You might also look at spamassassin, it can be hooked up to certain  
mail clients (kmail AFAIK) or be part of a [fetch}get]mail and  
procmail setup. It provides several rules checking for inline  
graphics and, on my setup is quite good at getting rid of image spam.  
Combined with the imageinfo plugin it gets even better. There's also  
an fuzzyocr plugin that scans the text in the image, if you have the  
cpu cycles, you might add that too. If you want to be really evil on  
any embedded graphic, simply increasing the scores on those rules to  
above your spam level makes sure no imbedded graphics (even the  
'good' ones) will end up in you inbox.
