You only have to setup another machine if you want to be able to manually
route faxes to someone's email using the mail to feature described below.

To manually route a fax to someone's email, you would perform the following
steps:
1. open "Fax Console"
2. go to any fax tif file in any folder. (if there is no tif, create one)
3. right click on the file and select "Mail to..." option

However, these steps will produce the error "mail system dll is invalid" on
any Exchange server, including SBS 2003 (with out without SP1). As a
result, you cannot manually route faxes to a mailbox in SBS 2003 using the
'mail to' feature described above.

The 'mail to' feature described above has nothing to do with SBS 2003
automatically routing faxes to a user's mailbox. I fail to see how you
received the 'mail system dll is invalid' message with the automatic
routing. Nevertheless, here's what you should do next.

Verify that automatic routing is enabled for email and Sharepoint. There
are two ways to do this (A. Run the Configure Fax wizard or B. Check it
Manually). I will provide steps for both.

A. Run the Configure Fax wizard
===========================
1. Open the Server Management Console.
2. Click the To Do List.
3. Click the Configure Fax link.
4. Run the wizard.
  a. Make sure the "Route through E-mail" method is checked and that a
valid email address is specified.
  b. Make sure the "Store in a document library" method is checked and that
a valid document library is specified.
5. Finish the wizard.

B. Verify Fax Routing is Enabled and Configured.
==========================================
Enable E-mail Receipt
----------------------------------

1. Click Start, point to All Programs, point to Accessories, point to
Communications, point to Fax, and
   then click "Fax Service Manager".

2. In the console tree in the left panel, right-click the "Fax (Local)"
node, and then click Properties.

3. On the Receipts tab, verify the "Enable SMTP e-mail
   receipts delivery" check box is checked.

4. In the From e-mail address: box, type the e-mail address of the
   sender of the fax. For example, SBSFaxService@domain.local.

5. In the Server address: box, type the SBS server's NetBIOS computer
   name. Do not type the server's fully qualified domain name (FQDN). To
   determine the SBS server's NetBIOS computer name, type "hostname"
   (without the quotation marks) at the command prompt, and then press
   ENTER.

6. In the Port: box, type "25" (without the quotation marks). If the
   SMTP port has changed, type the appropriate port.

7. Verify the "Use these SMTP settings for the Route Through E-Mail
incoming routing method" check box is checked.

8. Click the Authentication button, verify the "Anonymous access"
   option is selected, and click OK.

NOTE: The authentication method you selected must match the authentication
method defined in the Exchange 2003 SMTP server. By default, it is set to
Anonymous access. To verify this:

1. Start the Exchange System Manager.

2. If the administrative groups are displayed, expand Administrative
   Groups, and then expand "<first administrative group>".

3. Expand Servers, expand <servername>, expand Protocols, and then
   expand SMTP.

4. Right-click "Default SMTP Virtual Server", click Properties, click the
Access tab, and click the Authentication button.

5. Verify Anonymous access is selected.

Enable Incoming Fax Routing Methods
---------------------------------------------------------

1. In the Fax Service Manager console, expand Devices and Providers, expand
Devices, expand <modem>, and click on Incoming Methods.

2. Verify the "Route through E-mail" method is enabled.

3. Right-click the "Route through E-mail" method and click Properties.
Click the E-mail tab and verify that a valid email address is specified.
Click OK.

4. Verify the "Store in a document library" method is enabled.

5. Right-click the "Store in a document library" method and click
Properties. Click the Fax Routing tab and verify that a valid document
library is specified. Click OK.

6. Restart the Fax service.
