sm-mta[3487]: SYSERR(root): hash map "Alias0": unsafe map file /etc/mail/aliases.db: World writable directory

Hi
FreeBDS 12.1
I have had the error :-

BSD005 sm-mta[3487]: 05A2BQu2003487: SYSERR(root): hash map "Alias0": unsafe map file /etc/mail/aliases.db: World writable directory

at boot time and no messages from cron for 5 days since I re-ordered rc.conf to a more logical order and I set up NFS V4.

I have fiddled about for 4 days with all sorts of things around domain names and rebuilding aliases and even rebuilding a kernel.
Then I took a big risk and tried
chmod 4755 /
That seems to have solved it. So I make this public.
Was that correct?
Does anyone have other thoughts? Regard Derek

Next thing I need to learn is how to mark this as "Solved"

chmod 4755 /

Those are some really bad permissions. Do NOT set the SUID bit here! chmod 0755 /

As for the /etc/mail directory, what does ls -ld /etc/mail show?
