Problem with latest version on RH 5.2

[Erik Bloodaxe]

I am finding that some messages which have negative SPAM scores are 
taged with {Spam?}.  This appears not to be a spamassasin problem but 
some interaction between spamassasin and MailScanner.  the versions are 
SpamAssassin version 3.2.4  running on Perl version 5.8.8.  Can anyone 
assist?  I am unsure of how to track down where the problem lies.  The 
install is a standard of RedHat 5.2 and a standard install of 
MailScanner (tar file version)?

I have some example messages but do not want to share these with the list.

Regards
