This is amusing.  First, it's unclear to me why your system is
set up so that UNPRIVELEDGED users can grab control of the resources
required to make these systems programs work.  Generally programs need
to be running as root to make this work.  Programs should generally not
be setuid root when they are going to be started from rc, as rc is
executed as root to begin with.

sendmail is a sticky problem.  For some harebrained reason sendmail is
setuid root on BSD systems and will allow you to use set daemon mode
even if you are only effectively root.  Oh well.
