Flame War! -- IMAP Servers

[Empty]

I am a huge fan of courier, but I have heard a lot about Cyrus that is
interesting.

One thing you might be having trouble with is less about the name of the
server you are running and more about some of your backend
considerations. Where is mail stored(NFS, local raid, IDE disk, etc)?
How is it stored (mbox? Maildir?)

Hell, even Exchange can run that many users on that hardware- something
is clearly awry.
