Problems about INBOXes disappear from multiple Gmail accounts with offlineimap and dovecot integration

[Bullone <kulugox@gmail.com>]

Thanks to a lot of people: Now I can use offlineimap to fetch mails from
Gmail to my local laptop, and at least connect to local Dovecot from
gnus.


However there is still at least two problems:
First: I could read all
groups in gnus just EXECPT INBOX of all three gmail accounts. If I try
to enter the INBOX group,"Group nnimap+One:INBOX contains no messages"
is the *Messages* which pops up.

Second: In fact , once there are repeated IMAP directory names in each
accounts(such as INBOX, @WAITING,@TODO...etc) , these directories will
contains no messages. I think this is the same cause of the first
problem.

Third Every IMAP directories appear in different accounts,which
really wastes a lot of disk space.

In fact I feel the dovecot part is the most reasonable problem, however
I have no more idea how to tune it . I have googled and asked from
#dovecot irc channel, but still with no luck.

Could someone help me set it up? Any suggestion will be appreciated.

My environment is: Debian wheezy stable, GNU Emacs 24.3.50.1, Gnus
V5.13, Offlineimap 6.3.4, Dovecot 2.1.7,

Below is  my gnus, offlineimap,and dovecot configuration files
