[LUGOS] Outgoing Mails

[Mitja Znidaric]

Zdravo!

Še vedno nisem rešil zadeve 5.7.1.-Relay access denied...... :(

Prilagam dovecot.conf:

## Dovecot configuration file

# If you're in a hurry, see http://wiki.dovecot.org/QuickConfiguration

# "dovecot -n" command gives a clean output of the changed settings. Use it
# instead of copy&pasting this file when posting to the Dovecot mailing
list.

# '#' character and everything after it is treated as comments. Extra spaces
# and tabs are ignored. If you want to use either of these explicitly,
put the
# value inside quotes, eg.: key = "# char and trailing whitespace  "

# Default values are shown for each setting, it's not required to uncomment
# any of the lines.

# Base directory where to store runtime data.
#base_dir = /var/run/dovecot/

# Protocols we want to be serving: imap imaps pop3 pop3s
# If you only want to use dovecot-auth, you can set this to "none".
#protocols = imap imaps pop3 pop3s
protocols = imap pop3

# IP or host address where to listen in for connections. It's not currently
# possible to specify multiple addresses. "*" listens in all IPv4
interfaces.
# "[::]" listens in all IPv6 interfaces, but may also listen in all IPv4
# interfaces depending on the operating system.
#
# If you want to specify ports for each service, you will need to configure
# these settings inside the protocol imap/pop3 { ... } section, so you can
# specify different ports for IMAP/POP3. For example:
#   protocol imap {
#     listen = *:10143
#     ssl_listen = *:10943
#     ..
#   }
#   protocol pop3 {
#     listen = *:10100
#     ..
#   }
listen = [::]
#listen = *

# Disable LOGIN command and all other plaintext authentications unless
# SSL/TLS is used (LOGINDISABLED capability). Note that if the remote IP
# matches the local IP (ie. you're connecting from the same computer), the
# connection is considered secure and plaintext authentication is allowed.
#disable_plaintext_auth = no

# Should all IMAP and POP3 processes be killed when Dovecot master process
# shuts down. Setting this to "no" means that Dovecot can be upgraded
without
# forcing existing client connections to close (although that could also be
# a problem if the upgrade is eg. because of a security fix). This however
# means that after master process has died, the client processes can't write
# to log files anymore.
#shutdown_clients = yes

##
## Logging
##

# Log file to use for error messages, instead of sending them to syslog.
# /dev/stderr can be used to log into stderr.
#log_path =

# Log file to use for informational and debug messages.
# Default is the same as log_path.
#info_log_path =

# Prefix for each line written to log file. % codes are in strftime(3)
# format.
#log_timestamp = "%b %d %H:%M:%S "

# Syslog facility to use if you're logging to syslog. Usually if you don't
# want to use "mail", you'll use local0..local7. Also other standard
# facilities are supported.
#syslog_facility = mail

##
## SSL settings
##

# IP or host address where to listen in for SSL connections. Defaults
# to above if not specified.
#ssl_listen =
ssl_listen =

# Disable SSL/TLS support.
#ssl_disable = no

# PEM encoded X.509 SSL/TLS certificate and private key. They're opened
before
# dropping root privileges, so keep the key file unreadable by anyone but
# root. Included doc/mkcert.sh can be used to easily generate self-signed
# certificate, just make sure to update the domains in dovecot-openssl.cnf
#ssl_cert_file = /etc/pki/dovecot/certs/dovecot.pem

# give it when starting dovecot with -p parameter.

# File containing trusted SSL certificate authorities. Usually not needed.
# The CAfile should contain the CA-certificate(s) followed by the matching
# CRL(s). CRL checking is new in dovecot .rc1
#ssl_ca_file =

# Request client to send a certificate. If you also want to require it, set
# ssl_require_client_cert=yes in auth section.
#ssl_verify_client_cert = no

# How often to regenerate the SSL parameters file. Generation is quite CPU
# intensive operation. The value is in hours, 0 disables regeneration
# entirely.

# SSL ciphers to use
#ssl_cipher_list = ALL:!LOW

# Show protocol level SSL errors.
#verbose_ssl = no

##
## Login processes
##

# <doc/wiki/LoginProcess.txt>

# Directory where authentication process places authentication UNIX sockets
# which login needs to be able to connect to. The sockets are created when
# running as root, so you don't have to worry about permissions. Note that
# everything in this directory is deleted when Dovecot is started.
#login_dir = /var/run/dovecot/login

# chroot login process to the login_dir. Only reason not to do this is
if you
# wish to run the whole Dovecot without roots. <doc/wiki/Rootless.txt>
#login_chroot = yes

# User to use for the login process. Create a completely new user for this,
# and don't use it anywhere else. The user must also belong to a group where
# only it has access, it's used to control access for authentication
process.
# Note that this user is NOT used to access mails. <doc/wiki/UserIds.txt>
#login_user = dovecot

# Set max. process size in megabytes. If you don't use
# login_process_per_connection you might need to grow this.
#login_process_size = 32

# Should each login be processed in it's own process (yes), or should one
# login process be allowed to process multiple connections (no)? Yes is more
# secure, espcially with SSL/TLS enabled. No is faster since there's no need
# to create processes all the time.
#login_process_per_connection = yes

# Number of login processes to keep for listening new connections.
#login_processes_count = 3

# Maximum number of login processes to create. The listening process count
# usually stays at login_processes_count, but when multiple users start
logging
# in at the same time more extra processes are created. To prevent
fork-bombing
# we check only once in a second if new processes should be created - if all
# of them are used at the time, we double their amount until the limit
set by
# this setting is reached.
#login_max_processes_count = 128

# Maximum number of connections allowed per each login process. This setting
# is used only if login_process_per_connection=no. Once the limit is
reached,
# the process notifies master so that it can create a new login process.
# You should make sure that the process has at least
# 16 + login_max_connections * 2 available file descriptors.
#login_max_connections = 256

# Greeting message for clients.
#login_greeting = Dovecot ready.

# Space-separated list of elements we want to log. The elements which have
# a non-empty variable value are joined together to form a comma-separated
# string.
#login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c

# Login log format. %$ contains login_log_format_elements string, %s
contains
# the data we want to log.
#login_log_format = %$: %s

##
## Mailbox locations and namespaces
##

# Location for users' mailboxes. This is the same as the old
default_mail_env
# setting. The default is empty, which means that Dovecot tries to find the
# mailboxes automatically. This won't work if the user doesn't have any mail
# yet, so you should explicitly tell Dovecot the full location.
#
# If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u)
# isn't enough. You'll also need to tell Dovecot where the other
mailboxes are
# and where Dovecot can place its index files. This is called the "root mail
# directory", and it must be the first path given in the mail_location
setting.
#
# There are a few special variables you can use, eg.:
#
#   %u - username
#   %n - user part in user na domain, same as %u if there's no domain
#   %d - domain part in user na domain, empty if there's no domain
#   %h - home directory
#
# See doc/wiki/Variables.txt for full list. Some examples:
#
#   mail_location = maildir:~/Maildir
#   mail_location = mbox:~/mail:INBOX=/var/mail/%u
#   mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
#
# <doc/wiki/MailLocation.txt>
#
#mail_location =

# If you need to set multiple mailbox locations or want to change default
# namespace settings, you can do it by defining namespace sections.
# NOTE: Namespaces currently work ONLY with IMAP! POP3 and LDA currently
ignore
# namespaces completely, they use only the mail_location setting.
#
# You can have private, shared and public namespaces. The only difference
# between them is how Dovecot announces them to client via NAMESPACE
# extension. Shared namespaces are meant for user-owned mailboxes which are
# shared to other users, while public namespaces are for more globally
# accessible mailboxes.
#
# REMEMBER: If you add any namespaces, the default namespace must be added
# explicitly, ie. mail_location does nothing unless you have a namespace
# without a location setting. Default namespace is simply done by having a
# namespace with empty prefix.
#namespace private {
   # 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 = yes

   # If namespace is hidden, it's not advertised to clients via NAMESPACE
   # extension or shown in LIST replies. This is mostly useful when
converting
   # from another server with different namespaces which you want to
depricate
   # but still keep working. For example you can create hidden
namespaces with
   # prefixes "~/mail/", "~%u/mail/" and "mail/".
   #hidden = yes
#}

# Grant access to these extra groups for mail processes. Typical use
would be
# to give "mail" group write access to /var/mail to be able to create
dotlocks.
#mail_extra_groups =

# Allow full filesystem access to clients. There's no access checks
other than
# what the operating system does for the active UID/GID. It works with both
# maildir and mboxes, allowing you to prefix mailboxes names with eg. /path/
# or ~user/.
#mail_full_filesystem_access = no

##
## Mail processes
##

# Enable mail process debugging. This can help you figure out why Dovecot
# isn't finding your mails.
#mail_debug = no

# Log prefix for mail processes. See doc/wiki/Variables.txt for list of
# possible variables you can use.
#mail_log_prefix = "%Us(%u): "

# Max. number of lines a mail process is allowed to log per second
before it's
# throttled. 0 means unlimited. Typically there's no need to change this
# unless you're using mail_log plugin, which may log a lot.
#mail_log_max_lines_per_sec = 10

# Don't use mmap() at all. This is required if you store indexes to shared
# filesystems (NFS or clustered filesystem).
#mmap_disable = no

# Don't write() to mmaped files. This is required for some operating systems
# which use separate caches for them, such as OpenBSD.
#mmap_no_write = no

# Rely on O_EXCL to work when creating dotlock files. The default is to use
# hard linking. O_EXCL makes the dotlocking faster, but it doesn't always
# work with NFS.
#dotlock_use_excl = no

# Don't use fsync() or fdatasync() calls. This makes the performance better
# at the cost of potential data loss if the server (or the file server)
# goes down.
#fsync_disable = no

# Locking method for index files. Alternatives are fcntl, flock and dotlock.
# Dotlocking uses some tricks which may create more disk I/O than other
locking
# methods. NOTE: If you use NFS, remember to change also mmap_disable
setting!
#lock_method = fcntl

# Drop all privileges before exec()ing the mail process. This is mostly
# meant for debugging, otherwise you don't get core dumps. It could be a
small
# security risk if you use single UID for multiple users, as the users could
# ptrace() each others processes then.
#mail_drop_priv_before_exec = no

# Show more verbose process titles (in ps). Currently shows user name and
# IP address. Useful for seeing who are actually using the IMAP processes
# (eg. shared mailboxes or if same uid is used for multiple accounts).
#verbose_proctitle = no

# Valid UID range for users, defaults to 500 and above. This is mostly
# to make sure that users can't log in as daemons or other system users.
# Note that denying root logins is hardcoded to dovecot binary and can't
# be done even if first_valid_uid is set to 0.
#first_valid_uid = 500
#last_valid_uid = 0

# Valid GID range for users, defaults to non-root/wheel. Users having
# non-valid GID as primary group ID aren't allowed to log in. If user
# belongs to supplementary groups with non-valid GIDs, those groups are
# not set.
#first_valid_gid = 1
#last_valid_gid = 0

# Maximum number of running mail processes. When this limit is reached,
# new users aren't allowed to log in.
#max_mail_processes = 1024

# Set max. process size in megabytes. Most of the memory goes to mmap()ing
# files, so it shouldn't harm much even if this limit is set pretty high.
#mail_process_size = 256

# Maximum allowed length for mail keyword name. It's only forced when trying
# to create new keywords.
#mail_max_keyword_length = 50

# ':' separated list of directories under which chrooting is allowed for
mail
# processes (ie. /var/mail will allow chrooting to /var/mail/foo/bar too).
# This setting doesn't affect login_chroot or auth chroot variables.
# WARNING: Never add directories here which local users can modify, that
# may lead to root exploit. Usually this should be done only if you don't
# allow shell access for users. <doc/wiki/Chrooting.txt>
#valid_chroot_dirs =

# Default chroot directory for mail processes. This can be overridden for
# specific users in user database by giving /./ in user's home directory
# (eg. /home/./user chroots into /home). Note that usually there is no real
# need to do chrooting, Dovecot doesn't allow users to access files outside
# their mail directory anyway. <doc/wiki/Chrooting.txt>
#mail_chroot =

##
## Mailbox handling optimizations
##

# Space-separated list of fields to initially save into cache file.
Currently
# these fields are allowed:
#
#  flags, date.sent, date.received, size.virtual, size.physical
#  mime.parts, imap.body, imap.bodystructure
#
# Different IMAP clients work in different ways, so they benefit from
# different cached fields. Some do not benefit from them at all. Caching
more
# than necessary generates useless disk I/O, so you don't want to do that
# either.
#
# Dovecot attempts to automatically figure out what client wants and it
keeps
# only that. However the first few times a mailbox is opened, Dovecot hasn't
# yet figured out what client needs, so it may not perform optimally. If you
# know what fields the majority of your clients need, it may be useful
to set
# these fields by hand. If client doesn't actually use them, Dovecot will
# eventually drop them.
#
# Usually you should just leave this field alone. The potential benefits are
# typically unnoticeable.
#mail_cache_fields =

# Space-separated list of fields that Dovecot should never save to cache
file.
# Useful if you want to save disk space at the cost of more I/O when the
fields
# needed.
#mail_never_cache_fields =

# The minimum number of mails in a mailbox before updates are done to cache
# file. This allows optimizing Dovecot's behavior to do less disk writes at
# the cost of more disk reads.
#mail_cache_min_mail_count = 0

# When IDLE command is running, mailbox is checked once in a while to see if
# there are any new mails or other changes. This setting defines the minimum
# time to wait between those checks. Dovecot is however able to use dnotify
# and inotify with Linux to reply immediately after the change occurs.
#mailbox_idle_check_interval = 30

# Save mails with CR+LF instead of plain LF. This makes sending those mails
# take less CPU, especially with sendfile() syscall with Linux and FreeBSD.
# But it also creates a bit more disk I/O which may just make it slower.
# Also note that if other software reads the mboxes/maildirs, they may
handle
# the extra CRs wrong and cause problems.
#mail_save_crlf = no

##
## Maildir-specific settings
##

# By default LIST command returns all entries in maildir beginning with
a dot.
# Enabling this option makes Dovecot return only entries which are
directories.
# This is done by stat()ing each entry, so it causes more disk I/O.
# (For systems setting struct dirent->d_type, this check is free and it's
# done always regardless of this setting)
#maildir_stat_dirs = no

# When copying a message, do it with hard links whenever possible. This
makes
# the performance much better, and it's unlikely to have any side effects.
#maildir_copy_with_hardlinks = no

# When copying a message, try to preserve the base filename. Only if the
# destination mailbox already contains the same name (ie. the mail is being
# copied there twice), a new name is given. The destination filename
check is
# done only by looking at dovecot-uidlist file, so if something outside
# Dovecot does similar filename preserving copies, you may run into
problems.
# NOTE: This setting requires maildir_copy_with_hardlinks = yes to work.
#maildir_copy_preserve_filename = no

##
## mbox-specific settings
##

# Which locking methods to use for locking mbox. There are four available:
#  dotlock: Create <mailbox>.lock file. This is the oldest and most NFS-safe
#           solution. If you want to use /var/mail/ like directory, the
users
#           will need write access to that directory.
#  fcntl  : Use this if possible. Works with NFS too if lockd is used.
#  flock  : May not exist in all systems. Doesn't work with NFS.
#  lockf  : May not exist in all systems. Doesn't work with NFS.
#
# You can use multiple locking methods; if you do the order they're declared
# in is important to avoid deadlocks if other MTAs/MUAs are using multiple
# locking methods as well. Some operating systems don't allow using some of
# them simultaneously.
#mbox_read_locks = fcntl
#mbox_write_locks = fcntl

# Maximum time in seconds to wait for lock (all of them) before aborting.
#mbox_lock_timeout = 300

# If dotlock exists but the mailbox isn't modified in any way, override the
# lock file after this many seconds.
#mbox_dotlock_change_timeout = 120

# When mbox changes unexpectedly we have to fully read it to find out what
# changed. If the mbox is large this can take a long time. Since the change
# is usually just a newly appended mail, it'd be faster to simply read the
# new mails. If this setting is enabled, Dovecot does this but still safely
# fallbacks to re-reading the whole mbox file whenever something in mbox
isn't
# how it's expected to be. The only real downside to this setting is that if
# some other MUA changes message flags, Dovecot doesn't notice it
immediately.
# Note that a full sync is done with SELECT, EXAMINE, EXPUNGE and CHECK
# commands.
#mbox_dirty_syncs = yes

# Like mbox_dirty_syncs, but don't do full syncs even with SELECT, EXAMINE,
# EXPUNGE or CHECK commands. If this is set, mbox_dirty_syncs is ignored.
#mbox_very_dirty_syncs = no

# Delay writing mbox headers until doing a full write sync (EXPUNGE and
CHECK
# commands and when closing the mailbox). This is especially useful for POP3
# where clients often delete all mails. The downside is that our changes
# aren't immediately visible to other MUAs.
#mbox_lazy_writes = yes

# If mbox size is smaller than this (in kilobytes), don't write index files.
# If an index file already exists it's still read, just not updated.
#mbox_min_index_size = 0

##
## dbox-specific settings
##

# Maximum dbox file size in kilobytes until it's rotated.
#dbox_rotate_size = 2048

# Minimum dbox file size in kilobytes before it's rotated
# (overrides dbox_rotate_days)
#dbox_rotate_min_size = 16

# Maximum dbox file age in days until it's rotated. Day always begins from
# midnight, so 1 = today, 2 = yesterday, etc. 0 = check disabled.

## IMAP specific settings
##

  # Workarounds for various client bugs:
  #   delay-newmail:
  #     Send EXISTS/RECENT new mail notifications only when replying to NOOP
  #     and CHECK commands. Some clients ignore them otherwise, for
example OSX
  #     Mail (<v2.1). Outlook Express breaks more badly though, without
this it
  #     may show user "Message no longer in server" errors. Note that
OE6 still
  #     breaks even with this workaround if synchronization is set to
  #     "Headers Only".
  #   outlook-idle:
  #     Outlook and Outlook Express never abort IDLE command, so if no mail
  #     arrives in half a hour, Dovecot closes the connection. This is still
  #     fine, except Outlook doesn't connect back so you don't see if
new mail
  #     arrives.
  #   netscape-eoh:
  #     Netscape 4.x breaks if message headers don't end with the empty
"end of
  #     headers" line. Normally all messages have this, but setting this
  #     workaround makes sure that Netscape never breaks by adding the
line if
  #     it doesn't exist. This is done only for FETCH BODY[HEADER.FIELDS..]
  #     commands. Note that RFC says this shouldn't be done.
  #   tb-extra-mailbox-sep:

# referenced using URIs in format "proxy:<name>".

## Plugin settings
##

plugin {
  # Here you can give some extra environment variables to mail processes.
  # This is mostly meant for passing parameters to plugins. %variable
  # expansion is done for all values.

  # Quota plugin. Multiple backends are supported:
  #   dirsize: Find and sum all the files found from mail directory.
  #            Extremely SLOW with Maildir. It'll eat your CPU and disk I/O.
  #   dict: Keep quota stored in dictionary (eg. SQL)
  #   maildir: Maildir++ quota
  #   fs: Read-only support for filesystem quota
  #quota = maildir

  # 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.
  #acl = vfile:/etc/dovecot-acls

  # 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

  # 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

  # 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/
