Interesting.  I was just about to disagree with you, but I decided to go
back and read the RFC to make sure.  I was wrong.

Strict RFC822 compliance requires a "Date:" header, a "From:" header, and
at least one recipient header.  I find this interesting because sendmail,
which I think of as the ultimate authority on RFC822, is perfectly willing
to accept a message with no headers at all.

I'm glad I looked before I shot my mouth off.
