Is Recipient Validation enabled in MS Exchange 2007 & 2010?

Scenario:

How do I determine the Recipient Validation status in MS Exchange 2007 & 2010?
Is Recipient Validation enabled in MS Exchange 2007 & 2010?

Solution:

This solution is for Exchange Servers 2007 and 2010 and using the anti-spam agent for exchange. Recipient Validation is a feature in the Edge Transport Server. However if you don't have Edge Transport Server it is possible to install the anti-spam agent in the Hub Transport Server. Instructions for this can be found here.

To check if the Recipient Validation is enabled you need to do the following:

  1. Start the Exchange Management Shell (EMS)
  2. Type the following:

    Get-RecipientFilterConfig | fl RecipientValidationEnabled

The displayed result will be a boolean (True or False). If true then the Exchange Server is set to validate email addresses.
