Dear list,
Please see below for the follow up. I accidentally only replied to Greg
in my previous response. I am glad to report that this issue is now
resolved.
Thanks!

Thank you again for staying with me.
I installed nut via pkg in FreeBSD 14.3-RELEASE. It is 2.8.2_1 version that is
installed.
One thing I tried last night was trying su with the -m as you suggested below,
and I got this:
# su -m nut -c '/usr/local/bin/mailme baz bar foo'
su: /usr/local/bin/mailme: Permission denied
It is weird, because /usr/local/bin/mailme has permissions set at 755, although
owned by the root. It was actually a symlink to /root/scripts/mailme.sh which
has the same permissions set at 755; however, since the /root directory's
permissions are 750, I thought it created the problem. Therefore, I unlinked
the symlink and copied the script under /usr/local/bin/mailme instead. Then,
the following worked:
# su -m nut /usr/local/bin/mailme foo baz bar
I tried the power outage simulation again after this, and I am happy to report
that I now get emails from the UPS regarding the events, at least on battery
and online ones that I tested so far.
Thank you so much for your help and time!

I did, a few times, but I suspect what I get from that is not what you get when
we read it.
