For anyone still using Courier, I'd highly recommend giving Dovecot a
try.  Being a Courier user for years I finally gave Dovecot a chance
when I setup my last mailserver and I've never looked back.  Better
security, vastly superior speed and memory footprint and drop dead easy
setup for IMAP/s and POP3/s..
