Following the general guidelines about being a "strict constructionist"
about what you send but a "liberal" about what you accept, you should
be prepared to accept out-of-order "received" fields from other hosts.
I'm pretty sure I've seen mail come in with "received" fields out of
order (i.e. after other fields, not just out of chronological order
among themselves), so it's a pretty safe bet that you'll get in trouble
if you count on everyone doing the right thing.
