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.

iprev

• The IP reverse, verified by looking 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.
