I have a brand new NetBSD setup, 2.0_BETA.  To make sure this problem 
hadn't been fixed, I just yesterday updated my sources via CVS, and 
installed with the standard...build.sh distribution; build.sh install=/

I get no emails send to root from the daily or security secripts, or 
when cron fails a job.  /var/log/maillog is full of the following:
--------------------------------------------

I see that this issue has been discussed before on the mailing list, 
mostly sometime in 2003, but I cannot find a direct answer (it is mostly 
ranting, arguing, and patches for dirty hacks)

Why is sendmail configured wrong on a fresh install?  How do I get this 
working?  All I want is to recieve output from daily and security 
scripts and nothing more.  I don't want to run sendmail or any other 
MTA.  1.6.2 had no trouble with this...It worked out of the box with no 
configuration needed.
