Fax error on SBS 2003: Mail system DLL is invalid

WineGeek asked
Last Modified: 2010-08-05
I've configured our SBS 2003 to router incoming faxes to the owner's mailbox. I've tried using both the external email address and the .local mail address with no success. I've searched eventid.net and google for answers but am not finding much. I've already tried what eventid.net suggested, which is this:

I have found that McAfee VirusScan Enterprise 8.0's port blocking feature will cause this error message. It will only prevent connections from port 25 to port 25 on the same computer, so other e-mail functions will appear to work. Disabling this port blocking rule from the VirusScans’s Console solved the issue for me.

In my case, port 25 was blocked by the firewall. I added fxssvc.exe to the exception list for port 25 and the problem was solved.

From a newsgroup post: "You might try to following:
1. Open Server Management.
2. Right-click on Fax (Local) container.
3. Select "Properties".
4. Select "Receipts" tab.
5. In the Message Box, enable the "Enable Message Boxes as receipts" checkbox.
6. In SMTP E-mail, check the following:
a. "Enable SMTP Receipts e-mail receipts delivery" is enabled.
b. "Use these SMTP Settings for the Route through E-mail incoming routing method" is enabled.
c. Under Authentication, try setting to Anonymous access if not set already".

So, anyone have any suggestions as to why I'm getting this error message when I right-click a successfulyl received fax in the fax console and click Mail? Thanks.
