Storing email in the home directory of the "root" user is a poor choice.
Store the email in a suitable directory under /var/spool/, and for a
user other than root.
noc: "|/usr/local/sbin/rtmailgate ops noc cor", noc-archive
Create a noc-archive user, and arrange for that user's email to be
delivered to a maildir.

Good, the home directory should belong to root only and not allow access
by others.

Not a good idea.

No. Leave "root" out of the delivery path for mail.
