Error: 'C-0007 - Send failed:....' While Submitting a Fax Request Using SMTP – GFI FaxMaker Online Support

Overview

When the user tries to submit a fax request from the GFI FaxMaker Fax Message Form using SMTP as the connection type, the submission fails with the error:

"An error was encountered while sending the fax. Error: C-0007 - Send failed: make sure that you have your SMTP settings from the GFI FaxMaker Message Form options correctly set up."

This article provides the root cause and resolution steps for this issue.

Solution

This error occurs when using the FaxMaker Online client (SMTP option) or the FaxMaker Fax Message Form while either the sender email address is not present, or the SMTP server is not reachable or does not allow to relay the outbound email fax request. This error can also be encountered if the GFI FaxMaker Online SMTP server is unavailable, although this is highly unlikely and has only occurred on very rare occasions.

The solution is to correct the above issues by following these steps:

Launch the GFI FaxMaker Fax Message Form from your Windows programs menu.
Select View > Options > [TAB: Connection Settings] from GFI FaxMaker Fax Message form.
Verify whether the option Email (SMTP) is selected and if so, whether the sender Email address is present.

Verify whether the selected SMTP server is reachable using:

PING <SMTP SERVERNAME>

If successful, execute the below command to confirm connectivity to the SMTP server and verify whether SMTP relay is operational:

TELNET <SMTP SERVERNAME> 25

Note: The default SMTP server if using the GFI FaxMaker Online mail server is smtpfax1.gfifax.com on port 25 if not using a user-defined custom mail server.

If the telnet command is unsuccessful and after ruling out any environmental issues (firewall, connectivity, etc.),
this implies the unlikely event that the GFI FaxMaker Online SMTP server is down and should be immediately escalated by 
submitting a support request. In the meantime, you can still use your email to send faxes as described in 
Sending Faxes From Your Email Using FaxMaker Online or through the configuration described in the next step.

Alternatively, you can change the Connection type configuration in the Fax Message Form client from SMTP to HTTPS which is the recommended setting for sending faxes through GFI FaxMaker Online.

Testing

You should be able to successfully telnet into the SMTP server from port 25 as shown below:

telnet smtpfax1.gfifax.com 25

Note: If this test fails, check your network settings and the SMTP server settings (if relying on a custom mail server) and verify that no perimeter firewall or anti-virus/security tools are blocking the connection. In the unlikely event that the GFI FaxMaker Online SMTP server is unavailable, submit a support request with GFI FaxMaker Online Support and send faxes using the alternatives described above in the interim.

Send a test fax message to confirm that the outgoing faxes are now getting submitted for delivery without any error messages.
