Hi, everyone!, i have a little problem, because i want to some users don't send a internet email, but they can send internal emails. HOw i configure that? I just wont to 2 users don't send internet email. I view the SMTP Connector and reject users, but this didn't work. Sorry for my very bad english Regards Alex
