DomainKeys Identified Mail, or DKIM, is a system for confirming the authenticity of an email message using a digital signature. When DKIM is enabled for a certain domain name, a public key is published to the global DNS system and a private one is stored on the email server. When a new email is sent, a signature is generated using the private key and when the email message is received, that signature is verified by the POP3/IMAP 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 forged. A mismatch will appear if the content of the email message 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 enhance your email safety, since you can validate the legitimacy of the important email messages that you get and your colleagues can do the same with the messages that you send them. Based on the given email service provider’s policy, an email that fails to pass the check may be deleted or may reach the recipient’s mailbox with a warning symbol.

DomainKeys Identified Mail in Cloud Hosting

If you order any of the cloud plans that we are offering, the DomainKeys Identified Mail functionality will be activated by default for any domain name that you register under your shared website hosting account, so you will not need to create any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our MX and NS records (so that the email messages related to this domain name will be handled by our cloud platform), a private key will be generated right away on our email servers and a TXT resource record with a public key will be sent to the global DNS database. All email addresses set up with this domain will be protected by DomainKeys Identified Mail, so if you send out emails such as regular newsletters, they will reach their target audience and the recipients will know that they are genuine, since the DKIM option makes it impossible for unauthorized parties to spoof your addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated hosting plans come with DomainKeys Identified Mail activated by default, so in case you choose a semi-dedicated server plan and you add a domain using our name servers via your Hepsia Control Panel, the records required for the authentication system will be set up automatically – a private key on our email servers for the electronic signature and a TXT resource record carrying the public key for the Domain Name System. Since the DKIM 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 reach their destination address or that somebody may forge any of your addresses and attempt 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 real emails from forged ones.
