all the [SPAM] emails that have made it into my inbox have a score of 
 >10, and my spam threshold is 5. They're way over over the score, all of 
them, and yet mimedefang is letting them through....(?) it's still a 
mystery.
Here is a text copy of a couple of those spam emails including headers:
http://www.zen187664.zen.co.uk/spam/spam1.txt
http://www.zen187664.zen.co.uk/spam/spam2.txt
you can see in the headers the spam scores are up. Please remember that 
mimedefang is actually rejecting a lot of spam email on my server, but 
somehow letting others through.
One thing I have noticed is that every [SPAM] email that gets to my 
inbox has:
'------=_NextPart_000_0007_01CAA19B.BF010B80--'
or something similar at the end.
