Email authentication is one of the techniques which furnish messages of the email transport system with certifiable information. 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:
1.Diminishes and Defends against Spam - Spam usually creates a lot of tricky situations not only for the customers, but also for the marketers.

Through authenticated email ISPs and Mailbox providers can recognize the authentic email in a better manner. This ways it will become easier for the receiver to differentiate a spammer from an authentic sender. Authentication combined with email reputation and certification programs will eventually assist email receivers extricate authentic messages from spam.
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.
