DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an email has been sent by an authenticated email server or person. A digital signature is added to the header of the email message by using a private key. When the message is received, a public key that is available in the global Domain Name System is used to confirm who actually sent it and whether the content has been changed in any way. The fundamental task of DomainKeys Identified Mail is to block the widely spread spam and scam messages, as it makes it impossible to forge an email address. If a message is sent from an email address claiming to belong to your bank, for example, but the signature does not match, you will either not get the email message at all, or you’ll get it with a warning alert that most probably it’s not authentic. It depends on email providers what exactly will happen with an email message that fails the signature check. DKIM will also offer you an additional layer of safety when you communicate with your business associates, for instance, as they can see that all the email messages that you exchange are authentic and have not been modified in the meantime.
DomainKeys Identified Mail in Cloud Web Hosting
The DomainKeys Identified Mail option is enabled by default for all domains that are hosted in a cloud web hosting account on our cloud web hosting platform, so you won’t have to do anything yourself to activate it. The sole condition is that the particular domain name should be hosted in a web hosting account on our end using our MX and NS resource records, so that the e-mail messages will go through our mail servers. The private cryptographic key will be generated on the server and the TXT record, which includes the public key, will be published to the DNS database automatically, so you will not need to do anything manually on your end in order to enable this functionality. The DomainKeys Identified Mail authentication system will enable you to send out credible e-mails, so if you are sending offers or a newsletter to customers, for example, your email messages will always reach their target viewers, whereas unauthorized third parties won’t be able to forge your email addresses.
