Does that system run the /etc/periodic system scripts? If yes,
where does the output go?
The only thing that sendmail requires for delivering local mail
(i. e., from "process user" to "real user" and of course for
"real user" to "real user") is a correct configuration for the
loopback device (see 127.0.0.1 and localhost). So if you have
in your /etc/hosts, it should be okay. The setting
in /etc/rc.conf should be sufficient. This makes sure that
the periodic scripts can send messages to root (or any other
user, if additionally specified), as well as "intra-system
communication", such as:
% mail root
Subject: A test
This is a test.
And into the other direction:
# mail -s "Test works" bob
the test was successful.
This is basic system functionality. ;-)
See /etc/defaults/rc.conf for sendmail-related items.
