Courier-imap & squirrelmail: Maildir structure problem.

[stevan@ojingo.net (Stevan Kanban)]

Hello,

I've got a webmail server based upon a courier-imap (& courier-imap-ssl) server and an apache2 that redirects on the Squirrelmail 
php pages. Everything is OK except i cannot get the Maildir structure i want (By tuning parameters in the different configuration 
files, i have many structures except the one i wish) as described following:

<mail_user_root>/<domains_folder>
			<account_folder>
				Maildir/
					inbox/
						cur/
						new/
						tmp/
					sent-mail/
						cur/
						new/
						tmp/
					trash/
						cur/
						new/
						tmp/
					drafts/
						cur/
						new/
						tmp/

So, this is the structure i want to use for my virtual accounts. My system accounts are already organized according to a such 
structure.

My question: how should i configure imap and squirrelmail to obtain this?

My configuration files are:

+ /etc/courier-imap & /etc/courier-imap-ssl:

# INBOX.Outbox
#
# OUTBOX=.Outbox

MAILDIRPATH=Maildir

Note: I don't know the meaning of the two commented parameters. Concerning the third one, i cannot get its behavior too.

+ /etc/userdb/<domains_file>

account    pop3pw=cryptpass|imappw=cryptpass|uid=mail_user_uid|mail=<mail_user_root>/<domains_folder>/<account_folder>/Maildir/|home=<mail_user_home>|gid=65534

+ /etc/squirrelmail/config.php

$domain                 = trim(implode('', file('/etc/'.(file_exists('/etc/mailname')?'mail':'host').'name')));
$imapServerAddress      = 'localhost';
$imapPort               = 143;
$useSendmail            = false;
$smtpServerAddress      = 'localhost';
$smtpPort               = 25;
$sendmail_path          = '/usr/sbin/sendmail';
$pop_before_smtp        = false;
$imap_server_type       = 'courier';
$invert_time            = false;
$optional_delimiter     = '.';

$default_folder_prefix          = 'INBOX.';
$trash_folder                   = 'trash';
$sent_folder                    = 'sent-mail';
$draft_folder                   = 'drafts';
$default_move_to_trash          = true;
$default_move_to_sent           = true;
$default_save_as_draft          = true;
$show_prefix_option             = false;
$list_special_folders_first     = true;
$use_special_folder_color       = true;
$auto_expunge                   = true;
$default_sub_of_inbox           = false;
$show_contain_subfolders_option = false;
$default_unseen_notify          = 2;
$default_unseen_type            = 1;


+ /etc/squirrelmail/config_default.php

$trash_folder = 'INBOX.Trash';
$sent_folder  = 'INBOX.Sent';
$draft_folder = 'INBOX.Drafts';
$auto_expunge = true;
$delete_folder = false;

Note: it's the installation default configuration file. Until now i don't dare to change it and i would do if necessary only.


I would like the one who answer tries to do this didactly because there's no many infos about this topic on google.

Thanks a lot,
