email IMAP

[R12y]

Hi,
I cant find a suitable configuration to check my IMAP account on a
remote server.
This is my directory structure:

mihamina-mfc>>>>pwd
/home/mihamina/Maildir
mihamina-mfc>>>>ls -la
total 1572
drwx------  128 mihamina mihamina   4096 Jun  1 03:40 .
drwx------   14 mihamina mihamina   4096 Jun  1 03:41 ..
drwx------    6 mihamina mihamina   4096 Jul 12  2005 .asa
drwx------    5 mihamina mihamina   4096 May 31 18:49 .asa.adventiste

I use Dovecot on this server.
Evolution and thunderbird can fetch the messages without any problem.
I dont even have the IMAP "folder" list on Gnus.
I can access usenet without problem.
Here is what is in my .gnus.el:

(setq gnus-select-methods
      '(
        
        (nnimap "RKTMB"
                (nnimap-server-port 143)
                (nnimap-address "mfc.rktmb.org")
                (nnimap-list-pattern ("INBOX" "Maildir/.INBOX"))
                )
        
        ))

Although I suppress 

               (nnimap-list-pattern ("INBOX" "Maildir/.INBOX"))

I cant get the directory listing...
Would you help me?
