[Dovecot] shared folder

[Eric Broch]

  Hello list,

I have dovecot-1.2.3 installed on my mail server. I created a shared 
directory which works fine, however, this shared directory has over 16GB 
of email and when users, 40 to 50 of them, login to their IMAP account 
and download of the contents of this shared folder begins on their 
machines it bogs down the server to a crawl. I had to comment out the 
share it was so bad. Is there a way to implement permissions on the 
shared folder and add 1 or 2 users at a time so as not to bog down the 
server.
