Add domains to Internal Relay on Exchange 2010

Posted on Aug 6, 2018Aug 6, 2018 by Josh U

Here is a quick step to add new domains to your internal relay on Exchange.

If you are not familiar with what internal relay means and what are its impact, you can head over to Microsoft technet and read more:- https://technet.microsoft.com/en-us/library/bb124423(v=exchg.150).aspx#Anchor_2

internaldomains

open up the EMC console and under Organization Configuration >> Hub Transport >> Accepted domains, in the actions menu, select New Accepted domain
Enter the display name, you can use a different name than the actual accepted domain or for me I prefer to keep it the same.
Select internal relay domain and save.

Via powershell command:-

new-AcceptedDomain -Name ‘contoso.com’ -DomainName ‘testdomain.com’ -DomainType ‘InternalRelay’

4. To verify that the new accepted domain is working, I usually like to test by sending a test message and then see the results, you can do this via powershell as follows:-

Send-MailMessage -From noreply@newcontoso.com -To “administrator@contoso.com” -Subject “Test internal relay ” -Body “Test only. Do not reply” -SmtpServer “name of your hub server”

View the result from message tracking log:-

Get-MessageTrackingLog -ResultSize unlimited -Start “08/06/2018 9:00AM” -Recipients “administrator@contoso.com” -sender noreply@newcontoso.com -Server”name of your hub server”

This will help you to know immediately if something was wrong with your configuration and you can go back and follow the steps again.

Create a New SendConnector – Exchange 2010

Posted on May 15, 2018Oct 28, 2019 by Josh U

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.

Add SMTP Server IP to SendConnector – Exchange 2010

Posted on May 11, 2018Oct 28, 2019 by Josh U

First get the existing information of your send connector and any smarthosts IP already configured.

Open exchange management shell and run:-

Get-SendConnector NAMEOFSENDCONNECTOR| fl identity, smarthosts, sourcetransportservers

Result:-

Identity: MYSENDCONNECTOR

SmartHosts : {[192.168.3.4]}

SourceTransportServers : {BB0-MOB4-HUB01, BB0-MOB2-HUB01}

From above result we can see our old smarthost IP that we want to change with the new one and the source transport servers (exchange hub transport servers) which this send connector applies to.

Now set the new IP via exchange management power shell ( this will replace the existing one if it already exists ):-

Set-SendConnector NAMEOFSENDCONNECTOR -SmartHosts “192.168.3.5” -Confirm

Note:-
<smarthosts> parameter
This parameter takes one or more FQDNs, such as server.contoso.com, or one or more IP addresses, separated by commas. If you enter an IP address, you must enter the IP address as a literal as follows, for example: 10.10.1.1. The smart host identity can be the FQDN of a smart host server, a mail exchange (MX) record, or an address (A) record. If you configure an FQDN as the smart host identity, the source server for the Send connector must be able to use DNS name resolution to locate the smart host server. (https://msdn.microsoft.com/en-us/subscriptions/aa998294(v=exchg.80).aspx)

To do this via Exchange Management Console in Exchange 2010:- Click on Hub Transport -> Send Connectors -> double click on your send connector -> Network -> under route mail through the following send connector, edit to add the new IP and remove the old one if needed. Ok to accept changes, check that the new IP is added. Test and do a telnet to your new smarthost IP.
