DomainKeys Identified Mail, or DKIM, is a method for checking the authenticity of an email message using a digital signature. When DomainKeys Identified Mail is enabled for a certain domain, a public key is published to the global Domain Name System and a private one is kept on the email server. When a new email message is sent, a signature is issued using the private key and when the message is delivered, that signature is verified by the incoming mail server using the public key. Thus, the recipient can easily tell if the email message is genuine or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email message has been altered on its way as well, so DKIM can also be used to make sure that the sent and the delivered email messages are identical and that nothing has been added or removed. This validation system will boost your email security, as you can verify the authenticity of the important email messages that you get and your colleagues can do the same with the emails that you send them. Depending on the given email provider’s adopted policies, an email that fails the test may be erased or may emerge in the recipient’s inbox with a warning symbol.

DomainKeys Identified Mail in Website Hosting

The DomainKeys Identified Mail feature is activated by default for all domains that are hosted in a website hosting account on our cloud web hosting platform, so you will not have to do anything on your end to activate it. The sole condition is that the given domain should be hosted in a hosting account on our platform using our MX and NS resource records, so that the email messages will go through our email servers. The private encryption key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global DNS system automatically, so you won’t have to do anything manually on your end in order to activate this feature. The DomainKeys Identified Mail authentication system will enable you to send trustworthy email messages, so if you’re sending a newsletter or offers to clients, for instance, your email messages will always reach their target audience, while unauthorized third parties won’t be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated servers come with DKIM activated by default, so in case you choose this type of hosting and you add a domain using our name servers through your Hepsia Control Panel, the records required for the authentication system will be created automatically – a private key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the DNS database. As the protection is set up for a specific domain name, all email addresses created under it will carry a signature, so you won’t have to worry that the email messages that you send out may not reach their destination address or that somebody may forge any of your email addresses and attempt to spam/scam people. This may be very important when you use email communication in your business, as your associates and/or clients will be able to distinguish real emails from spoofed ones.
