You hit the nail on the head Andy.  Most of the "junk" coming in has  
the same "pretty" name but none of the actual email addresses repeat.   
Therefore the "blacklist" does not work as I have never recieved from  
the same address twice.  Most likely because they are creating bogus  
addresses for a one time spam.  So as I understand it, I should not  
bother trying to get horde to work as it's functionality is not there  
and need to go to a third party anti-spam program.  Thanks again for  
the information and assistance.
