Authentication Protocols:

These protocols are highly significant to ISP’s as they help verify the legitimacy of sender and protect subscribers from spam / tricky emails.

1- SPF:
This protocol verifies the identity of sender by checking if sending IP address matches a list of authorized senders for that domain.

This protocol uses a set of encrypted keys to verify the true identity of a sender.
