[Dovecot] Dovecot and Phpgroupware compatibility

[Carlos Xavier]

Hi,
I am resending this email, since the fist one didn't hit the list.
Recently we moved our server from mbox format to Maildir format and started 
using Dovecot.
Almost all the users are very happy with this, since the speed had increased 
very much.
I used mb2md to do the conversion and on this task all the mailboxes that 
had "." (dot)
on their names were converted to "_".

But there is one issue with this, we also use the webmail that comes with 
Phpgroupware,
and it uses some mailbox that have fixed named like INBOX.Sent, INBOX.Draft 
and so on.
When their names were changed the sent messages didn't get saved anymore, so 
I had to move
them back to the old names.

After that the sent messages returned to be saved again, but another trouble 
showed up.
As they start with .INBOX and have "." on the names, Dovecot shown them as a 
subdirectory
of the INBOX and we got some people upset with this.

I need help on configuring Dovecot to not show them this way, because if you 
reed the .INBOX.Sent
either on the webmail or by Outlook, the field displayed is the sender, 
witch is not desired.

When I did the conversion, to keep the compatibility with the old server 
(quota, avoid I/O bottleneck, etc), I set
two Maildirs, one at /var/spool/mail/$USER, to be the INBOX and another at 
the user home.

We are using Dovecot version 1.1.13, and below is the relevant configuration 
on use.

namespace public {
   prefix = "#mbox/"
   separator = /
   inbox = yes
   list = no
   location= maildir:/var/spool/mail/%u/:CONTROL=~/control:INDEX=~/control
}

namespace private {
   separator = /
   prefix =
   location= maildir:~/Maildir/:CONTROL=~/control:INDEX=~/control
   inbox = no
}

Best Regards,
Carlos Xavier.
