Description

On Edge Transport servers, you need to be a member of the local Administrators group to run this cmdlet.

Examples

Example 1

Set-IPBlockListProvider Contoso.com -AnyMatch $true

This example configures connection filtering to block an IP address if any IP address status codes are returned by the IP Block list provider named Contoso.com.

Example 2

Set-IPBlockListProvider Contoso.com -Priority 1

This example sets the priority value to 1 for the IP Block list provider named Contoso.com.

Parameters

-AnyMatch

The AnyMatch parameter specifies whether any response by the block list provider is treated as a match. Valid input for this parameter is $true or $false. The default value is $false. When this parameter is set to $true and connection filtering sends the IP address of the connecting SMTP server to the block list provider, any response code returned by the block list provider causes connection filtering to block messages from that source.

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

-BitmaskMatch

The BitmaskMatch parameter specifies the bit mask status code that's returned by the block list provider. Use this parameter if the block list provider returns bitmask responses. Valid input for this parameter is a single IP address in the format 127.0.0.1.

Type:IPAddress
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

-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.

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 specifies whether the connection filtering uses this IP Block list provider. Valid input for this parameter is $true or $false. The default value is $true. By default, connection filtering uses new IP Block list providers that you create.

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

-Identity

The Identity parameter specifies the IP Block list provider that you want to modify. You can use any value that uniquely identifies the IP Block list provider. For example:

  • Name
  • Distinguished name (DN)
  • GUID
Type:IPBlockListProviderIdParameter
Position:1
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-IPAddressesMatch

The IPAddressesMatch parameter specifies the IP address status codes that are returned by the block list provider. Use this parameter if the block list provider returns IP address or A record responses. Valid input for this parameter one or more IP addresses in the format 127.0.0.1.

To enter multiple values and overwrite any existing entries, use the following syntax: Value1,Value2,...ValueN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

To add or remove one or more values without affecting any existing entries, use the following syntax: @{Add="Value1","Value2"...; Remove="Value3","Value4"...}.

Type:MultiValuedProperty
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

-LookupDomain

The LookupDomain parameter specifies the host name that's required to use the block list provider. Connection filtering sends the IP address of the connecting SMTP server to the host name value that you specify. An example value is blocklist.spamservice.com. The actual value you need to use is provided by the block list provider.

Type:SmtpDomain
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

-Name

The Name parameter specifies a descriptive name for the IP Block list provider.

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

-Priority

The Priority parameter specifies the order that the Connection Filtering agent queries the IP Block list providers. A lower priority integer value indicates a higher priority. By default, every time that you add a new IP Block list provider, the entry is assigned a priority of N+1, where N is the number of IP Block list provider services that you have configured.

If you set the Priority parameter to a value that's the same as another IP Block list provider service, the priority of the IP Block list provider that you add first is incremented by 1.

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

-RejectionResponse

The RejectionResponse parameter specifies the text that you want to include in the SMTP rejection response when messages are blocked by connection filtering. The argument can't exceed 240 characters. If the value contains spaces, enclose the value in quotation marks (").

You should always specify the block list provider in the response so that legitimate senders can contact the block list provider for removal instructions. For example, "Source IP address is listed at the Contoso.com block list provider".

Type:AsciiString
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

-WhatIf

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.

Type:SwitchParameter
Aliases:wi
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
