-# To avoid breaking things, Postfix will use backwards-compatible
-# default settings and log where it uses those old backwards-compatible

-# local_transport parameter setting. By default, that is the UNIX
-# compatible delivery agent that lookups all recipients in /etc/passwd
-# and /etc/aliases or their equivalent.
-#
-# The default is $myhostname + localhost.$mydomain + localhost.  On

-# to user@[the.net.work.address] of an interface that the mail system
-# receives mail on (see the inet_interfaces parameter).
-#
-# Specify a list of host or domain names, /file/name or type:table
-# patterns, separated by commas and/or whitespace. A /file/name
-# pattern is replaced by its contents; a type:table is matched when

-# REJECTING MAIL FOR UNKNOWN LOCAL USERS
-#
-# The local_recipient_maps parameter specifies optional lookup tables
-# with all names or addresses of users that are local with respect
-# to $mydestination, $inet_interfaces or $proxy_interfaces.
-#
-# If this parameter is defined, then the SMTP server will reject
-# mail for unknown local users. This parameter is defined by default.
-#
-# To turn off local recipient checking in the SMTP server, specify
-# local_recipient_maps = (i.e. empty).
-#
-# The default setting assumes that you use the default Postfix local
-# delivery agent for local delivery. You need to update the
-# local_recipient_maps setting if:
-#
-# - You define $mydestination domain recipients in files other than
-#   /etc/passwd, /etc/aliases, or the $virtual_alias_maps files.
-#   For example, you define $mydestination domain recipients in
-#   the $virtual_mailbox_maps files.
-#
-# - You redefine the local delivery agent in master.cf.
-#
-# - You redefine the "local_transport" setting in main.cf.
-#
-# - You use the "luser_relay", "mailbox_transport", or "fallback_transport"
-#   feature of the Postfix local delivery agent (see local(8)).
-#
-# Details are described in the LOCAL_RECIPIENT_README file.
-#
-# Beware: if the Postfix SMTP server runs chrooted, you probably have
-# to access the passwd file via the proxymap service, in order to
-# overcome chroot restrictions. The alternative, having a copy of
-# the system passwd file in the chroot jail is just not practical.
-#
-# The right-hand side of the lookup tables is conveniently ignored.
-# In the left-hand side, specify a bare username, an @domain.tld
-# wild-card, or specify a user@domain.tld address.

-# response code when a recipient domain matches $mydestination or
-# ${proxy,inet}_interfaces, while $local_recipient_maps is non-empty
-# and the recipient address or address local-part is not found.
-#
-# The default setting is 550 (reject mail) but it is safer to start

-# TRUST AND RELAY CONTROL
-

-# clients that have more privileges than "strangers".
-#
-# In particular, "trusted" SMTP clients are allowed to relay mail
-# through Postfix.  See the smtpd_recipient_restrictions parameter
-# in postconf(5).
-#
-# You can specify the list of "trusted" network addresses by hand
-# or you can let Postfix do it for you (which is the default).
-#
-# By default (mynetworks_style = subnet), Postfix "trusts" SMTP
-# clients in the same IP subnetworks as the local machine.
-# On Linux, this works correctly only with interfaces specified
-# with the "ifconfig" command.
-#
-# Specify "mynetworks_style = class" when Postfix should "trust" SMTP
-# clients in the same IP class A/B/C networks as the local machine.
-# Don't do this with a dialup site - it would cause Postfix to "trust"
-# your entire provider's network.  Instead, specify an explicit
-# mynetworks list by hand, as described below.
-#
-# Specify "mynetworks_style = host" when Postfix should "trust"
-# only the local machine.
-#
-#mynetworks_style = class
-#mynetworks_style = subnet
-#mynetworks_style = host
-
-# Alternatively, you can specify the mynetworks list by hand, in
-# which case Postfix ignores the mynetworks_style setting.
-#
-# Specify an explicit list of network/netmask patterns, where the
-# mask specifies the number of bits in the network part of a host
-# address.
-#
-# You can also specify the absolute pathname of a pattern file instead
-# of listing the patterns here. Specify type:table for table-based lookups
-# (the value on the table right-hand side is not used).
-#
-mynetworks = mailman-core,mailman-web
-#mynetworks = $config_directory/mynetworks
-#mynetworks = hash:/etc/postfix/network_table
-
-# The relay_domains parameter restricts what destinations this system will
-# relay mail to.  See the smtpd_recipient_restrictions description in
-# postconf(5) for detailed information.
-#
-# By default, Postfix relays mail
-# - from "trusted" clients (IP address matches $mynetworks) to any destination,
-# - from "untrusted" clients to destinations that match $relay_domains or
-#   subdomains thereof, except addresses with sender-specified routing.
-# The default relay_domains value is $mydestination.
-#
-# In addition to the above, the Postfix SMTP server by default accepts mail
-# that Postfix is final destination for:
-# - destinations that match $inet_interfaces or $proxy_interfaces,
-# - destinations that match $mydestination
-# - destinations that match $virtual_alias_domains,
-# - destinations that match $virtual_mailbox_domains.
-# These destinations do not need to be listed in $relay_domains.
-#
-# Specify a list of hosts or domains, /file/name patterns or type:name
-# lookup tables, separated by commas and/or whitespace.  Continue
-# long lines by starting the next line with whitespace. A file name
-# is replaced by its contents; a type:name table is matched when a
-# (parent) domain appears as lookup key.
-#
-# NOTE: Postfix will not automatically forward mail for domains that
-# list this system as their primary or backup MX host. See the
-# permit_mx_backup restriction description in postconf(5).
-#
-#relay_domains = $mydestination
-
-# INTERNET OR INTRANET
-
-# The relayhost parameter specifies the default host to send mail to
-# when no entry is matched in the optional transport(5) table. When
-# no relayhost is given, mail is routed directly to the destination.
-#
-# On an intranet, specify the organizational domain name. If your
-# internal DNS uses no MX records, specify the name of the intranet
-# gateway host instead.
-#
-# In the case of SMTP, specify a domain, host, host:port, [host]:port,
-# [address] or [address]:port; the form [host] turns off MX lookups.
-#
-# If you're connected via UUCP, see also the default_transport parameter.

-#relayhost = [gateway.my.domain]
-#relayhost = [mailserver.isp.tld]
-#relayhost = uucphost

-# REJECTING UNKNOWN RELAY USERS
-#
-# The relay_recipient_maps parameter specifies optional lookup tables
-# with all addresses in the domains that match $relay_domains.
-#
-# If this parameter is defined, then the SMTP server will reject

-#
-#relay_recipient_maps = hash:/etc/postfix/relay_recipients
-
-# INPUT RATE CONTROL
-#
-# The in_flow_delay configuration parameter implements mail input
-# flow control. This feature is turned on by default, although it
-# still needs further development (it's disabled on SCO UNIX due
-# to an SCO bug).
-#
-# A Postfix process will pause for $in_flow_delay seconds before

-# ALIAS DATABASE
-#
-# The alias_maps parameter specifies the list of alias databases used
-# by the local delivery agent. The default list is system dependent.
-#
-# On systems with NIS, the default is to search the local alias
-# database, then the NIS alias database. See aliases(5) for syntax
-# details.
-#
-# If you change the alias database, run "postalias /etc/aliases" (or
-# wherever your system stores the mail alias file), or simply run
-# "newaliases" to build the necessary DBM or DB file.
-#
-# It will take a minute or so before changes become visible.  Use
-# "postfix reload" to eliminate the delay.
-#
-#alias_maps = dbm:/etc/aliases
-#alias_maps = hash:/etc/aliases
-#alias_maps = hash:/etc/aliases, nis:mail.aliases
-#alias_maps = netinfo:/aliases
-
-# The alias_database parameter specifies the alias database(s) that
-# are built with "newaliases" or "sendmail -bi".  This is a separate
-# configuration parameter, because alias_maps (see above) may specify
-# tables that are not necessarily all under control by Postfix.
-#
-#alias_database = dbm:/etc/aliases
-#alias_database = dbm:/etc/mail/aliases
-#alias_database = hash:/etc/aliases
-#alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases
-
-# ADDRESS EXTENSIONS (e.g., user+foo)
-#
-# The recipient_delimiter parameter specifies the separator between
-# user names and address extensions (user+foo). See canonical(5),
-# local(8), relocated(5) and virtual(5) for the effects this has on
-# aliases, canonical, virtual, relocated and .forward file lookups.
-# Basically, the software tries user+foo and .forward+foo before
-# trying user and .forward.
-#
-#recipient_delimiter = +
-
-# DELIVERY TO MAILBOX
-#
-# The home_mailbox parameter specifies the optional pathname of a
-# mailbox file relative to a user's home directory. The default
-# mailbox file is /var/spool/mail/user or /var/mail/user.  Specify
-# "Maildir/" for qmail-style delivery (the / is required).
-#
-#home_mailbox = Mailbox
-#home_mailbox = Maildir/
-
-# The mail_spool_directory parameter specifies the directory where
-# UNIX-style mailboxes are kept. The default setting depends on the
-# system type.
-#
-#mail_spool_directory = /var/mail
-#mail_spool_directory = /var/spool/mail
-
-# The mailbox_command parameter specifies the optional external
-# command to use instead of mailbox delivery. The command is run as
-# the recipient with proper HOME, SHELL and LOGNAME environment settings.
-# Exception:  delivery for root is done as $default_user.
-#
-# Other environment variables of interest: USER (recipient username),
-# EXTENSION (address extension), DOMAIN (domain part of address),
-# and LOCAL (the address localpart).
-#
-# Unlike other Postfix configuration parameters, the mailbox_command
-# parameter is not subjected to $parameter substitutions. This is to
-# make it easier to specify shell syntax (see example below).
-#
-# Avoid shell meta characters because they will force Postfix to run
-# an expensive shell process. Procmail alone is expensive enough.
-#
-# IF YOU USE THIS TO DELIVER MAIL SYSTEM-WIDE, YOU MUST SET UP AN
-# ALIAS THAT FORWARDS MAIL FOR ROOT TO A REAL USER.
-#
-#mailbox_command = /some/where/procmail
-#mailbox_command = /some/where/procmail -a "$EXTENSION"
-
-# The mailbox_transport specifies the optional transport in master.cf
-# to use after processing aliases and .forward files. This parameter
-# has precedence over the mailbox_command, fallback_transport and
-# luser_relay parameters.
-#
-# Specify a string of the form transport:nexthop, where transport is
-# the name of a mail delivery transport defined in master.cf.  The
-# :nexthop part is optional. For more details see the sample transport
-# configuration file.
-#
-# NOTE: if you use this feature for accounts not in the UNIX password
-# file, then you must update the "local_recipient_maps" setting in
-# the main.cf file, otherwise the SMTP server will reject mail for
-# non-UNIX accounts with "User unknown in local recipient table".
-#
-# Cyrus IMAP over LMTP. Specify ``lmtpunix      cmd="lmtpd"
-# listen="/var/imap/socket/lmtp" prefork=0'' in cyrus.conf.
-#mailbox_transport = lmtp:unix:/var/imap/socket/lmtp
-#
-# Cyrus IMAP via command line. Uncomment the "cyrus...pipe" and
-# subsequent line in master.cf.
-#mailbox_transport = cyrus
-
-# The fallback_transport specifies the optional transport in master.cf
-# to use for recipients that are not found in the UNIX passwd database.
-# This parameter has precedence over the luser_relay parameter.
-#
-# Specify a string of the form transport:nexthop, where transport is
-# the name of a mail delivery transport defined in master.cf.  The
-# :nexthop part is optional. For more details see the sample transport
-# configuration file.
-#
-# NOTE: if you use this feature for accounts not in the UNIX password

-#
-#fallback_transport = lmtp:unix:/file/name
-#fallback_transport = cyrus
-#fallback_transport =
-
-# The luser_relay parameter specifies an optional destination address
-# for unknown recipients.  By default, mail for unknown@$mydestination,
-# unknown@[$inet_interfaces] or unknown@[$proxy_interfaces] is returned
-# as undeliverable.
-#
-# The following expansions are done on luser_relay: $user (recipient
-# username), $shell (recipient shell), $home (recipient home directory),
-# $recipient (full recipient address), $extension (recipient address
-# extension), $domain (recipient domain), $local (entire recipient
-# localpart), $recipient_delimiter. Specify ${name?value} or
-# ${name:value} to expand value only when $name does (does not) exist.
-#
-# luser_relay works only for the default Postfix local delivery agent.
-#
-# NOTE: if you use this feature for accounts not in the UNIX password
-# file, then you must specify "local_recipient_maps =" (i.e. empty) in
-# the main.cf file, otherwise the SMTP server will reject mail for
-# non-UNIX accounts with "User unknown in local recipient table".

-#luser_relay = $user@other.host
-#luser_relay = $local@other.host
-#luser_relay = admin+$local
-
-# JUNK MAIL CONTROLS
-#
-# The controls listed here are only a very small subset. The file
-# SMTPD_ACCESS_README provides an overview.
-
-# The header_checks parameter specifies an optional table with patterns
-# that each logical message header is matched against, including
-# headers that span multiple physical lines.
-#
-# By default, these patterns also apply to MIME headers and to the
-# headers of attached messages. With older Postfix versions, MIME and
-# attached message headers were treated as body text.
-#
-# For details, see "man header_checks".
-#
-#header_checks = regexp:/etc/postfix/header_checks
-
-# FAST ETRN SERVICE
-#
-# Postfix maintains per-destination logfiles with information about
-# deferred mail, so that mail can be flushed quickly with the SMTP
-# "ETRN domain.tld" command, or by executing "sendmail -qRdomain.tld".
-# See the ETRN_README document for a detailed description.
-#
-# The fast_flush_domains parameter controls what destinations are
-# eligible for this service. By default, they are all domains that
-# this server is willing to relay mail to.
-#
-#fast_flush_domains = $relay_domains
-
-# SHOW SOFTWARE VERSION OR NOT
-#
-# The smtpd_banner parameter specifies the text that follows the 220
-# code in the SMTP server's greeting banner. Some people like to see
-# the mail version advertised. By default, Postfix shows no version.
-#
-# You MUST specify $myhostname at the start of the text. That is an
-# RFC requirement. Postfix itself does not care.
-#
-#smtpd_banner = $myhostname ESMTP $mail_name
-#smtpd_banner = $myhostname ESMTP $mail_name ($mail_version)
-
-# PARALLEL DELIVERY TO THE SAME DESTINATION
-#
-# How many parallel deliveries to the same user or domain? With local
-# delivery, it does not make sense to do massively parallel delivery
-# to the same user, because mailbox updates must happen sequentially,
-# and expensive pipelines in .forward files can cause disasters when
-# too many are run at the same time. With SMTP deliveries, 10
-# simultaneous connections to the same domain could be sufficient to
-# raise eyebrows.
-#
-# Each message delivery transport has its XXX_destination_concurrency_limit
-# parameter.  The default is $default_destination_concurrency_limit for
-# most delivery transports. For the local delivery agent the default is 2.
-
-#local_destination_concurrency_limit = 2
-#default_destination_concurrency_limit = 20
-
-# DEBUGGING CONTROL

-# The debug_peer_level parameter specifies the increment in verbose
-# logging level when an SMTP client or server host name or address
-# matches a pattern in the debug_peer_list parameter.
-#
-debug_peer_level = 2
-
-# The debug_peer_list parameter specifies an optional list of domain
-# or network patterns, /file/name patterns or type:name tables. When
-# an SMTP client or server host name or address matches a pattern,
-# increase the verbose logging level by the amount specified in the
-# debug_peer_level parameter.
-#
-#debug_peer_list = 127.0.0.1
-#debug_peer_list = some.domain
-
-# The debugger_command specifies the external command that is executed
-# when a Postfix daemon program is run with the -D option.
-#
-# Use "command .. & sleep 5" so that the debugger can attach before
-# the process marches on. If you use an X-based debugger, be sure to
