CDO Error

Possible Solutions

The transport failed to connect to the server.

Connection with the mail server couldn’t be established. Confirm the following settings:

  • IP address of the mail server.
  • Secure connection (encryption) settings.
  • Check if firewall is blocking connection between GFI FaxMaker and the mail server.

The server rejected one or more recipient addresses. The server response was: 550 5.7.1 Unable to relay for <email address>

Connection with mail server was established but mail server refused the domain of the recipients address.

This normally occurs because relaying is not allowed from the GFI FaxMaker server. Configure SMTPSimple Mail Transport Protocol server to accept relaying from the GFI FaxMaker machine's IP or allow relaying for the internal email domain only.

The server rejected the sender address. The server response was: 530 5.7.3 Client was not authenticated.

GFI FaxMaker can connect with mail server but user authentication details are missing. Select Use SMTP Authentication and key in credentials.

The message could not be sent to the SMTP server. The transport error code was 0x80040217. The server response was not available

GFI FaxMaker can connect with mail server but user authentication details are invalid. Check credentials.
