The main purpose of email authentication is to authenticate the identities of the parties who are taking part in the transmission of a message, as they are the ones who are authorized to amend the message. The outcomes of such substantiation and verification can then be used in distribution decisions, which are undeniably beyond the scope of email authentication proper, and are pretty different in nature from content filtering.


Some of the key reasons why email authentication is highly imperative are:

2.Diminishes and Defends Against Spoofing and Phishing - Spoofing is a technique time and again used by spammers so as to encroach into another person’s or company’s email address to get users to see through a message. Phishing is referred to as sending an email that tries to swindle recipients and he or she end up giving out their personal information, such as username, credit card numbers or account passwords. The email acts as if to be from an authentic source, such as a user’s bank, credit card Company, or online Web merchant. Most phishing spikes come from email in which the sender’s name in the “From Line” has been counterfeit or hoaxed. However, through email authentication provision it has been found that there has been significant reduction in spoofing and phishing spikes because those specific components of email deception are identity-based.
