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 }
