Parameter Required Type Description

Action

Optional

Microsoft.Exchange.Data.Directory.SystemConfiguration.BlockedSenderAction

The Action parameter specifies the action that the Sender Filter agent takes on the message when a blocked sender or domain is found. The Action parameter takes the following values: StampStatus or Reject. The default value is Reject.

BlankSenderBlockingEnabled

Optional

System.Boolean

The BlankSenderBlockingEnabled parameter specifies whether all messages that don't contain a sender address are blocked. Valid input for the BlankSenderBlockingEnabled parameter is $true or $false. The default setting is $false. When the BlankSenderBlockingEnabled parameter is set to $true, all messages that don't contain a sender in the SMTP MAIL FROM: statement are blocked.

BlockedDomains

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The BlockedDomains parameter specifies one or more domain names. When the Sender Filter agent encounters a message that's been sent from a domain on this list, the Sender Filter agent takes the action specified in the Action parameter. Wildcard characters, such as an asterisk (*), are permitted. The maximum number of entries for this parameter is 800.

BlockedDomainsAndSubdomains

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The BlockedDomainsAndSubdomains parameter specifies one or more domain names. When the Sender Filter agent encounters a message that's been sent from a domain or a subdomain on this list, the Sender Filter agent takes the action specified in the Action parameter. Wildcard characters, such as an asterisk (*), are permitted. The maximum number of entries for this parameter is 800.

BlockedSenders

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The BlockedSenders parameter specifies one or more SMTP addresses. When the Sender Filter agent encounters a message that's been sent by a sender on this list, the Sender Filter agent takes the action specified in the Action parameter. The maximum number of entries for this parameter is 800.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch 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 switch.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory. The DomainController parameter isn't supported on the Edge Transport server role. The Edge Transport server role writes only to the Active Directory Lightweight Directory Services (AD LDS) instance.

Enabled

Optional

System.Boolean

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

ExternalMailEnabled

Optional

System.Boolean

The ExternalMailEnabled parameter specifies whether all messages from unauthenticated connections from servers external to your organization are processed by the Sender Filter agent. 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 from servers external to your organization are processed by the Sender Filter agent.

InternalMailEnabled

Optional

System.Boolean

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

RecipientBlockedSenderAction

Optional

Microsoft.Exchange.Data.Directory.SystemConfiguration.RecipientBlockedSenderAction

The RecipientBlockedSenderAction parameter specifies the action to take for messages sent by senders that were blocked by individual users in your organization. When the users add senders to their Blocked Senders list, SafeList aggregation adds these senders to the Blocked Senders list. This parameter specifies the action that the Sender Filter agent takes on the messages received from these senders. Valid input for the ExternalMailEnabled parameter is Delete or Reject.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, 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 switch.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Anti-spam features" entry in the Transport Permissions topic.

This example makes the following modifications to the Sender Filter agent configuration:

  • It enables blocking of blank senders.
  • It blocks the domain and subdomains of lucernepublishing.com.
  • It defines two blocked senders.
Set-SenderFilterConfig -BlankSenderBlockingEnabled $true -BlockedDomainsAndSubdomains *lucernepublishing.com -BlockedSenders user1@contoso.com,user2@contoso.com
