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.
Confirm	Optional	System.Management.Automation.SwitchParameter	The Confirm parameter causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm parameter.
DomainController	Optional	Microsoft.Exchange.Data.Fqdn	To specify the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to the Active Directory directory service, include the DomainController parameter on the command. The DomainController parameter is not supported on computers that have the Edge Transport server role installed. The Edge Transport server role writes only to the local ADAM instance.
Enabled	Optional	System.Boolean	Valid input for the Enabled parameter is `$true` or `$false`. The default setting is `$true`. When the Enabled parameter is set to `$true`, the Recipient Filter agent is enabled on the computer on which you are running the `Set-RecipientFilterConfig` cmdlet.
ExternalMailEnabled	Optional	System.Boolean	Valid input for the ExternalMailEnabled parameter is `$true` or `$false`. The default setting is `$true`. When the ExternalMailEnabled parameter is set to `$true`, all messages from unauthenticated connections are passed through the Recipient Filter agent for processing.
Instance	Optional	Microsoft.Exchange.Data.Directory.SystemConfiguration.RecipientFilterConfig	The Instance parameter enables you to pass an entire object to the command to be processed. It is mainly used in scripts where an entire object must be passed to the command.
InternalMailEnabled	Optional	System.Boolean	Valid input for the InternalMailEnabled parameter is `$true` or `$false`. The default setting is `$false`. When the InternalMailEnabled parameter is set to `$true`, all messages from authenticated sender domains that belong to authoritative domains in your enterprise are passed through the Recipient Filter agent for processing.
RecipientValidationEnabled	Optional	System.Boolean	Valid input for the RecipientValidationEnabled Enabled parameter is `$true` or `$false`. The default setting is `$false`. When the RecipientValidationEnabled parameter is set to `$true`, the Recipient Filter agent blocks messages that contain recipients that do not exist in your organization.
WhatIf	Optional	System.Management.Automation.SwitchParameter	The WhatIf parameter instructs the command to simulate the actions that it would take on the object. By using the WhatIf parameter, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf parameter.

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 Blocked Recipient list and how to add recipients to the Blocked Recipient list.

The BlockedRecipients parameter takes multiple values. When you pass a value to the BlockedRecipients parameter, the existing value is replaced with the new value. For more information about how to add or remove values from multivalued properties, see Modifying Multivalued Properties.
