DomainKeys Identified Mail, or DKIM, is a method for confirming the genuineness of an email message by using an electronic signature. When DKIM is enabled for a certain domain, a public encryption key is published to the global DNS system and a private one is stored on the mail server. If a new email message is sent, a signature is issued using the private key and when the email message is received, that signature is ‘scanned’ by the incoming POP3/IMAP email server using the public key. In this way, the receiver can easily know if the message is authentic or if the sender’s email address has been spoofed. A discrepancy will occur if the content of the email message has been altered in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or removed. This email authentication system will boost your email safety, as you can validate 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 given mail service provider’s adopted policy, a message that fails to pass the check may be removed or may show up in the receiver’s mailbox with a warning symbol.
DomainKeys Identified Mail in Shared Hosting
The DomainKeys Identified Mail option is pre-activated for all domain names that are hosted in a shared hosting account on our cloud platform, so you won’t need to do anything on your end to activate it. The sole requirement is that the given domain should be hosted in an account on our platform using our MX and NS resource records, so that the email messages will go through our mail servers. The private key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global DNS database automatically, so you will not need to do anything manually on your end in order to activate this option. The DKIM validation system will permit you to send trustable email messages, so if you are sending offers or a newsletter to clients, for example, your emails will always reach their target viewers, whereas unauthorized 3rd parties won’t be able to spoof your email addresses.
