DomainKeys Identified Mail, or DKIM, is a system for validating the legitimacy of an email message using a digital signature. When DomainKeys Identified Mail is activated for a given domain name, a public cryptographic key is published to the global Domain Name System and a private one is kept on the mail server. When a new message is sent, a signature is generated using the private key and when the email is received, that signature is validated by the incoming POP3/IMAP server using the public key. In this way, the receiver can easily know if the email is legitimate 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 DomainKeys Identified Mail can also be used to ensure that the sent and the received emails are identical and that nothing has been attached or erased. This email authentication system will boost your email security, as you can verify the legitimacy of the important email messages that you get and your colleagues can do the same with the messages that you send them. Depending on the given mail service provider’s policies, an email message that fails the check may be erased or may emerge in the recipient’s mailbox with a warning alert.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail feature is pre-activated for all domains that are hosted in a cloud hosting account on our cloud hosting platform, so you will not need to do anything on your end to enable it. The only requirement is that the particular domain name should be hosted in a web hosting account on our end using our NS and MX records, so that the emails will go through our mail servers. The private cryptographic key will be generated on the server and the TXT record, which includes the public key, will be published to the global DNS database automatically, so you won’t need to do anything manually on your end in order to enable this functionality. The DomainKeys Identified Mail validation system will allow you to send out trustworthy messages, so if you’re sending a newsletter or offers to clients, for example, your email messages will always reach their target viewers, while unsolicited third parties will not be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DomainKeys Identified Mail activated by default, so in case you pick a semi-dedicated server plan and you add a domain name 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 mail servers for the e-signature and a TXT record carrying the public key for the Domain Name System. As the DKIM protection is set up for a specific domain, all e-mail addresses created with it will carry a signature, so you will not need to worry that the messages that you send may not reach their destination email address or that someone may forge any of your addresses and try to scam/spam people. This may be really important in case you rely on e-communication in your business, since your associates and/or clients will be able to distinguish genuine emails from bogus ones.
