Filtering out empty messages as spam

[Christian Andersson]

Hi there, I have recently been getting a higher amount of empty messages 
in my mailbox, from what I can see these messages are some type of spam 
or spamrelated. they might be some kind of tests to see if the 
mail-server can be used to send spam.

anyway regardless of what they are, I would like to be able to filter 
these messages out as "spam" attempts so that our users never gets those 
messages.

Is there some matcher in james that can do this?  match on an empty 
message (by empty I mean one where the body containes only whitespaces.

I have included below one such message (with some parts changed ofcourse)
