Neither RFC x822, x8221 goes into the guidelines of how to handle "missing fields" but do indicate the minimum requirements:

 2822:  relaxes To:

     Date:
     From:

You will note that 2822 requires you to accept messages with *none* of these fields. (See section 4.) It only requires you to *send* messages with these fields (section 3). Now, you may decide that those restrictions are too lax and do something interesting in response to messages lacking any particular fields, but that's a local decision and not endorsed by 2822.

822 makes no claims about what a receiver ought to do when it receives a message without the minimum required fields.

For the record.
