By RFC2822 section 3.6, the only required header fields are the date
and originator address.  The Subject field is optional.  The Message-ID
SHOULD be present (section 3.6.4) and is in common practice added by
the first "real" mail server the message hits if the client software
did not put one on (RFC 2821 section 6.3 "Compensating for
Irregularities").

Producing a message containing neither Subject nor Message-ID headers
is not polite, but is not technically broken behaviour.
