Applies to: Exchange Server 2013

Topic Last Modified: 2014-04-11

This cmdlet is available only in on-premises Exchange Server 2013.

Use the Test-SenderId cmdlet to test whether a specified IP address is the legitimate sending address for a specified SMTP address.

Test-SenderId -IPAddress <IPAddress> -PurportedResponsibleDomain <SmtpDomain> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-HelloDomain <String>] [-Server <ServerIdParameter>] [-WhatIf [<SwitchParameter>]]

This example checks whether the IP address is the legitimate sender address for the domain contoso.com.

Test-SenderId -IPAddress -PurportedResponsibleDomain contoso.com 

The Test-SenderId cmdlet provides the results of a Sender ID check for the IP address and the corresponding domain name that you specify.

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. To see what permissions you need, see the "Anti-spam features" entry in the Anti-spam and anti-malware permissions topic.


Parameter Required Type Description




The IPAddress parameter specifies the originating IP address of the sending server.




The PurportedResponsibleDomain parameter specifies the domain name that you want to verify with Sender ID.




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.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that retrieves data from 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.




The HelloDomain parameter specifies the domain address displayed in the HELO or EHLO SMTP commands from this sender.




The Server parameter specifies the Exchange server on which you want to run this command. You can use any value that uniquely identifies the server. For example:

  • Name

  • FQDN

  • Distinguished name (DN)

  • Exchange Legacy DN

If you don't use the Server parameter, the command is run on the local server.




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.
