Block some mailboxes from Sending to Internet 1

[lwolfson]

Exchange 5.5 SP4 on W2K SP4. I need to do some training and want to block internet email for just a few mailboxes. I need to train on our app that hooks into Outlook, but am worried users would accidently send email to live addresses and need to prevent that.

Is there anyway I can block a user from sending external while allowing internal from the IMC?

Sure, in the properties of the IMS connector select the Delivery Restrictions tab and add the people you want to block to the "Reject Messages From" list. They can still send internal and will still receive from external but any attempt to send external will generate non-delivery.

There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. <ntxerver.WP1.WP1.local #5.5.0 smtp;552 sorry, your envelope sender domain must exist (#5.7.1)>
