Set-IPBlockListProvider

 

Applies to: Exchange Server 2013

Topic Last Modified: 2014-04-11

This cmdlet is available or effective only on Edge Transport servers in on-premises Exchange Server 2013.

Use the Set-IPBlockListProvider cmdlet to modify IP Block list providers that are used by the Connection Filtering agent on Edge Transport servers.

Set-IPBlockListProvider -Identity <IPBlockListProviderIdParameter> [-AnyMatch <$true | $false>] [-BitmaskMatch <IPAddress>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Enabled <$true | $false>] [-IPAddressesMatch <MultiValuedProperty>] [-LookupDomain <SmtpDomain>] [-Name <String>] [-Priority <Int32>] [-RejectionResponse <AsciiString>] [-WhatIf [<SwitchParameter>]]

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.

Set-IPBlockListProvider Contoso.com -AnyMatch $true 

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

Set-IPBlockListProvider Contoso.com -Priority 1

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.

Parameter Required Type Description

Identity

Required

Microsoft.Exchange.Configuration.Tasks.IPBlockListProviderIdParameter

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

AnyMatch

Optional

System.Boolean

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.

BitmaskMatch

Optional

System.Net.IPAddress

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.

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 Edge Transport servers. An Edge Transport server uses the local instance of Active Directory Lightweight Directory Services (AD LDS) to read and write data.

Enabled

Optional

System.Boolean

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.

IPAddressesMatch

Optional

Microsoft.Exchange.Data.MultiValuedProperty

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>.... If the values contain spaces or otherwise require quotation marks, you need to use the following syntax: "<value1>","<value2>"....

To add or remove one or more values without affecting any existing entries, use the following syntax: @{Add="<value1>","<value2>"...; Remove="<value1>","<value2>"...}.

LookupDomain

Optional

Microsoft.Exchange.Data.SmtpDomain

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.

Name

Optional

System.String

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

Priority

Optional

System.Int32

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.

RejectionResponse

Optional

Microsoft.Exchange.Data.AsciiString

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".

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.
