Where to get spam?

[secbasics () dusty ece cmu edu]

Does anyone know organizations which give away spam captures? I mean, obviously I will get lots of spam just from 
posting on this list (;)) but I would like to 
get more to analyze. It seems like every couple months some student does a project which requires spam but they always 
have to start from ground zero. Isn't 
there anywhere which gives spam to security researchers?

Thanks
