DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email message using a digital signature. When DKIM is enabled 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 ‘scanned’ by the incoming POP3/IMAP server using the public key. In this way, the recipient can easily distinguish if the message is legitimate or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email message has been modified 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 added or removed. This email authentication system will strengthen your email security, since you can verify the genuineness of the important email messages that you receive and your associates can do likewise with the messages that you send them. Based on the given email provider’s adopted policy, an email message that fails to pass the examination may be removed or may show up in the recipient’s inbox with a warning sign.
DomainKeys Identified Mail in Web Hosting
The DomainKeys Identified Mail functionality is activated by default for all domain names that are hosted in a web hosting account on our cloud web hosting platform, so you will not have to do anything on your end to turn it on. The only condition is that the particular domain name should be hosted in a hosting account on our platform using our MX and NS resource records, so that the emails will go through our email servers. The private cryptographic key will be generated on the server and the TXT record, which contains the public key, will be published to the global Domain Name System automatically, so you will not have to do anything manually on your end in order to activate this functionality. The DomainKeys Identified Mail validation system will allow you to send out trustable e-mails, so if you are sending offers or a newsletter to customers, for instance, your emails will always reach their target destination, while unsolicited third parties will not be able to forge your email addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
All necessary DomainKeys Identified Mail records will be created automatically by our cloud hosting platform when you add a domain name as hosted in a semi-dedicated server account, so in case you choose to purchase a semi-dedicated plan, you will not have to configure anything to be able to use the email authentication system. The domain must use our name servers so that its DNS resource records can be managed by us and as long as this requirement is answered, a private cryptographic key will be generated on our mail servers and a public key will be published to the DNS database by a special TXT resource record. All email addresses that you create with the domain name will be protected by DomainKeys Identified Mail, which will make it impossible for 3rd parties to forge any email address. Both you and your partners or customers can take advantage of this option, as it will ensure a higher safety level for your electronic communication.
