By having users use vacation without a filter to stop it from replying to 
spam, or accepting virus mail then generating a new error, you are engaged 
in a DDOS against the people who's address is forged into the mail. We have 
users getting 3-6 THOUSAND such bounces a day.

So yes, I'm glad SpamCop is blocking sites that do this.
