I am using Exchange 5.5 on an NT 4.0 box sr6. I have a local domain configuration as well as a registered domain. My question is, how do I set up a user to only have the capabilities of sending and receiving e-mail locally?
I have some temporary users who I do not want to be able to send and receive internet mail -- only local mail.
In Exchange 5.5, all of your Internet e-mail should be flowing through an Internet Mail Connector (IMC). Preventing someone from receiving Internet e-mail is easy: give them a bogus SMTP address (e.g., firstname.lastname@example.org). If a user does not have a valid Internet SMTP address, they will not be able to receive e-mail from the Internet.
You need to configure Delivery Restrictions on your IMC to prevent a user from sending Internet e-mail. Delivery restrictions allow users in the GAL to be restricted from or allowed to send on an IMC. The delivery restrictions information is held on a per IMC basis.
