Email Nightmare..help!

My cinespot email address seems to be targeted by email spammers, they probably use my email as the return path when they send out spam emails, and so I have been getting tons of returned email every other day recently, from a few hundreds to a few thousands, which is really very very very annoying and troublesome....

i have asked quite some people and it seems that there is not much I can do. Anyone got similar experience and how do you usually deal with it?
