At least what they used to do is use MMDF to deliver the inbound mail to a `puntmail' queue. This seemed to be a per-machine (you got mail for an entire machine, not just one account) queueing system. When you logged on, you got the mail `punted' to you by some automated trigger. Mail that arrived while you are online was periodically delivered, presumably in some round-robin system done in the `idle' time between login-delivery requests. I'm surprised they're still using it ... they musta done some serious hacking to make it scalable to 80k+ `machines'.
