In my experience, I have seen multiple email address in the From: with badly configured bounces, or display attack, or a repetition in the display part of the email address.
While people speak it is in the RFC to have multiple emails in the From, it is hard to catch a real use case in the wild.
I found it simpler to disallow it (unless it is the same domain which is repeated cf bugs above)
I found more troubling that the IEA spec allows now to not put an email address in the From: something like undisclosed-sender;
