It could be your hardware or filesystem.
Check the load of your server when accessing your mailbox, is there a  
proc eating the CUP or is it doing nothing ?


Here, we use courier-imap 4.3. Maildirs are stored on a RAID5(PERC  
5/i) disk (ext3).
We don't have many users here, but all of them have thousands of  
emails (too many!) in their mailbox (Some of them still don't (or  
don't want to) know that they can create sub-folders :-()

I've just tried sorting by date/thread/... folders containing about  
5000 emails and it took less than 5 seconds. The first access to the  
folder takes about 10s though.

The hook _imp_hook_msglist_format is also enabled, so courier-imap has  
to read every emails.
