Use the queue id to correlate log entries for a single message. That'll
let you obtain statistics for delivered and rejected messages. Bounces are
another thing -- there is no way for Postfix to know that a particular
bounce message is for a specific message that Postfix has sent. What you
can do is use VERP to at least identify which recipient addresses lead to
bounces.
