There is one caveat, though: qmail-send will disassemble multi-recipient posts, i. e. you will get one Postfix message and queue ID per recipient - and Postfix has some VERP support (Mailman, for instance, uses it.) If you can somehow manage to inject outgoing mail directly into Postfix, so that you can bypass qmail-send, that may help quite a bit. If your software talks QMQP for injection into qmail for sending outbound mail, you can make Postfix provide a QMQPd.
