I do understand, but as I stated fairly clearly I thought "For reasons
of support I cannot upgrade to a later dovecot at this time."

Of course I have a ticket open with RedHat, but I thought I might come
to the source, find out if it's some form of a known bug, and then
perhaps I *could* use that as leverage to get another version
installed.  So the question still stands:

Is this a known bug?  Is maildirsize not NFS safe?

Knowing that would be a huge first step  for me, so thanks in advance
for any assistance.

Best Regards,

I created maildirsize files for each user in the NFS-mounted /var/spool/mail/$USER and everything seemed fine.   I changed mailbox_command to /usr/libexec/dovecot/deliver  in postfix main.cf.  Mail was delivered, quota files updated, all good.
