Option to turn off sending email alerts or forward invite addy to designated email

I am having trouble with invite emails getting spammed and potentially black listing me my site. My web host has threatened to suspend and or terminate my account now. The problem lies with invite emails. What I am wondering is if there is a way to have invites forwarded to a specified email addy and I could send them to designated party via gmail account that would not spam the messages and cause my host to drop me. Until I can work out a better solution I am going to have to remove the invite mod from my site or risk getting suspended. Any help greatly appreciated!
