Add-IPAllowListProvider

This cmdlet is available or effective only on Edge Transport servers in on-premises Exchange. Use the Add-IPAllowListProvider cmdlet to create IP Allow list providers that are used by the Connection Filtering agent on Edge Transport servers.

Description

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

Examples

-------------------------- Example 1 --------------------------

Add-IPAllowListProvider -Name "Contoso.com Allow List" -LookupDomain allowlist.contoso.com -AnyMatch $true

This example adds a new IP Allow list provider and configures connection filtering to treat any IP address status code returned from the IP Allow list provider as a match and allow the connection. You get the value for the LookupDomain parameter from the allow list provider.

-------------------------- Example 2 --------------------------

Add-IPAllowListProvider -Name "Fabrikam.com Allow List" -LookupDomain allowlist.fabrikam.com -BitmaskMatch 127.1.0.1

This example adds an IP Allow list provider and configures a bitmask return value from the provider. You get the values for the LookupDomain and BitmaskMatch parameters from the allow list provider.

Required Parameters

-LookupDomain

The LookupDomain parameter specifies the host name that's required to use the allow 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 allowlist.spamservice.com. The actual value you need to use is provided by the allow list provider.

Type:SmtpDomain
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-Name

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

Type:String
Position:1
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016

Optional Parameters

-AnyMatch

The AnyMatch parameter specifies whether any response by the allow 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 allow list provider, any response code returned by the allow list provider causes connection filtering to allow messages from that source.

Type:$true | $false
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-BitmaskMatch

The BitmaskMatch parameter specifies the bit mask status code that's returned by the allow list provider. Use this parameter if the allow 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
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-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
Aliases:cf
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-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
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-Enabled

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

Type:$true | $false
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-IPAddressesMatch

The IPAddressesMatch parameter specifies the IP address status codes that are returned by the allow list provider. Use this parameter if the allow 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. You can enter multiple IP addresses separated by commas.

Type:MultiValuedProperty
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-Priority

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

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

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