This howto focuses on a fast deployment of secure (APOP) Qpopper email pop3 server.

This howto is just a scratch, and does not want to be complete nor faultless.

1. install qpopper
   sudo apt-get install qpopper
2. open /etc/inetd.conf and add
   pop-3 stream tcp nowait root [or other user] /usr/sbin/tcpd /usr/sbin/in.qpopper -f /etc/qpopper.conf
3. edit configuration file /etc/qpopper.conf according to your needs
4. create a pop3 user with
   touch /var/spool/pop/.[username].pop
   and grant user permissions via
   chmod u=rw .[username].pop
5. set secure authentication
   set line set-clear-text-password in /etc/qpopper.conf to SSL or TLS (preferrred)
6. reload inetd
   sudo /etc/init.d/indetd force-reload
7. if you see this error
   pop authentcation db not available
   create an APOP database with command
   popauth -init
8. add a record with user username and password
   popauth -user [username] [password]
9. enable on the mail client the “use secure authentication” option
