DKIM, which stands for DomainKeys Identified Mail, is a validation system, which impedes email addresses from being forged and email content from being manipulated. This is done by attaching a digital signature to every message sent from an address under a particular domain. The signature is created on the basis of a private key that is available on the outgoing server and it can be validated with a public key, which is available in the global DNS database. Thus, any email with modified content or a spoofed sender can be identified by email providers. This method will boost your online safety immensely and you’ll be sure that any e-mail sent from a business ally, a bank, etc., is authentic. When you send out email messages, the recipient will also know for sure that you are indeed the one who has sent them. Any email message that turns out to be fraudulent may either be labeled as such or may never appear in the recipient’s mailbox, based on how the particular provider has chosen to handle such messages.
