Wait... I thought to just try something and changed
cyrus     unix  -       -       n       -       -       lmtp

to

cyrus     unix  -       n       n       -       -       lmtp

and the mail delivered just fine to the proper INBOXes.  If I may ask
why making the unpriv to no made it work?  It was the combination of
things that made it work from all the suggestions and help.  I have
included the whole master.cf file.  I would love some help to understand
why this worked and why the other attempts did not work.
