[SpamCop-List] When to pull the plug?

[-=d00d=-]

Hello all, I have received 28,000 bounces this morning and I am pretty much 
done with this rubbish. I don't know what else to do but kill the account 
and post a notice on our company website explaining what has led to this and 
give instructions on how to contact our company without using email. I will 
probably create another account that will not be posted anywhere on the 
internet and chances are good it will be a challenge /response mailbox 
because we don't what else to do. Good luck to all you folks that have a 
spammer using your domain name to send spews.
