Neither RFC x822, x8221 goes into the guidelines of how to handle

2822: relaxes To:
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.
