554 5.7.1 This message has been blocked because the return email domain is invalid.(domain name has invalid syntax)
Googled web pages suggest that the problem is a bad envelope sender. In the case above the domain appears to be a blank. Is the sender just 'user' instead of '[email protected]'? It's not a Mimedefang error.
