Exchange Server 2013/2016: How to Create a Smarthost

Overview 

What you’ll need:

1. A Paubox Account
2. Access to your organization's Exchange Management Console
3. The smarthost value - provided by Paubox during setup

Additional Considerations / Pre-requisites:

1. Public IP: Paubox will need your exchange server's public IP address in order to accept the connection and your organization's email. One way to verify the sending ip is to look in a header from the customer.
2. DNS: You will need to update your DNS/TXT records in advance to include Paubox

Instructions 

To setup Paubox Encrypted Email for Exchange 2013, you’ll need to create a Smarthost using the Exchange Admin Center.

After the smarthost is created, you don’t need to restart any services or reboot. The changes take effect immediately.

Here’s how to do it:

1. Login to your Exchange Admin Center.
2. Select mail flow from the side bar on the left.
3. Select send connectors from the options at the top.
4. Click on the pencil icon (edit button).
5. Select delivery from the side bar.
6. Select the option Route mail through smart hosts.
7. Click on the plus symbol to add a smarthost.
8. Type in the provided smarthost value and click save.
9. Click save again and you're ready to go. 

NOTE: If there is an existing connector where the name has been changed, and you're unsure about it, just create a new one using Type: Internet. Then have the customer disable the old one.
