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.
Parameters
-AnyMatch
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
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.
Parameter properties
| Type: | Boolean |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
(All)
| Position: | Named |
| Mandatory: | False |

| Value from remaining arguments: | False |
-BitmaskMatch
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
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.
Parameter properties
| Type: | IPAddress |
| Default value: | None |
| Supports wildcards: | False |

Parameter sets
(All)

-Confirm
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
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.

-DomainController
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
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.
Parameter properties

-Enabled
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
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.
Parameter properties
| Type: | Boolean |
| Default value: | None |
| Supports wildcards: | False |

-IPAddressesMatch
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
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.
Parameter properties
| Type: | MultiValuedProperty |

-LookupDomain
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
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.

-Priority
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
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.
Parameter properties
| Type: | Int32 |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
(All)
| Position: | Named |

-WhatIf
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
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.
