That would be exactly what I want.  Except, I would like to see why it 
decided to reject those emails.  I don't see anywhere it tells me why or 
gives me something I can tune.  If I look at the header of the reject 
message it sends to my Gmail account, I see:

X-Authentication-Warning: dcsnow.com: postfix set sender to <> using -f
X-MailScanner-Rejected: yes
From: aragonx at dcsnow.com
To: wyonker at gmail.com
Subject: Unrequested mail rejected
X-dcsnow-MailScanner: generated, Found to be clean
X-dcsnow-MailScanner-Information: Please contact the ISP for more 
information
X-dcsnow-MailScanner-ID: DBF0210A0C41.A9EC2
X-dcsnow-MailScanner-SpamScore: s
X-dcsnow-MailScanner-From:
X-Spam-Status: No

I remember in the past, if the spam score was 4 or more, it would reject 
it.  But that doesn't seem to be the case here.  It also doesn't give me 
a clue as to why it rejected it.  Or, I just don't understand what it is 
telling me.
