 I will be using the simple //sendmail// service that comes as standard with BSD installations. It just needs to be configured and started. I don't need any clever security, as it can only be accessed from the LAN, and I'm not going to tell it how to pass messages on to the outside world.

 . Tell sendmail where to deliver root's mail to.
-Node: You can't log in as root to pick up your mail - that would be dangerous, because the mail system would have to run as root to access the files containing the mail. If there's any bugs in the mail server or its helper files, that could result in serious problems! So we need to direct all mail for root into another mailbox that we can access as an unprivileged user.

 I need to be able to view messages on my workstation using a normal mail reader. The messages I receive will be actioned and then deleted. I don't need the clever folders that IMAP provides, so I'll just use the POP protocol to access the mailbox.
-Initially I just want one mailbox for all notifications from the various devices across my LAN. This can easily be configured by creating a normal Unix user on the mail server box. They don't need to be able to log in, but the normal passwd and shadow files will store all the configuration we need for each mailbox. The root login and other system logins will be set to forward their mail to my special email address on the same host.
+I will be using the //qpopper// service to provide simple POP mailbox access.
+. Install the software
+<code>
+jexec "ioc-${JAIL_NAME:?}" pkg install qpopper
+</code>
+. Configure the service.
+<code>
+jexec "ioc-${JAIL_NAME:?}" vi /etc/inetd.conf
