Description

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

Set-SenderReputationConfig -SrlBlockThreshold 6 -SenderBlockingPeriod 36

This example makes the following modifications to the sender reputation configuration:

It sets the SRL blocking threshold to 6.

It sets the number of hours that senders are put on the blocked senders list to 36 hours.

Parameters

-Confirm

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.
Type:SwitchParameter

Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-DomainController

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.

Type:Fqdn
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Enabled

The Enabled parameter enables or disables sender reputation on the Exchange server. Valid values are:

  • $true: Sender reputation is enabled. This is the default value.
  • $false: Sender reputation is disabled.
Type:Boolean
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ExternalMailEnabled

The ExternalMailEnabled parameter allows or prevents sender reputation from processing messages from unauthenticated connections that are external to your Exchange organization. Valid values are:

  • $true: Sender reputation is enabled on mail from external sources. This is the default value.
  • $false: Sender reputation is disabled on mail from external sources.
Type:Boolean
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-InternalMailEnabled

The InternalMailEnabled parameter allows or prevents sender reputation from processing messages from authenticated sender domains that are authoritative domains in your Exchange organization. Valid values are:

  • $true: Sender reputation is enabled on mail from internal sources.
  • $false: Sender reputation is disabled on mail from internal sources. This is the default value.
Type:Boolean
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-OpenProxyDetectionEnabled

The OpenProxyDetectionEnabled parameter allows or prevents sender reputation from attempting to connect to the message's source IP address to send a test message back to the Exchange server. This test determines if the sender is an open proxy server. Valid values are:

  • $true: Open proxy server detection is enabled. This is the default value.
  • $false: Open proxy server detection is disabled.

Open proxy server detection requires the following open outbound TCP ports in your firewall: 23, 80, 1080, 1081, 3128, and 6588.

If your organization uses a proxy server for outbound Internet access, you also need to define the properties of the proxy server by using the ProxyServerName, ProxyServerPort, and ProxyServerType parameters.

The values of the OpenProxyDetectionEnabled and SenderBlockingEnabled parameters can both be set to $true, but they both can't be set to $false. If one value is $true and the other is $false, and you change the $true value to $false, the parameter that was previously $false will automatically change to $true.

Type:Boolean
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ProxyServerName

The ProxyServerName parameter specifies the name or IP address of your organization's proxy server. Sender reputation uses this value to connect to the Internet for open proxy server detection.

The default value is blank ($null). To clear this value, use the value $null.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ProxyServerPort

The ProxyServerPort parameter specifies the port number that's used by your organization's proxy server. Sender reputation uses this value to connect to the Internet for open proxy server detection.

The default value is 0.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ProxyServerType

The ProxyServerType parameter specifies the type of your organization's proxy server. Sender reputation uses this value to connect to the Internet for open proxy server detection. Valid values are:

  • None: This is the default value.
  • Cisco
  • HttpConnect
  • HttpPost
  • Socks4
  • Socks5
  • Telnet
  • Wingate

-SenderBlockingEnabled

The SenderBlockingEnabled parameter allows or prevents sender reputation from blocking senders when their sender reputation level (SRL) meets or exceeds the value of the SrlBlockThreshold parameter. Valid values are:

  • $true: Sender blocking is enabled. This is the default value.
  • $false: Sender blocking is disabled.

You can temporarily block senders for up to 48 hours when you use the SenderBlockingPeriod parameter.

The values of the OpenProxyDetectionEnabled and SenderBlockingEnabled parameters can both be set to $true, but they both can't be set to $false. If one value is $true and the other is $false, and you change the $true value to $false, the parameter that was previously $false will automatically change to $true.

Type:Boolean

Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-SenderBlockingPeriod

The SenderBlockingPeriod parameter specifies the number of hours that a sender remains on the blocked senders list when their SRL meets or exceeds the value of the SrlBlockThreshold parameter. Valid input for this parameter is an integer from 0 through 48. The default value is 24.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-SrlBlockThreshold

The SrlBlockThreshold specifies the SRL rating that must be met or exceeded for sender reputation to block a sender. Valid input for this parameter is an integer from 0 through 9. The default value is 7.

Messages are blocked only when the SenderBlockingEnabled parameter is set to $true.
