Disarmed mail and spam checks

[Peter H. Lemieux]

I have my configuration set to deliver mail with Disarmed tags.  However 
it appears this arrangement exempts the message from spam processing.  I 
have a spam blacklist rule that should block a particular sender, but 
these messages still come through with the {Disarmed} tag.  I scanned 
the directives in MailScanner.conf, but didn't see how to handle this 
situation.

The only relevant thing I found online was this

a posting of the same problem with no replies.

Any suggestions? Thanks!
