How To Prevent An Exchange User From Sending and Receiving SMTP Emails

Here's a question that came up today.

How do you prevent an Exchange 2003 user from sending and receiving SMTP traffic through the internet, while still allowing them to receive emails from within the Exchange organization?

In the Exchange System Management tool, you have to add the account in question deny lists in two separate places.

The first place is Message Delivery in Global Settings of your organization. Here you go to Properties and select Recipient Filtering tab, add all SMTP addresses for accounts that you want to deny receipt of internet email.

Second place is in any Internet Mail SMTP Connectors you have for your organization. Go into the Properties for each connector and select the Delivery Restriction tab. Add the accounts in question to the Reject Messages From list.

Might take 15 minutes or so before the changes become active.

It did not work for me too! I've read all the guides. They are all the same. I've created the connector and I've done everything. I've waited for hours, but users are still able to send emails...

Have you tried removing the SMTP addresses for the users in question? If they've got x.400 or x.500 addresses, they should be able to communicate internally, right?

SMTP is central to Exchange 2000/2003. It won't let you remove a user's primary SMTP address.
