We just recently upgraded our mail server from Exchange 5.5 to Exchange 2003. It works just fine except that unlike in Exchange 5.5, SMTP is enabled by default in Exchange 2003 --- w/c automatically gives my users permission to send emails to contacts outside my network.

In Exch5.5, if I want to restrict my users in sending external emails, I'll just have to remove their SMTP, but now in 2003 I cannot do so bec. it's configured by default.

How do I restrict them?

Please help.
