nullmailer is equivalent to a submit-only mail server;
you can run a unix system without mail;
but it is very handy at times.

Most of my servers send me security reports and exception reports for the services they are running.

You can look in /var/spool/nullmailer/queue for the actual messages to
see what is carping.

That helps!  Cron is having trouble.  I've set up a personal cron
to run every minute.  It runs a script which decides which other
things need to be run.  It in turn depends on /etc/profile being
right, and I haven't fixed that from the default Ubuntu provides.
I will fix that now.  Thank you.

Also look in /etc/nullmailer/remotes to see where it wants to send mail.
Chances are the host is either wrong or non-existent.

It says "mail."  Seems pretty useless.  And there is no man page
or info page for nullmailer.  I think software without a man page
should be banned from the distribution.  But maybe that's just me.

Scanning the net it sounds like nullmailer is for systems which
always can talk to a smart mail server.  I don't that applies here.
OTOH I'm not sure I want the system to be doing anything with mail.
So perhaps the answer is simply to remove nullmailer from the system.
Of course that would mean I wouldn't get debug info from cron.
