content of the email message has been altered in the meantime 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 attached or removed. This validation system will enhance your email safety, as you can confirm the genuineness of the important emails that you receive and your partners can do the same with the messages that you send them. Depending on the particular email service provider’s policy, an email that fails to pass the examination may be erased or may reach the recipient’s inbox with a warning sign.

DomainKeys Identified Mail in Shared Website Hosting

When you obtain any of the Linux shared website hosting packages that we are offering, the DomainKeys Identified Mail option will be enabled as standard for any domain name that you add to your shared web hosting account, so you won’t need to set up any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our MX and NS resource records (so that the emails associated with this domain will be handled by our cloud platform), a private encryption key will be issued straight away on our email servers and a TXT record with a public key will be sent to the global DNS system. All addresses set up using this domain will be protected by DKIM, so if you send out email messages such as periodic newsletters, they will reach their target audience and the receivers will know that they are authentic, since the DKIM option makes it impossible for unsolicited individuals to spoof your e-mail addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting packages come with DomainKeys Identified Mail activated by default, so if you opt for a semi-dedicated hosting plan and you add a domain using our name servers through your Hepsia Control Panel, the records required for the validation system will be created automatically – a private encryption key on our email servers for the digital signature and a TXT record carrying the public key for the Domain Name System. Since the protection is set up for a particular domain, all addresses created with 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 target address or that somebody may fake any of your addresses and try to spam/scam people. This may be quite important if you rely on email communication in your business, since your partners and/or customers will be able to distinguish legitimate email messages from spoofed ones.
