How to send faxes using the alias method

Faxes can be sent through GFI FaxMaker by using an alias to specify the fax number. This method works by placing the fax number as the alias and the GFI FaxMaker address as the email address as follows:


Example: 1234 <>

The recipient details can also be included when addressing the fax. This can be achieved by addressing the fax as follows:


Example: John.ABC.Smith.Sales.3544254<>

For the alias method to work, you need to confirm that GFI FaxMaker is set to use this method. Proceed as follows:

  1. Open Registry Editor (Start -> Run -> Regedit)
  2. Browse to: 
  • for x86 bit platform: [HKEY_LOCAL_MACHINE\SOFTWARE\GFI Fax & Voice\FaxMaker\Config\E2FG]
  • for x64 bit platform: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\GFI Fax & Voice\FaxMaker\Config\E2FG]
  1. Locate the DWORD value: aliasatserver
  2. Ensure that the Value data for aliasatserver is set to 0. Example: aliasatserver = 0
  3. Restart the GFI FaxMaker Message Transfer Agent Service

This method of sending is supported by most email clients.


  • Information on how to change delimiters when addressing the fax can be found in the knowledge base article here
  • If the registry key [HKEY_LOCAL_MACHINE\SOFTWARE\GFI Fax & Voice\FaxMaker\Config\E2FG/aliasatserver] is set to 1 and the alias method is used, the user sending the fax using this method will get the following error: No recipients were found in this message. Fax could not be sent.
  • Some email clients do not fully support the email address alias. In this case another fax sending method needs to be used. Other fax sending methods are documented at here
