exim and spamd -vs- commandline spamassassin -t why does the scores varies ?

[Paul Griffith <pa...@cse.yorku.ca>]

Greetings,

I am trying to trackdown why some spam is scoring the way it is. Take a  
look at the sample header at the end of the e-mail.

Using spamd and exim I will get a score of 2.6, but in if I call  
spamassassin from the command line I get a score of 8.1.

via exim/spamd

X-Spam-Checker-Version: SpamAssassin 3.2.1 (2007-05-02) on  
bronze.cs.yorku.ca
X-Spam-Level: **
X-Spam-Status: No, score=2.6 required=2.7 tests=DATE_IN_PAST_03_06,
	DRUGS_ERECTILE,RCVD_IN_PBL,RDNS_NONE,STOX_REPLY_TYPE autolearn=disabled
	version=3.2.1

via commandline

spamassassin -t < spam1.mbs

This is not the first time, this has happened. I have four spam e-mails  
that  I have spam that are scored 1.8 via spamd and exim, but on the  
commandline spamassassin -t < spam-email I get a score of 23.

Any tips or pointers ?
