your Postfix server, and being rejected, because your Postfix server is
configured to reject_non_fqdn_helo_hostname. Your Postfix server never
connects to a server at the remote domain. It's rejecting her mail, period.
You should not be allowing this type of relay from consumer broadband
connected PCs anyway. That's what SMTP SASL AUTH and the submission
service. Read the Postfix docs regarding submission service and SASL AUTH.
