[Dovecot] Shared folder doesn't work!

[Brian Lavender]

I can't seem to get a shared folder working properly. I am authenticating
using pam, and the users have a shell account on the system. Problem is,
the permissions on the messages moved into the folder don't maintain
properly, and other users can't read the share.

I have the following in /etc/dovecot/dovecot.conf

namespace public {
  separator = /
  prefix = Public/
  location = maildir:/var/mail/public
}

# If you create a "namespace public" section, then you need to create
# a "namespace private" section
namespace private {
   separator = /
   prefix =
   location = maildir:/home/%u/Maildir
   # There can be only one INBOX, and this setting defines
   # which namespace has it.
   inbox = yes
}

umask = 0007

I am running rc15 from backports on Debian stable.


dovecot (1.0.rc15-1~bpo1) sarge-backports; urgency=low

  * Rebuilt for sarge.
  * Only changes needed were build dependency on libpq-dev changed back to
    postgresql-dev, libmysqlclient15-dev changed back to libmysqlclient12-dev,
    kernel-headers versioned build-dependency removed and debhelper version
    relaxed to 4.

And here is the share. Two users are accessing it: brian and fred which
are both in the colab group. See how the one message doesn't have group
read or write.
