Hi,
we have similar setup like Thierry, but not so big. Only 40k users and
1,2T of used space. Only 300 concurrent POP3 and 1600 IMAP sessions.
Imap is increasing continously.
Due to the fact that we have a low budget we impelented the following
small solution.
- 2 static IMAP/POP3 Proxies

I believe a variation on that theme is also to "double" each machine
using DRBD so that machines are arranged in pairs. One can fail and the
other will take over the load. ie each pair of machines mirrors the
storage for the other. With this arrangement only warm failover is

Managing a mail system for 1M odd users, we did run for a few years on some
high range SAN system (NetApp, then EMC), but were not happy with the
performance, whatever double head, fibre, and so on, it just couldn't handle
the IOs. I must just say that at this time, we were not using
