Title: checkpasswd install How-To
Subject: use non-system accounts for your email accounts.

Qmail can use user accounts that are not system accounts. 
To do this I have used vpopmail for user accounts and checkpassword.
This is the setup for checkpassword

vi /etc/hosts.allow
tcp-env: 192.168.0.12, 63.195.58.123: setenv = RELAYCLIENT

read the /var/qmail/doc/FAQ
	search for pop3
$ su
Password: 
# mkdir /usr/local/download 
# mv checkpassword-0.81.tar.gz /usr/local/download

# tar -xzpf checkpassword-0.81.tar.gz 
# make
# make setup check
./install
./instcheck
