Inception

• The idea of email authentication or verification is not completely new. For the reason that the way email was originally created, it is difficult to verify if an email is really coming from the person who alleges to be sending it. Actually, email authentication method solves the problem by verifying that the sending server is reliable.

Sender policy framework • SPF and Sender ID are quite easy to apply.

This authentication method depends on individual records linked to your domain that tells e-mail system that it is ok to receive e-mail from other system or domain on your behalf.

Domain keys identifies mail• Domain Keys are a pair of encryption keys that

are produced for validation. DKIM or domain keys identified mail inserts a private encrypted key in to each of your email to authenticate that it has really originated from someone you have allowed to send e-mail.

Author domain signing practices

• ADSP or author domain signing practices allows you to stipulate a policy for messages signed by the author's domain. An email id has to go through DKIM validation first, then ADSP can imply a punishing behavior if the message is not signed by the author's domain.

DMARC• It allows you to identify a

policy for valid messages. It reflects both DKIM and SPF as a joint email authentication technique. The "R" in DMARC, which is called reporting, provides feedback to the author domain. Thus, provides for informed policy framework.

Vouch by reference

• VBR or vouch by reference gives assurance to a previously validated identity. This method needs some globally accepted authorities that confirm the reputation of domains.

up the internet protocol address of the name just found, is just a signal that the IP was set up correctly in the DNS. The reverse declaration of a range of IP addresses can be given to the ADMD (Administrative Management Domain) that makes use of them, or can be managed by the network provider.

Conclusion

• Keeping up with these varying standards is not an easy job for the average e-mail marketer. Even though marketers do not want to apply email authentication methods themselves, they should at least make sure that somebody in the company is doing it for them.
