SpamAssassin not running

[Jeff Adams]

Hello gang,

 First off, Thanks Julian for all of your hard work writing and
maintaining this package.  I think it's the best option out there for
what I'm trying to do and I appreciate the hard work.  --- so on to the
problem:

 I'm trying to setup an anti-spam mail gateway for my company and I'm
having trouble getting spamassassin to run from mailscanner.  The
incoming messages are getting procesed by mailscanner and delivered by
Sendmail, but my spam email tests aren't getting flagged by SA as spam.
 I think that SA isn't being called from MailScanner, but other than
looking in the headers, I can't tell how to determine if SA was run or
how to troubleshoot the problem further.  Has anyone ran into this
problem before?

Here are my stats:

 Sparc Solaris 7 / perl 5.8.0 / MailScanner 4.05-3 / SpamAssassin 2.43
 / all the appropriate perl modules.

PS: I'm not using any virus protection because that's being done ahead
of this mail gateway.  So I've disabled it in my config above.

Thanks!
