Overview

Faxmaker uploads received faxes to the customer's email server.  Sometimes due to a network error or an SMTP error thrown by the mail server, the upload may fail.  These attempts are logged in the smtpin.fmlogger.txt log file.  This article explains how to review these errors and how to troubleshoot them.  

Solution

1. Navigate to the FaxMaker logs directory, C:\Program Files (x86)\GFI\FaxMaker\logs by default.  
   
   
2. Open the smtpin.fmlogger.txt file in Notepad.  See the screenshot below.  
   
   
   
   
3. You can see the one item that failed due to an SMTP error.  We can also view this error a little differently in the fmmta.gfi_log.txt file.  See the screenshot below.  
   
   
4. We see the error in the fmmta.gfi_log.txt file and the timestamp in the smtp.fmlogger.txt file is the same.  We can also see the folder the service is scanning for files to upload.  When we navigate to that folder, C:\Program Files (x86)\GFI\FaxMaker\in\undeliverable, we can view any files there.
   
   
   
   
5. The file listed is a .queued file and is basically an email file and can be opened in Notepad.  Open this file and review it and see if it needs to be delivered to the end-user or if it can be deleted.  In the example above, this was a file being sent to someone that was not on the email server which was being sent to, therefore it was rejected by the mail server.  
   
   
   
   
6. The items in the C:\Program Files (x86)\GFI\FaxMaker\in\undeliverable folder are retried every 5 minutes and we can see this logged in the fmmta.gfi_log.txt file.  In the screenshot above,  by the timestamps, we see the email file being retried every 5 minutes.  Therefore if you have files in this folder it is best to remove them if they are unable to be delivered.
