What kind of loads are you seeing, i.e., how many concurrent 
connections per second at what CPU utilization? How much 
memory does the process utilize?

At my previous employer, we were happy with Courier's POP3d 
daemon. It supports virtual domains reading data off a MySQL 
database that provides the location to customers' Maildir 
directories in addition to authentication data.

Mail is delivered to the customers' mailboxes via Exim.

Courier (both POP3 and IMAP) can be configured with the number 
of concurrent connections to accept. We started off with 40 
(default) but had increased to 200 within 3 months without 
any issues on the box.

Cheers,

Mark.
