Now I'm wanting to use it for my company, which has 100+ users who each has a mailbox of 500+ megs :-( - so I'm ofcourse worried about performance.

I've read several people saying that cyrus imapd implements caching of the maildir listings, which in turn gives a great performance boost especially when the user has a lot of Email (which me and the other users do).

Did you also read anyone mentioning the little fact that most IMAP clients -- namely Mozilla and MSOE -- cache IMAP mail headers themselves, so they never end up requesting the same set of headers the second time; and any kind of caching done by the server ends up to be a big waste of time?

Is this caching in courier-imaps future? or can I do something to

No. It's a complete waste of time.

Also I would like to use ldap as authentication for courier-imap users. Is this cached or can I do anything to implement this? I guess this should be done serverside - on the ldap server?

authdaemon connects to the ldap server at startup and maintains a persistent connection, for all authentication requests.
