To what remote server? The log entry above shows "her" PC connecting to 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. -- Stan
