That is strange. I have never seen a case where mail is delivered to postfix and disappeared without trace in logs. Do the following basic checks 1) Make sure the process running smtpd is postfix. for eg lsof -i tcp:25 2) On the receiving server start postfix smtpd in debug mode and follow the logs for the IP of the sending server. 3) On the sending server you would be getting maillogs with "ok queued as XXXXXXX". That will give you the queue-id of the mail which you can look for
