wu-imapd is not very high performance.  As a matter of fact RHEL4 
doesn't ship imapd, it ships Dovecot and Cyrus.  Strongly recommend you 
take a look at Courier-IMAP, Dovecot or Cyrus.  I'm quite happy with 
Courier-IMAP on RHEL4.  I think it's the best solution but since it 
doesn't support mbox storage, I believe RH had to use Dovecot which 
supports Maildir and mbox.  But once you convert your mbox accounts over 
to Maildir, everything pretty easy.
