And this should prevent the "false sending"? I can't believe that it is that wide open... <sigh>
Todd 1. You have to use SMTP AUTH for ALL users. That means having NO MAIL RELAY checked in the SMTP security tab. It also means that everyone will have to go to the advanced settings on their e-mail client and check MY CLIENT REQUIRES AUTHENTICTION or they won't be able to send. But right now, you're letting anyone send anything they want from your server. 2. If you are using IMail 8.2, have the connect to port 587, it's already built in, and they will be able to connect to your server for authentication no matter where they are sending from.

Their user names and passwords will be their validation for sending mail through the server. Hope this helps.
