It seems for me that postfix is the most robust on queue management among the three you mentioned. qmail is apt to be blocked when the load is heavy and many destinations are suffering from network problems. The queue management of qmail seems to be naive on heavy load. And sendmail is resource hog when the server has large user base. postfix and qmail are more conservative.
