courierpasswd in use

I little while ago, I posted that I had written a checkpassword style 
program called courierpasswd to authenticate users through Courier's 
authentication modules. Now I've posted a document on my web site that 
describes my mail setup including how I use courierpasswd with Courier 
IMAP and qmail.

If anyone is interested in taking a look at it, it can be found at
