DomainKeys Identified Mail, or DKIM, is a system for confirming the legitimacy of an email message using an e-signature. When DomainKeys Identified Mail is enabled for a certain domain name, a public cryptographic key is published to the global Domain Name System and a private one is stored on the mail server. If a new message is sent, a signature is issued using the private key and when the email is delivered, the signature is checked by the POP3/IMAP mail server using the public key. Thus, the receiver can easily distinguish if the message is legitimate or if the sender’s address has been spoofed. A mismatch will occur if the content of the email message has been modified 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 authentication system will strengthen your email security, as you can verify the genuineness of the important email messages that you get and your associates can do the exact same thing with the emails that you send them. Depending on the particular mail service provider’s adopted policy, an email that fails to pass the check may be removed or may reach the recipient’s inbox with a warning notification.

DomainKeys Identified Mail in Website Hosting

You’ll be able to make the most of DomainKeys Identified Mail with each website hosting plans that we offer without the need to do anything in particular, because the required records for using this email authentication system are created automatically by our web hosting platform when you add a domain to an active account via the Hepsia Control Panel. If the given domain name uses our name server records, a private key will be created and stored on our email servers and a TXT resource record with a public key will be sent to the DNS system. In case you send out periodic email messages to customers or business collaborators, they will always be received and no unsolicited party will be able to spoof your address and make it look like you have composed a given message.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated plans come with DomainKeys Identified Mail enabled by default, so if you opt for this type of hosting and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the email validation system will be created automatically – a private cryptographic key on our mail servers for the electronic signature and a TXT record carrying the public key for the global DNS database. Since the DKIM protection is set up for a particular domain name, all email addresses created under it will have a signature, so you won’t have to worry that the emails that you send may not reach their destination address or that someone may fake any of your addresses and attempt to scam/spam people. This may be very important when you rely on email communication in your business, since your partners and/or customers will be able to distinguish legitimate email messages from phony ones.
