Have you tried qmailanalog?
http://pobox.com/~djb/qmailanalog.html
It gives _among others_:
the time spent by a message in the queue,
the latency for a delivery attempt,
latency for a successful delivery to one recipient,
the first pct% of successful deliveries all happened within doneby secs,
the number of messages sent by the sender,
the number of bytes sent by the sender,
the number of bytes successfully received from the sender,
the number of bytes from the sender, weighted by recipient,
the number of delivery attempts (success, failure, deferral)
the number of recipients (success plus failure),
the number of bytes successfully delivered to the recipient,
the number of messages sent to the recipient (success plus failure),
the number of bytes successfully delivered to the given host,
the number of messages sent to the given host (success plus failure)
