I read it over 2-3 weeks. The exim config file is easy to understand *after*
you've read enough about it, which probably applies to most other MTAs too.

You can set it up so that fetchmail polls for incoming mail from one pop3 account
at the ISP and passes it to exim via smtp/inetd on port 25. Exim then routes the
mail to each users mail box. These in-boxes may be in /var/mail/$USER on the mail
machine, or on the the users machines. Exim is commonly called using a sendmail
command from a MUA when sending mail. Debian defaults to exim and is easy to set
up (after you've done it once or twice.
