Mail Server dengan Postfix+Dovecot+Squirrelmail ala wahyu deb4

cara setting mail dengan 3 bumbu saja, (postfix+dovecot+squirrelmail). oke kita langsung saja ke TKP.

1. Install postfix (apt-get install postfix)
seperti biasa sampean harus menghilangkan exim4 di menu:

#aptitude

enter

ni langsung saya beri setingan aja ya, yang sudah ndak default lagi:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific:  Specifying a file name will cause the first # line of that file to be used as the name.  The Debian default # is /etc/mailname. #myorigin = /etc/mailname smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h readme_directory = no # TLS parameters #smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem #smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key #smtpd_use_tls=yes #smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache #smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/lib/postfix mail_owner = postfix mail_spool_directory = /var/spool/mail default_privs = nobody myhostname = server1 alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = lks1.sch.id, server1, localhost.localdomain, localhost #relayhost = server1.lks1.sch.id mynetworks = 127.0.0.0/8 192.168.1.0/29 #mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all mydomain = lks1.sch.id #home_mailbox = Maildir/ default_transport = error relay_transport = error #virtual_maps = hash:/etc/postfix/virtual #transport_maps = hash:/etc/postfix/transport

2. install dovecotnya ini (apt-get install dovecot-imapd dovecot-common dovecot-pop3d)
nd: debian 4 dovecot-pop3d ada di dvd ke-2

ini filenya, monggo copas aja.
## Dovecot configuration file

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

# '#' 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. Exception to this are paths, they're just examples with
# the real defaults being based on configure options. The paths listed here
# are for configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
# --with-ssldir=/etc/ssl

# 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 =

# 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 = *

# 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
##

# Use this logfile instead of syslog(). /dev/stderr can be used if you want to
# use stderr for logging (ONLY /dev/stderr - otherwise it is closed).
#log_path =

# For informational messages, use this logfile instead of the default
#info_log_path =

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

# 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.
#ssl_cert_file = /etc/ssl/certs/dovecot.pem
#ssl_key_file = /etc/ssl/private/dovecot.pem

# If key file is password protected, give the password here. Alternatively
# give it when starting dovecot with -p parameter.
#ssl_key_password =

# 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.
#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_parameters_regenerate = 168

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

# Show protocol level SSL errors.
#verbose_ssl = no

##
## Login processes
##

# 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.
# http://wiki.dovecot.org/Rootless
#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.
# http://wiki.dovecot.org/UserIds
#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@domain, same as %u if there's no domain
#   %d - domain part in user@domain, empty if there's no domain
#   %h - home directory
#
# See /usr/share/doc/dovecot-common/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
#
# http://wiki.dovecot.org/MailLocation
#
#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:
#
# 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.
# The dovecot processes get these groups' privileges in addition to the dovecot
# ones; the list of groups must be separated by spaces.
#mail_extra_groups =
mail_extra_groups = mail

# 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
# /usr/share/doc/dovecot-common/variables.txt for list of possible
# variables you can use.
#mail_log_prefix = "%Us(%u): "

# Use mmap() instead of read() to read mail files. read() seems to be a bit
# faster with my Linux/x86 and it's better with NFS, so that's the default.
# Note that OpenBSD 3.3 and older don't work right with mail_read_mmaped = yes.
#mail_read_mmaped = no

# 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

# 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

# Default umask to use for mail files and directories.
#umask = 0077

# ':' 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. See
# /usr/share/doc/dovecot-common/configuration.txt for more information.
#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.
#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 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

# Copy mail to another folders using hard links. This is much faster than
# actually copying the file. This is problematic only if something modifies
# the mail in one folder but doesn't want it modified in the others. I don't
# know any MUA which would modify mail files directly. IMAP protocol also
# requires that the mails don't change, so it would be problematic in any case.
# If you care about performance, enable it.
#maildir_copy_with_hardlinks = no

##
## mbox-specific settings
##

# Which locking methods to use for locking mbox. There are four available:
#  dotlock: Create .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 = dotlock 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.
#dbox_rotate_days = 0

##
## IMAP specific settings
##

protocol imap {
# Login executable location.
#login_executable = /usr/lib/dovecot/imap-login

# IMAP executable location. Changing this allows you to execute other
# binaries before the imap process is executed.
#
# This would write rawlogs into ~/dovecot.rawlog/ directory:
#   mail_executable = /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap
#
# This would attach gdb into the imap process and write backtraces into
# /tmp/gdbhelper.* files:
#   mail_executable = /usr/libexec/dovecot/gdbhelper /usr/libexec/dovecot/imap
#
#mail_executable = /usr/lib/dovecot/imap

# Maximum IMAP command line length in bytes. Some clients generate very long

# "Too long argument" or "IMAP command line too large" errors often.
#imap_max_line_length = 65536

# Support for dynamically loadable plugins. mail_plugins is a space separated
# list of plugins to load.
#mail_plugins =
#mail_plugin_dir = /usr/lib/dovecot/modules/imap

# Send IMAP capabilities in greeting message. This makes it unnecessary for

# Many clients however don't understand it and ask the CAPABILITY anyway.
#login_greeting_capability = no

# Override the IMAP CAPABILITY response.
#imap_capability =

# 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. 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:
#     With mbox storage a mailbox can contain either mails or submailboxes,
#     but not both. Thunderbird separates these two by forcing server to
#     accept '/' suffix in mailbox names in subscriptions list.
# The list is space-separated.

## POP3 specific settings
##

# how this could be changed.

#pop3_no_flag_updates = no

# Support LAST command which exists in old POP3 specs, but has been removed
# from new ones. Some clients still wish to use this though. Enabling this
# makes RSET command clear all \Seen flags from messages.

#pop3_reuse_xuidl = no

# Keep the mailbox locked for the entire POP3 session.
#pop3_lock_session = no

# POP3 UIDL format to use. You can use following variables:
#
#  %v - Mailbox UIDVALIDITY
#  %u - Mail UID
#  %m - MD5 sum of the mailbox headers in hex (mbox only)
#  %f - filename (maildir only)
#
# If you want UIDL compatibility with other POP3 servers, use:
#  UW's ipop3d         : %08Xv%08Xu
#  Courier version 0   : %f
#  Courier version 1   : %u
#  Courier version 2   : %v-%u
#  Cyrus (<= 2.1.3)    : %u
#  Cyrus (>= 2.1.4)    : %v.%u
#  Older Dovecots      : %v.%u
#  tpop3d              : %Mf
#
# Note that Outlook 2003 seems to have problems with %v.%u format which was
# Dovecot's default, so if you're building a new server it would be a good
# idea to change this. %08Xu%08Xv should be pretty fail-safe.
#
# NOTE: Nowadays this is required to be set explicitly, since the old
# default was bad but it couldn't be changed without breaking existing
# installations. %08Xu%08Xv will be the new default, so use it for new
# installations.

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

# allow both system users (/etc/passwd) and virtual users to login without
# duplicating the system users into virtual database.
#
# http://wiki.dovecot.org/PasswordDatabase
#
# 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.
#
# http://wiki.dovecot.org/MasterPassword

# 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
# checked first. Here's an example:

#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.
# REMEMBER: You'll need /etc/pam.d/dovecot file created for PAM
# authentication to actually work.
# http://wiki.dovecot.org/PasswordDatabase/PAM
passdb pam {
#  [session=yes] [setcred=yes] [cache_key=] []
#
# session=yes makes Dovecot open and immediately close PAM session. Some
# 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.
#
# 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
# /usr/share/doc/dovecot-common/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.
#
# If service name is "*", it means the authenticating service name
# is used, eg. pop3 or imap (/etc/pam.d/pop3, /etc/pam.d/imap).
#
# Some examples:
#   args = session=yes *
#   args = cache_key=%u dovecot
#args = dovecot

# It's possible to export the authentication interface to other programs:
#socket listen {
#master {
# Master socket is typically used to give Dovecot's local delivery
# agent access to userdb so it can find mailbox locations. It can
# however also be used to disturb regular user authentications.
# WARNING: Giving untrusted users access to master socket may be a
# security risk, don't give too wide permissions to it!
#path = /var/run/dovecot/auth-master
#mode = 0600
# Default user/group is the one who started dovecot-auth (root)
#user =
#group =
#}
#client {
# The client socket is generally safe to export to everyone. Typical use
# is to export it to your SMTP server so it can do SMTP AUTH lookups
# using it.
#path = /var/run/dovecot/auth-client
#mode = 0660
#}
#}

## dovecot-lda specific settings
##
# socket listen {
#   master {
#     path = /var/run/dovecot/auth-master
#     mode = 0600
#     user = mail # User running Dovecot LDA
#     #group = mail # Or alternatively mode 0660 + LDA user in this group
#   }
# }

}

# If you wish to use another authentication server than dovecot-auth, you can
# use connect sockets. They assumed to be already running, Dovecot's master
# process only tries to connect to them. They don't need any other settings
# than the path for the master socket, as the configuration is done elsewhere.
# Note that the client sockets must exist in the login_dir.
#auth external {
#  socket connect {
#    master {
#      path = /var/run/dovecot/auth-master
#    }
#  }

## Dictionary server settings
##

# Dictionary can be used by some plugins to store key=value lists.
# Currently this is only used by dict quota backend. The dictionary can be
# used either directly or though a dictionary server. The following dict block
# maps dictionary names to URIs when the server is used. These can then be
# referenced using URIs in format "proxy:".

dict {
#quota = mysql:/etc/dovecot-dict-quota.conf
}

##
## 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
#   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).
#convert_mail = mbox:%h/mail

# 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:
# Mails are first deleted in lowest -> highest priority number order
#trash = /etc/dovecot-trash.conf
}

intinya hanya edit ini saja:
protocols = imap imaps pop3 pop3s
disable_plaintext_auth = no
mail_location = maildir:~/Maildir
login_executable = /usr/lib/dovecot/pop3-login
mail_executable = /usr/lib/dovecot/pop3

restarting paket:
#/etc/init.d/postfix restart
#/etc/init.d/dovecot restart kemudian start

edit sedikit pada /etc/inetd.conf

pop3 stream tcp nowait root /usr/bin/tcpd ipop3d

3. kemudian installasi squirrelmail (apt-get install squirrelmail)
nah agar squirrelmail di baca di web browser maka anda harus menginstall apache2 (apt-get install apache2)

edit sedikit pada /etc/apache2/apache2.conf
pada bagian bawah ketikkan kode ini:

Include /etc/squirrelmail/apache.conf

cara create user dengan perintah:

adduser admin password terserah kemudian save y

cara memanggil di browser:

domain_anda.terserah/squirrelmail atau ip_domain/squirrelmail

Semoga apa yg menjadi tutorial ini dpt bermanfaat.
