I started writing this for new people to get into FreeBSD, and learn how it works. I think it's a pretty simple article, and it takes it slow and easy for newer people getting involved with Unix. It's the first article in a series I'm writing entitled 'Beginners Guide To FreeBSD'.
This small HowTo will show you how to set up a full-featured mail server on NetBSD 1.6.2 with Exim and Teapop. We will replace the default MTA on NetBSD, Sendmail with Exim from pkgsrc, configure it with smtp authentication and also install Teapop to provide POP3 access to our mails. Both server will be configured to authenticate local users not against the system password file, but a standalone mail authentication file based on the htpasswd format.
