Hi,
I'm sorry but I think the only professional solution for you would be to move hosts.
There's no problem upgrading the module to send the e-mail to more than one address but I wouldn't do that as standard as a matter of principle. I don't believe that anyone should try to run an e-commerce shop on an unreliable host, I wouldn't want my card details treated in this way so I won't advocate a system that would cause this situation for anyone else.
Hope I don't sound too harsh but you are playing with potential fraud and stress for customers here.
