Spam Assassin Reject

[Sean Murphy]

I've installed Spam Assassin and MIMEDefang with Sendmail however I 
would like Spam Assassin to tell sendmail to "Reject" Spam on the 
connection.  Instead of accepting the spam and marking it so users then 
can filter on the spam tag.  Can Anyone share there code in the 
MIMEDefang Filter to do this.

Thanks
