Consider the following scenario. You set the value for "Maximum number of recipients" in the "Transport Settings" to 0. You do this in Exchange Management Console on a Microsoft Exchange Server 2007 server. In this scenario, users cannot send email messages. Additionally, a Non Delivery Report (NDR) is not generated if someone tries to send an email message to one or more recipients.
This issue occurs because a NDR message has a recipient that is blocked by the Exchange Server 2007 server. However, a NDR is a system message which should be delivered.
To resolve this problem, install the following update rollup:
