This is a neat thread, because at this point (a big pile of queues) the work needed to throw the whole thing into a database is trivial. Chuq, Apple's EOF would let you build a Mailman analog in under an hour, btw! Faster and easier to maintain!

I was kinda thinking the same thing -- you start looking in terms of messages and semaphores instead of a real queue manager. And instead of moving messages among queues, you simply pass a token around from place to place until mailman is done with it...

Percisely. However we need to maintain the abstraction of Mailman from its underlieing queue implementation, be it really implemented by something like MQS, just index twiddles in an SQL DB, or movelments of files among specially named/located directories. If we keep the queue model and just provide plugins for the (few) queue manipulation points -- which really just sumes to "move message X from queueA to queueB -- then we pretty well get the rest for free.

Doing this in a decent database becomes really interesting (in a fun way, not in a grind your teeth way)

True.
