DomainKeys Identified Mail, or DKIM, is a method for confirming the legitimacy of an email message using an e-signature. When DomainKeys Identified Mail is enabled for a specific domain name, a public encryption key is published to the global Domain Name System and a private one is stored on the email server. When a new message is sent, a signature is issued using the private key and when the email is received, that signature is ‘scanned’ by the incoming POP3/IMAP server using the public key. Thus, the recipient can easily know if the message is genuine or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email has been modified in the meantime as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the delivered emails are identical and that nothing has been attached or removed. This validation system will increase your email safety, as you can validate the legitimacy of the important emails that you get and your colleagues can do the same with the emails that you send them. Based on the particular email provider’s adopted policies, a message that fails to pass the test may be removed or may enter the receiver’s mailbox with a warning symbol.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail functionality is pre-enabled for all domains that are hosted in a shared hosting account on our cloud website hosting platform, so you won’t have to do anything on your end to activate it. The sole condition is that the given domain should be hosted in an account on our platform using our NS and MX records, so that the e-mail messages will go through our mail servers. The private cryptographic key will be created on the server and the TXT resource record, which contains the public key, will be published to the global Domain Name System automatically, so you won’t need to do anything manually on your end in order to enable this feature. The DKIM authentication system will permit you to send out credible e-mails, so if you’re sending a newsletter or offers to customers, for example, your email messages will always reach their target destination, whereas unauthorized 3rd parties won’t be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

If you select one of the Linux semi-dedicated servers that we are offering, you’ll be able to use the DomainKeys Identified Mail feature with any domain name that you add to your brand-new semi-dedicated account without any manual setup, as our top-notch cloud web hosting platform will set up all the obligatory records automatically, as long as the domain name uses our name servers. The latter is required for a TXT record to be created for the domain, since this is how the public key can become available in the global DNS database. The private key will also be added automatically to our email servers, so every time you send a new email, it will include our system’s electronic signature. The number of junk email messages continues to rise each year and very often counterfeit email addresses are used, but when you use our web hosting services, you and your customers or colleagues won’t have to bother about that.
