Is anyone else having trouble with these image spams getting past  
your spam filters?  I'm getting quite a bit of it daily and since it  
has random generated text along with a unique gif image, Mail.app and  
Thunderbird are unable to spot it as Junk.  I can't think of a way to  
deal with it other than writing a rule to mark all messages as Junk  
if they have a gif attached but that could mean that a lot of legit  
mail never makes it to me.
