I considered that but I cannot be sure that there will just be one
group.  I am trying to recreate a public folder structure that is
being used fro work flow management and is implemented using Exchange.
 Right now every user in the company has read/write access to every
public folder and I was told to change that on the IMAP server so
there may be two or three different groups.  To be honest I am not
very optimistic about the prognosis since I have to use Outlook as the
IMAP client.

No matter, that -- Even if the project here flops I know enough now
that I can migrate other clients from courier to dovecot when the time
comes.  That alone made the time worth it.
