How do I block someone who is emailing me via answers?

This guy is so nasty. His pic is a close up of his crotch in a thong. He posts questions that are perverse. Now he has emailed me. I know how to block addresses but when a mail comes through answers it does not give you the users actual address. Is there anyway to block this guy. Here is the email he sent me.........


From: Kumar





Subject: you are sexy, I am sending you more naked pictures. My **** needs you





Oh and I am not the type to report people for every little thing they say or do here.....but I have reported him twice now and I am doing it again.

Perhaps you can set a filter?


Under Yahoo mail, select Options%26gt;Filters


For the filter settings, set


BODY contains Kumar


and


HEADER contains [the email addy which Yahoo Answers sent the message to you]





Hope this helps.





PS Personally I would forward this mail to Yahoo Customer Care and see what they can do about this Kumar guy
