I'm running the latest Courier imap.

While most IMAP clients ( mozilla, outlook ) seem to cache the headers and use cached headers for searches, Eudora seems to be pretty dumb. It caches the headers, but goes to the server for searches. This generates a huge load on the server, especially if the Maildir has a lot of messages. Eventually searches from eudora time out or lock up. Is there a way to prevent IMAP searches from being accepted and force the clients to do all their searches locally ?

Another problem is with Eudora's way of displaying Maildir folders. It always puts Inbox as the top root folder and the other folders as it's subfolders. While other clients may display the same thing, that doesn't affect the funcitonality. In Eudora a search for any subdirectory in Maildir, must for some reason inclide the Inbox, which adds up to the previous problem. Is there a specific namespace I could use to force Eudora into thinking all suddirectories are separate folders not subfolders of inbox ?

thank you all in advance.
