Well... not that this answers your question directly, but... have you considered just switching to dovecot? The difference in performance is amazing - and that is not an exaggeration.
I have considered it... and that may be the option I am left with if I can't find a decent webmail client. Although, my bit of research showed Courier coming out a little ahead of Dovecot - mostly based on folder polling methods.
Were you using mbox or maildir? I'm not sure what version you were testing or what your methods were, but dovecot's indexes are what make it so fast, and courier-imap doesn't use indexes.
I'm telling you, properly configured, dovecot will blow courier out of the water, and then some, especially on servers with high loads, and especially for those with large mail stores.
In the end, I highly doubt my user base is savvy enough to notice the difference.
Again, properly configured - they will sing your praises.
I need to find a free weekend before I even consider it, and a decent mysql+dovecot guide. :)
I use postfixadmin, but dovecot's wiki is pretty good, and Timo is really quick to update it when it needs it. There are some MySQL HowTos here:
