>>Do they also allow you to search for the original sender? No not via sender search, as the encapsulated email is part of the BODY of the container email.
So usually you have to search via body search. >>And, again, what is the overall benefit to the end user from this scheme? Benefit is that email can be verified in a more streamlined way, which minimizes phishing and spam, if no servers are authorized to use any other’s email address, even if forwarding an email. It benefits users in the long run, as less and less people will be scammed by bank phishing and similar schemes, making email a more secure communication medium, by using already established systems like SPF, DMARC and DKIM to verify email’s legitimacy.
