[Dovecot] mbox problems on CentOS 6

[DT]

Thank you Thomas for opening my eyes on that matter, I fixed that area as bellow and it solved the Postfix problem 100%
 
service auth {
    unix_listener /var/spool/postfix/private/auth  {
        mode = 0600
        user = postfix
        group = postfix
    }
}
 
Now I only have same old issue with Dovecot only:
2011-08-05 07:52:21 imap(contact at mydomain.com): Debug: Effective uid=901, gid=12, home=/vmail/mydomain.com/contact
2011-08-05 07:52:21 imap(contact at mydomain.com): Error: user contact at mydomain.com: Initialization failed: Initializing mail storage from mail_location setting failed: Unknown mail storage driver maildir
2011-08-05 07:52:21 imap(contact at mydomain.com): Error: Invalid user settings. Refer to server log for more information.
 
Somehow it doesnt like what I have in mail_location or so... but I tried so many other folders, tried maildir also, error keeps showing, I can login to IMAP but once I do I'm dropped :* BYE Internal error occurred. Refer to server log for more information.
Connection closed by foreign host.
 
Thank you again for any oppinion or advice.
