spamassassin not sending out spam header, help!

[Jana Nguyen <jn...@ncmir.ucsd.edu>]

Hi there,

I'm having difficulty sending out spam email with "spam mark" on the
email integrated with postfix mail server.
By running the test"spamassassin -D <
/usr/share/doc/spamassassin-3.1.1/sample-spam.txt", I get following
output below with
no sender or recipient email.  Furthermore, at the end of the output I
noticed "-0.0 NO_RECEIVED has no Received headers":

[birn-holly ~]# spamassassin -D <
/usr/share/doc/spamassassin-3.1.1/sample-spam.txt
