Alas, there is no world-wide central authority that handles this.

All you can do: forward those mails to your e-mail service provider (contact customer service for the details on where to send to) and ask them to adjust their spam filters so these will be intercepted in the future. It's an ongoing struggle between spammers on one side and the anti-spam community on the other side and the e-mail providers have a big role in that.
