Bouncing spam emails back where they belong

My gmail account gets a lot (and I mean a lot) of spam these days. One site coming from Russia sends me about 4 emails every minute. Drives me crazy.

Apple used to have a way to bounce the emails back which (usually) stops them after a while. However, this feature disappeared a while back.

This link (http://www.maclife.com/article/howtos/how_bounce_emails_mac_os_x_mail) will show you how to get it back. Works like a charm too.
