DomainKeys Identified Mail, or DKIM, is a system for checking the legitimacy of an email message by using a digital signature. When DomainKeys Identified Mail is activated for a particular domain name, a public key is published to the global DNS system and a private one is kept on the mail server. When a new email message is sent, a signature is issued using the private key and when the message is delivered, the signature is validated by the POP3/IMAP server using the public key. In this way, the recipient can easily distinguish if the message is genuine or if the sender’s email address has been forged. A discrepancy will appear if the content of the email has been altered on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received emails are identical and that nothing has been attached or deleted. This email validation system will enhance your email security, since you can verify the legitimacy 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 particular email provider’s adopted policy, a message that fails to pass the test may be deleted or may emerge in the recipient’s inbox with a warning sign.
DomainKeys Identified Mail in Cloud Hosting
In case you host a domain name in a cloud hosting account from us, all the mandatory records for using the DomainKeys Identified Mail functionality will be created by default. This will happen as soon as you add the domain name in the Control Panel’s Hosted Domains section, on the condition that your domain also uses our NS resource records. A private encryption key will be created on our mail servers, whereas a public key will be published to the global DNS database automatically by using the TXT record. In this way, you will not have to do anything manually and you’ll be able to take full advantage of all the benefits of this email authentication system – your messages will be delivered to any audience without being rejected and nobody will be able to send messages faking your email addresses. The latter is quite important if the type of your web presence suggests sending periodic offers or newsletters via email to prospective and current customers.
DomainKeys Identified Mail in Semi-dedicated Hosting
All mandatory DomainKeys Identified Mail records will be set up automatically by our cloud hosting platform when you add a domain name as hosted in a semi-dedicated server account, so if you decide to purchase a semi-dedicated plan, you will not have to set up anything to be able to take advantage of the email validation system. The domain must use our name servers so that its DNS resource records can be managed by our company and as long as this condition is met, a private encryption key will be created on our email servers and a public key will be sent to the global Domain Name System by a special TXT resource record. All email addresses that you create using the domain will be protected by DKIM, which will make it impossible for 3rd parties to fake any address. Both you and your partners or customers can take advantage of this option, as it will guarantee a much higher level of security for your email communication.
