I don't see that. Elaborate?

I do see that 2822 section 4 requires me to accept lots of additional "syntax forms", but I do not see where it requires me to accept an empty string and interpret that as an email message.

I guess I will back off of that statement: I had always assumed that since section 4.5 relax the restriction on multiple occurrences of fields, it also relaxed the minimums. But it never says that, and unlike section 3.6, it does not add a new table and it does not make any statement about which (if any) fields are required.

That said, I will stick by the statement that 822 (and 2822 for that matter) make no claims about what a receiver ought to do when it receives a message without the minimum required fields.
