Set-RecipientFilterConfig

The BlockedRecipients parameter specifies one or more SMTP addresses. To enter multiple SMTP addresses, separate the addresses by using a comma. The maximum number of individual SMTP addresses that you can input is 800.

The BlockListEnabled parameter specifies whether the Recipient Filter agent blocks messages sent to recipients listed in the BlockedRecipients parameter. Valid input for the BlockListEnabled parameter is $true or $false. The default setting is $false. When the BlockListEnabled parameter is set to $true, the Recipient Filter agent blocks messages sent to recipients listed in the BlockedRecipients parameter.

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

• Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
• Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

The DomainController parameter isn't supported on Edge Transport servers. An Edge Transport server uses the local instance of Active Directory Lightweight Directory Services (AD LDS) to read and write data.

The Enabled parameter specifies whether the Recipient Filter agent is enabled on the computer on which you're running the command. 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're running the command.

The ExternalMailEnabled parameter specifies whether all messages received from unauthenticated connections by servers external to your organization are passed through the Recipient Filter agent for processing. 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 received from unauthenticated connections by servers external to your organization are passed through the Recipient Filter agent for processing.

The InternalMailEnabled parameter specifies whether all messages from authenticated sender domains that belong to authoritative domains in the enterprise are passed through the Recipient Filter agent for processing. 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 the enterprise are passed through the Recipient Filter agent for processing.

The RecipientValidationEnabled parameter specifies whether the Recipient Filter agent blocks messages addressed to recipients that don't exist in the organization. Valid input for the RecipientValidationEnabled parameter is $true or $false. The default setting is $false. When the RecipientValidationEnabled parameter is set to $true, the Recipient Filter agent blocks messages addressed to recipients that don't exist in the organization.

The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
