DomainKeys Identified Mail, or DKIM, is a method for verifying the legitimacy of an email message by using a digital signature. When DKIM is activated for a given domain, a public cryptographic key is published to the global DNS system and a private one is stored on the email server. If a new email is sent, a signature is generated using the private key and when the email is received, that signature is checked by the POP3/IMAP mail server using the public key. In this way, the recipient can easily recognize if the message is authentic or if the sender’s address has been spoofed. A mismatch will appear if the content of the email message has been changed on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the delivered email messages are identical and that nothing has been attached or erased. This authentication system will enhance your email security, as you can confirm the genuineness of the important emails that you get and your colleagues can do the same with the email messages that you send them. Based on the particular email provider’s adopted policy, an email that fails the check may be erased or may enter the receiver’s mailbox with a warning symbol.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail option is activated by default for all domain names that are hosted in a cloud hosting account on our cloud web hosting platform, so you won’t need to do anything on your end to activate it. The only requirement is that the given domain should be hosted in a hosting account on our platform using our NS and MX resource records, so that the email messages will go through our email 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 DNS system automatically, so you won’t have to do anything manually on your end in order to enable this functionality. The DKIM validation system will enable you to send out trustworthy messages, so if you are sending a newsletter or offers to customers, for instance, your emails will always reach their target destination, whereas unauthorized 3rd parties won’t be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

When you opt for one of the Linux semi-dedicated hosting that we’re offering, you will be able to use the DKIM protection service with any domain that you add to your brand new semi-dedicated hosting account without any manual intervention, as our cutting-edge cloud platform will create all the required records automatically, on the condition that the domain uses our name servers. The latter is required for a TXT resource record to be created for the domain name, since this is how the public encryption key can become available in the global Domain Name System. The private key will also be added automatically to our mail servers, so every time you send a new message, it will have our system’s electronic signature. The number of junk email messages continues to increase every year and quite frequently bogus email addresses are used, but when you make use of our web hosting services, you and your clients or partners will not have to bother about that.
