DKIM, which is an acronym for DomainKeys Identified Mail, is a validation system, which stops email addresses from being forged and email content from being meddled with. This is done by attaching a digital signature to each and every email message sent from an email address under a specific domain. The signature is published on the basis of a private encryption key that’s available on the outbound SMTP email server and it can be validated by using a public key, which is available in the global Domain Name System. Thus, any email message with edited content or a forged sender can be spotted by mail service providers. This technology will strengthen your worldwide web safety noticeably and you will be sure that any e-mail sent from a business ally, a bank, etc., is an authentic one. When you send email messages, the receiver will also know for sure that you are indeed the one who has sent them. Any email that appears to be fake may either be labeled as such or may never appear in the recipient’s inbox, based on how the particular provider has chosen to deal with such emails.
