banning domain names

[oldrow]

is there a way to prevent anyone with a .ru .info and .de email address from registering?  ALL of my real forum members have a .com or .edu email address and I want to kill the bots that are slowing down my forum.  I already use honeypot but it lets them through sometimes.
