Ditto John.  Although I am seeing more of these types of spams getting  
caught.  My error rate has increased somewhat because of them (I  
think).  For example, instead of pulling one or two legit emails from  
spambox per month out of 400-500000, I am pulling 4 or 5 ;-] The  
amount of spam we recieve has also increased about the same time I  
started recieving these stock quote spams.  Must be some money in  
these.  Although, I cant for the life of me imagine anyone dumb enough  
to bite on these spams.
