Block mail?

For the past week or so I've been continually receiving mail from an obvious scam to join the Cataclysm beta for 72 hours. The first mail was promptly reported and ignored, no big deal.

The next day, I get the exact same mail, copy/pasted, from the exact same person. This continues on for a few days, and even to the point of receiving the mail multiple times in a single day

I've already reported this person through email, but until this problem is gotten to I still have to put up with this scammer. Is there any way I can permanently block this person from sending me mail? Does the Ignore feature do this? Don't know why I never though of it before but I just ignored him now...
