  # Password database is used to verify user's password (and nothing more).

  #
  # <doc/wiki/PasswordDatabase.txt>
  #
  # By adding master=yes setting inside a passdb you make the passdb a list
  # of "master users", who can log in as anyone else. Unless you're using PAM,
  # you probably still want the destination user to be looked up from passdb
  # that it really exists. This can be done by adding pass=yes setting to the
  # master passdb. <doc/wiki/Authentication.MasterUsers.txt>

  # Users can be temporarily disabled by adding a passdb with deny=yes.
  # If the user is found from that database, authentication will fail.
  # The deny passdb should always be specified before others, so it gets

  #passdb passwd-file {
    # File contains a list of usernames, one per line
    #args = /etc/dovecot.deny
    #deny = yes

  # PAM authentication. Preferred nowadays by most systems.
  # Note that PAM can only be used to verify if user's password is correct,
  # so it can't be used as userdb. If you don't want to use a separate user
  # database (passwd usually), you can use static userdb.

    # PAM plugins need this to work, such as pam_mkhomedir.

    # setcred=yes makes Dovecot establish PAM credentials if some PAM plugins
    # need that. They aren't ever deleted though, so this isn't enabled by
    # default.
    #
    # max_requests specifies how many PAM lookups to do in one process before
    # recreating the process. The default is 100, because many PAM plugins
    # leak memory.
    #
    # cache_key can be used to enable authentication caching for PAM
    # (auth_cache_size also needs to be set). It isn't enabled by default
    # because PAM modules can do all kinds of checks besides checking password,
    # such as checking IP address. Dovecot can't know about these checks
    # without some help. cache_key is simply a list of variables (see
    # doc/wiki/Variables.txt) which must match for the cached data to be used.
    # Here are some examples:
    #   %u - Username must match. Probably sufficient for most uses.
    #   %u%r - Username and remote IP address must match.
    #   %u%s - Username and service (ie. IMAP, POP3) must match.
    #
    # The service name can contain variables, for example %Ls expands to
    # pop3 or imap.

    # Some examples:
    #   args = session=yes %Ls
    #   args = cache_key=%u dovecot

  # ACL plugin. vfile backend reads ACLs from "dovecot-acl" file from maildir
  # directory. You can also optionally give a global ACL directory path where
  # ACLs are applied to all users' mailboxes. The global ACL directory contains
  # one file for each mailbox, eg. INBOX or sub.mailbox. cache_secs parameter
  # specifies how many seconds to wait between stat()ing dovecot-acl file
  # to see if it changed.
  #acl = vfile:/etc/dovecot-acls:cache_secs=300

  # To let users LIST mailboxes shared by other users, Dovecot needs a
  # shared mailbox dictionary. For example:
  #acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes

  # Convert plugin. If set, specifies the source storage path which is
  # converted to destination storage (mail_location) when the user logs in.
  # The existing mail directory is renamed to <dir>-converted.
  #convert_mail = mbox:%h/mail
  # Skip mailboxes which we can't open successfully instead of aborting.
  #convert_skip_broken_mailboxes = no
  # Skip directories beginning with '.'
  #convert_skip_dotdirs = no
  # If source storage has mailbox names with destination storage's hierarchy
  # separators, replace them with this character.
  #convert_alt_hierarchy_char = _

  # Trash plugin. When saving a message would make user go over quota, this
  # plugin automatically deletes the oldest mails from configured mailboxes
  # until the message can be saved within quota limits. The configuration file
  # is a text file where each line is in format: <priority> <mailbox name>
  # Mails are first deleted in lowest -> highest priority number order
  #trash = /etc/dovecot-trash.conf

  # Expire plugin. Mails are expunged from mailboxes after being there the
  # configurable time. The first expiration date for each mailbox is stored in
  # a dictionary so it can be quickly determined which mailboxes contain
  # expired mails. The actual expunging is done in a nightly cronjob, which
  # you must set up:
  #   dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool
  #expire = Trash 7 Spam 30
  #expire_dict = proxy::expire

  # Lazy expunge plugin. Currently works only with maildirs. When a user
  # expunges mails, the mails are moved to a mailbox in another namespace
  # (1st). When a mailbox is deleted, the mailbox is moved to another namespace
  # (2nd) as well. Also if the deleted mailbox had any expunged messages,
  # they're moved to a 3rd namespace. The mails won't be counted in quota,
  # and they're not deleted automatically (use a cronjob or something).
  #lazy_expunge = .EXPUNGED/ .DELETED/ .DELETED/.EXPUNGED/

  # Events to log. Also available: flag_change append
  #mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename
  # Group events within a transaction to one line.
  #mail_log_group_events = no
  # Available fields: uid, box, msgid, from, subject, size, vsize, flags
  # size and vsize are available only for expunge and copy events.
  #mail_log_fields = uid box msgid size

  # Sieve plugin (http://wiki.dovecot.org/LDA/Sieve) and ManageSieve service
  #
  # Location of the active script. When ManageSieve is used this is actually
  # a symlink pointing to the active script in the sieve storage directory.

  # The path to the directory where the personal Sieve scripts are stored. For
  # ManageSieve this is where the uploaded scripts are stored.

thanks for answer till, i thought about this, but i did install all by yum. using perfect server guide.

here's the output :

[CODE
[root@ocsinet install]# uname -a
Linux ocsinet.local 2.6.18-308.1.1.el5 #1 SMP Wed Mar 7 04:16:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux
[root@ocsinet install]#][/CODE]

 

in any case, do you have a solution for this? i did try to reinstall all , then update ispconfig, nothing...
