OK, thanks. Is there a way to set up a rule so I can reject SPAM before it is forwarded for certain email addresses?

Thanks, I'm still not clear about this. Are you saying that even mail that MagicSpam flags as SPAM will forward to the Gmail box?

We have some users that want to forward their incoming email to Gmail. Does MagicSpam check mail that is being forwarded to another mailbox and block SPAM without forwarding the SPAM message?
