If the message cannot be delivered by the SMTP server, it will send a bounce message to the sender. To easily detect those bounces the standard technique is Variable Envelope Return Path Address (VERP) and it is supported by Postfix: http://www.postfix.org/VERP_README.html What you need to do is to direct the bounce messages to a mechanism that detects the bounces and act accordingly on your system. Email is an asynchronous communication, therefore there is little hope to have feedback at submission time about the delivery of a message. Cheers, Daniele
