Today we will create a new send connector for our Exchange 2010 server.
Its always good to have your information ready and written down :-
- Name of send connector to be created
- SMTP address space – e.g *.mail.contoso.com
- Smart hosts IP address – IP address of SMTP smarthost servers you want to associate this new connector with
- Source servers that will route your emails – your Exchange hub transport servers
Once ready, you can run below Exchange powershell command, replace it with your own information:-
new-SendConnector -Name “MYSENDCONNECTORNAME” -Usage Custom -AddressSpaces “SMTP:*.mail.contoso.com;1” -IsScopedConnector $true -DNSRoutingEnabled $false -SmartHosts “[192.168.11.12]”,”[192.168.11.13]” -SmartHostAuthMechanism None -UseExternalDNSServersEnabled $false -SourceTransportServers “LAB-HCP01″,”LAB-HCP02″,”LAB2-HCP01″,”LAB2-HCP02”
You can refer to MS article below for a full detail information about each important attribute to be configured on your send connector such as:-
Usage type:- For Send connectors, the usage type is basically a descriptive label that identifies what the Send connector is used for. All usage type values receive the same permissions.
Network settings:– Configure how the Send connector routes mail: by using DNS or by automatically forward all mail to a smart host.
Address spaces :- Configure the destination domains that the Send connector is responsible for.
Scope :- Configures the visibility of the Send connector to other Exchange servers in the organization.
Source servers:– Configure the Exchange servers where the Send connector is hosted. Mail that needs to be delivered by using the Send connector is routed to one of the source servers.

NOTE:- You can specify SMTP address spaces or non-SMTP address spaces on Send connectors that are configured on Hub Transport servers. You can only specify SMTP address spaces on Send connectors that are configured on Edge Transport servers.

Hi Jay, thanks for this article. I am a bit new to Exchange so please forgive me if I am being ignorant to some things.
I am on exchange 2016. I am trying to create a new send connector via powershell, and I hoped you will help with some pointers. My command and the error are:
[PS] C:\>New-SendConnector -Name `MYSENDCONNECTORNAME’ -Usage `Internet` -AddressSpaces `SMTP:*;1′ -IsScopedConnector $false -DNSRoutingEnabled $false -SmartHosts `MY.SMART.HOST.IP’ -SmartHostAuthenticationm `None’ -UseExternalDNSServersEnabled $false -SourceTransportServers `MYEXCH_SERVER’
Cannot process argument transformation on parameter ‘Usage’. Cannot convert value “Internet -AddressSpaces” to type
“Microsoft.Exchange.Management.SystemConfigurationTasks.NewSendConnector+UsageType”. Error: “Unable to match the
identifier name Internet -AddressSpaces to a valid enumerator name. Specify one of the following enumerator names and
try again: Custom, Internal, Internet, Partner”
+ CategoryInfo : InvalidData: (:) [New-SendConnector], ParameterBindin…mationException
+ FullyQualifiedErrorId : ParameterArgumentTransformationError,New-SendConnector
+ PSComputerName : my.server.name
I hope this is making sense

Hello Mola, please check your script properly, when using quotation marks make sure it is open and closed properly. I can see missing quotation marks @ -Name “name” -Usage “Internet” – These small things when missed, can make PS to cry out :). I advice you to use Powershell ISE when writing your scripts to help you spot errors.
