SOLUTION

This article applies to Exchange 2007 and 2010.

If your organization uses Exchange as their Mail Transport Agent, it is required to configure an SMTP Connector to route mail messages to the NET SatisFAXtion SMTP Gateway.

Information needed prior to performing this set up:
  • The IP Address of the NET SatisFAXtion server. This should be a static IP address. The fax server should not be using DHCP.
  • Choose an SMTP Domain Name to use to route mail to the fax server. It should be unique. Choose something that is recognizable as the domain used by the fax server. A good choice would be your company's normal email domain with a "fax." in front of it. For instance fax.company.com.
    This will be the "This Machines Fully Qualified Domain Name" from SMTP Gateway Setup on the fax server (see screenshot below).

Prior to performing this set up:
  • Install the SMTP Gateway on the fax server. Use the IP address of your Exchange server as the Outbound (SMTP) E-mail Server, and the SMTP Domain Name from above as "This Machines Fully Qualified Domain Name."



1. Add a Send Connector to the Hub Transport
Open the Microsoft Exchange Management Console. Expand Orgainization Configuration. Right-click on Hub Transport, and choose New Send Connector.

This will launch the New SMTP Send Connector wizard.

Enter the name of this connector. It is recommended to name the connector the same as the address space this connector will handle.

Click Next.

Now add the Address Space that this connector will handle. This will be the Fax Server's SMTP Domain Name that you entered when installing the SMTP Gateway.
Click the Add button and enter the address space, then click OK. The address space will show up in the list in the Domain column.

Click Next.

Now add the smart host that will handle this domain. Click Add and enter the IP address of the fax server, then click OK. Do not enter your Exchange server's IP address as that will create a mail loop.

Click Next.

Do not enable any authentication.

Click Next.

Now the wizard will associate this connector with a Hub Transport server. Enter the server you would like to use; this will depend on your Exchange infrastructure. If you only have one Exchange server, then this should be automatically filled in.

Click Next.

Finally, the wizard will present a summary of this connector's settings.

You are finished. Click New.

Advanced Configuration
You may also create the Send Connector with the following Exchange Management Shell command:
new-SendConnector -Name 'fax.company.com' -Usage 'Custom' -AddressSpaces 'smtp:fax.company.com;1' -DNSRoutingEnabled $false -SmartHosts '[192.168.10.10]' -SmartHostAuthMechanism 'None' -UseExternalDNSServersEnabled $false -SourceTransportServers 'EXCHANGE2007'
2. Disable Out of Office and Auto Replies
This will prevent users' out of office notices being sent to the fax server. Non-fax emails to this domain will be rejected as invalid faxes.

Open the Microsoft Exchange Management Console. Expand Orgainization Configuration. Right-click on Hub Transport, and choose New Remote Domain. This will launch the New Remote Domain wizard.Exchange200709.gif
Enter the name of this Remote Domain entry. It is recommended to name the connector the same as the address space this connector will handle.
Enter the Domain Name. This will be the same as the SMTP Domain Name of the SMTP Gateway, and the Address Space of the SMTP Send Connector.

Click New.

The remote domain will be created. Click Finish.

Once it is created, right-click on it and select Properties. On the general tab for Out-of-office message types delivered to this remote domain, select Allow none.

Change to the Message Format tab.

Disable Allow automatic replies.

Click OK.

3. Enable Message Relaying
This will allow your fax server to relay mail to non-domain email addresses. You will only need to perform this step if your fax server is on a different domain.

Expand Server Configuration. Select Hub Transport, then select your server. In the lower Receive Connectors area, right-click and select New Receive Connector. This will launch the New SMTP Receive Connector wizard.

Enter the name of this connector. It is recommended to name the connector the same as the address space this connector will handle. Intended use is Custom.
Exchange200714.gif
Click Next.

Change the Local Network settings if needed for your environment. Otherwise, continue.
Exchange200715.gif
Click Next.

Remove the default 0.0.0.0-255.255.255.255 remote IP addresses. Instead, add the IP address of your fax server.
Exchange200716.gif
Click Next.

Exchange200717.gif
Click New.

Click Finish.

Find the Receive Connector you just created. Right-click on it and select Properties. Select the Authentication tab, then check Externally Secured, and uncheck every other item.

Finally, go to the Permission Groups tab and check "Exchange Servers" and "Anonymous Users."

Click OK.

Advanced Configuration
You may also create the Receive Connector with the following Exchange Management Shell command:
new-ReceiveConnector -Name 'fax.company.com' -AuthMechanism 'ExternalAuthoritative' -Usage 'Custom' -Bindings '0.0.0.0:25' -RemoteIPRanges '192.168.10.10' -Server'EXCHANGE2007' -PermissionGroups ExchangeServers,AnonymousUsers
