Use the Set-RecipientFilterConfig cmdlet to enable and configure the Recipient Filter agent on a computer that has the Edge Transport server role or the Hub Transport server role installed.

Syntax


`Set-RecipientFilterConfig [-BlockedRecipients <MultiValuedProperty>] [-BlockListEnabled <$true \| $false>] [-DomainController <Fqdn>] [-Enabled <$true \| $false>] [-ExternalMailEnabled <$true \| $false>] [-Instance <RecipientFilterConfig>] [-InternalMailEnabled <$true \| $false>] [-RecipientValidationEnabled <$true \| $false>]`

Parameters

Parameter	Required	Type	Description
BlockedRecipients	Optional	Microsoft.Exchange.Data.MultiValuedProperty	Valid input for the BlockedRecipients Enabled parameter is one or more SMTP addresses. You can enter up to 800 individual SMTP addresses for the BlockedRecipients this parameter.
BlockListEnabled	Optional	System.Boolean	Valid input for the BlockListEnabled Enabled parameter is `$true` or `$false`. The default setting is `$false`. When the BlockListEnabled parameter is set to `$true`, the Recipient Filter agent blocks messages that are sent to recipients that are listed in the BlockedRecipients parameter.

Detailed Description

To run the Set-RecipientFilterConfig cmdlet, the account you use must be delegated the following:

Exchange Server Administrator role and local Administrators group for the target server

To run the Set-RecipientFilterConfig cmdlet on a computer that has the Edge Transport server role installed, you must log on by using an account that is a member of the local Administrators group on that computer.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.

Example

The following code examples shows two Set-RecipientFilterConfig commands.

The first code example shows how to modify the recipient filter configuration so that recipient validation is enabled.

The second code example shows how to enable the IP Block list and how to add recipients to the blocked recipient list.

The BlockedRecipients property takes multiple values; when you pass a value to the BlockedRecipients property, the existing value is replaced with the new value. For procedural information that explains how to append values to and existing multi-value property, see Modifying Multivalued Properties.
