Fedora does not have a mailadm group, or at least did not when I
installed
this system, but this was yet another good clue.

I played around with mtest in the c-client package somemore and found
that Dovecot does not permit root logons period.  So I added a basic
Unprivilaged account and set the authuser/authpassword in voicemail.conf
to use that account.  Now it works, except maybe the expunge bit, which
is likely a config issue.

Thanks to everyone for the help.  I'm looking forward to some of the
IMAP
enhancements listed in the bugtracker.  My mother-in-law has an
extension
on my system, but no mailbox, so I would love to have her extension use
legacy VM and my wife and I get the new IMAP storage.
