Of course xinetd offers a lot of options to limit resource usage, so I suspect 
it might be the method of choice under load, especially if you use it to 
manage all the other mail related daemons on the server.

I'm curious are there any main stream IMAP/POP3 servers not using the "process 
per user" or "thread per user" model? As I wrote a proof of concept server 
using Java NBIO, for another application once, the idea being to implement a 
"staged event driven" architecture - but alas it didn't attract much 
interest. As this would presumably be the smart way to handle high load if 
context switching became the bottleneck.
