Благодарю вас osorkon. Я сделал ставку на Dovecot , а вот как в  virtual_mailbox_maps указать , что пользователи в системе ? Машина у меня в домене , и соответственно каким-то образом можно заставить Postfix брать пользователей из системы ,  Читал руководство по Postfix Ральфа Гильдебранта , но там рассказывается как указать в virtual_mailbox_maps путь к файлу с пользователями.

Закончил связку , а толку мало , telnet -ом слушаются и Dovecot и Postfix  , а если отсылаю сообщение пользователю с другой почты , то оно не приходит , прошу помочь найти ошибку. 

Настроил POSTFIX
postconf -n

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
inet_interfaces = all

myhostname = postman.domen.ru
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost =
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)

smtpd_use_tls = yes
virtual_mailbox_base = /var/mail
virtual_mailbox_domains = domain.ru

Подогнал Dovecot

Привел Dovecot к такому виду :
protocols = imap imaps
listen = *
log_path = /var/log/dovecot/dovecot.log
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/var/mail/%u
   

 
mail_privileged_group = mail
mail_debug = yes
protocol imap {

В логах пусто
А  при перезагрузке пишет:

.
Запускаю как Dovecot -F
If you have trouble with authentication failures,
enable auth_debug setting. See http://wiki.dovecot.org/WhyDoesItNotWork

Postfix на всякий случай , он работает нормально письма при телент раскладывает по Maildir

У меня в конфиге достаточно указать  auth_debug = yes и он все в логи кидает , это булевый параметр (вовсяком случае у меня)

давайте тогда вывод doveconf -nm auth, doveconf -nm imap, doveconf -nm imap-login

Oscor нет у меня такого пакета ....(

Не хотелось бы dovecot2 ставить пока этот толком не освоил
Вот мой конфиг:

listen = *
log_path = /var/log/dovecot/dovecot.log
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/var/mail/%u
   # Hierarchy separator to use. You should use the same separator for all
   # namespaces or some clients get confused. '/' is usually a good one.
   # The default however depends on the underlying mail storage format.
   #separator =
   # Prefix required to access this namespace. This needs to be different for
   # all namespaces. For example "Public/".
   #prefix =
   # Physical location of the mailbox. This is in same format as
   # mail_location, which is also the default for it.
   #location =
   # There can be only one INBOX, and this setting defines which namespace
   # has it.
   #inbox = no
   # If namespace is hidden, it's not advertised to clients via NAMESPACE
   # extension. You'll most likely also want to set list=no. This is mostly
   # useful when converting from another server with different namespaces which
   # you want to deprecate but still keep working. For example you can create
   # hidden namespaces with prefixes "~/mail/", "~%u/mail/" and "mail/".
   #hidden = yes
   # Show the mailboxes under this namespace with LIST command. This makes the
   # namespace visible for clients that don't support NAMESPACE extension.
   # "children" value lists child mailboxes, but hides the namespace prefix.
   #list = yes
   # Namespace handles its own subscriptions. If set to "no", the parent
   # namespace handles them (empty prefix should always have this as "yes")
   #subscriptions = yes
   #separator = /
   # Mailboxes are visible under "shared/user@domain/"
   # %%n, %%d and %%u are expanded to the destination user.
   #prefix = shared/%%u/
   # Mail location for other users' mailboxes. Note that %variables and ~/
   # expands to the logged in user's data. %%n, %%d, %%u and %%h expand to the
   # destination user's data.
   #location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u
   # Use the default namespace for saving subscriptions.
   #subscriptions = no
   # List the shared/ namespace only if there are visible shared mailboxes.
   #list = children
mail_privileged_group = mail
mail_debug = yes
protocol imap {

  # This would attach gdb into the imap process and write backtraces into

Я так понимаю если пользователи у меня локальные так как Машина в Домене ,то и авторизация должна быть PAM ?
Уважаемый osorkon целиком dovecot.conf сюда не влезет

попробуйте в сполер запихнуть, может влезет. если нет тогда не знаю

http://pastebin.com/VDStk2z9  тут он

l_cho не надоело сообщения без тегов писать? Многие такие посты просто не читают...
