As Jeff mentioned, UW-IMAP must be your enemy. You may find the high
load is made by imapd processes, with a command like 'top'.

I recently moved from sendmail with UW-IMAP(mbox) to postfix with
Courier-IMAP(maildir) because as my mailbox get bigger my server get
terribly slower. My server's load dropped and my email clients got
much faster, too. I got satisfied a lot.

I recommend you to change your imapd. There are also scripts available
so that your existing mboxes may be converted into maildir format ones
without problem.
