 +====== Allgemein ======
 +
 +Die Hauptkonfigurationsdatei von Postfix ist **/​usr/​local/​etc/​postfix/​main.cf**
 +
 +Anbei eine **main.cf** die angepasst wurde um Mails über einen Relay (in diesem Fall 1und1) zu versenden.
 +
 +Damit Postfix SASL und TSL unterstützt um Mails über den Relay zu versenden muss Postfix mit folgenden Optionen übersetzt worden sein.

 +# Global Postfix configuration file. This file lists only a subset
 +# of all parameters. For the syntax, and for a complete parameter
 +# list, see the postconf(5) manual page (command: "man 5 postconf"​).
 +#
 +# For common configuration examples, see BASIC_CONFIGURATION_README
 +# and STANDARD_CONFIGURATION_README. To find these documents, use
 +# the command "​postconf html_directory readme_directory",​ or go to
 +# http://​www.postfix.org/​.
 +#
 +# For best results, change no more than 2-3 parameters at a time,
 +# and test if Postfix still works after every change.
 +
 +# SOFT BOUNCE
 +#
 +# The soft_bounce parameter provides a limited safety net for
 +# testing. ​ When soft_bounce is enabled, mail will remain queued that
 +# would otherwise bounce. This parameter disables locally-generated
 +# bounces, and prevents the SMTP server from rejecting mail permanently
 +# (by changing 5xx replies into 4xx replies). However, soft_bounce
 +# is no cure for address rewriting mistakes or mail routing mistakes.
 +#
 +#​soft_bounce = no
 +
 +# LOCAL PATHNAME INFORMATION
 +#
 +# The queue_directory specifies the location of the Postfix queue.
 +# This is also the root directory of Postfix daemons that run chrooted.
 +# See the files in examples/​chroot-setup for setting up Postfix chroot
 +# environments on different UNIX systems.
 +#
 +queue_directory = /​var/​spool/​postfix
 +
 +# The command_directory parameter specifies the location of all
 +# postXXX commands.
 +#
 +command_directory = /​usr/​local/​sbin
 +
 +# The daemon_directory parameter specifies the location of all Postfix
 +# daemon programs (i.e. programs listed in the master.cf file). This
 +# directory must be owned by root.
 +#
 +daemon_directory = /​usr/​local/​libexec/​postfix
 +
 +# The data_directory parameter specifies the location of Postfix-writable
 +# data files (caches, random numbers). This directory must be owned
 +# by the mail_owner account (see below).
 +#
 +data_directory = /​var/​db/​postfix
 +
 +# QUEUE AND PROCESS OWNERSHIP
 +#
 +# The mail_owner parameter specifies the owner of the Postfix queue
 +# and of most Postfix daemon processes. ​ Specify the name of a user
 +# account THAT DOES NOT SHARE ITS USER OR GROUP ID WITH OTHER ACCOUNTS
 +# AND THAT OWNS NO OTHER FILES OR PROCESSES ON THE SYSTEM. ​ In
 +# particular, don't specify nobody or daemon. PLEASE USE A DEDICATED
 +# USER.
 +#
 +mail_owner = postfix
 +
 +# The default_privs parameter specifies the default rights used by
 +# the local delivery agent for delivery to external file or command.
 +# These rights are used in the absence of a recipient user context.
 +# DO NOT SPECIFY A PRIVILEGED USER OR THE POSTFIX OWNER.
 +#
 +#​default_privs = nobody
 +
 +# INTERNET HOST AND DOMAIN NAMES
 +
 +# The myhostname parameter specifies the internet hostname of this
 +# mail system. The default is to use the fully-qualified domain name
 +# from gethostname(). $myhostname is used as a default value for many
 +# other configuration parameters.
 +#
 +#myhostname = host.domain.tld
 +#myhostname = virtual.domain.tld
 +
 +# The mydomain parameter specifies the local internet domain name.
 +# The default is to use $myhostname minus the first component.
 +# $mydomain is used as a default value for many other configuration
 +# parameters.
 +#
 +#mydomain = domain.tld
 +
 +# SENDING MAIL
 +
 +# The myorigin parameter specifies the domain that locally-posted
 +# mail appears to come from. The default is to append $myhostname,​
 +# which is fine for small sites. ​ If you run a domain with multiple
 +# machines, you should (1) change this to $mydomain and (2) set up
 +# a domain-wide alias database that aliases each user to
 +# user@that.users.mailhost.
 +#
 +# For the sake of consistency between sender and recipient addresses,
 +# myorigin also specifies the default domain name that is appended
 +# to recipient addresses that have no @domain part.
 +#
 +#myorigin = $myhostname
 +#myorigin = $mydomain
 +
 +# RECEIVING MAIL
 +
 +# The inet_interfaces parameter specifies the network interface
 +# addresses that this mail system receives mail on.  By default,
 +# the software claims all active interfaces on the machine. The
 +# parameter also controls delivery of mail to user@[ip.address].
 +#
 +# See also the proxy_interfaces parameter, for network addresses that
 +# are forwarded to us via a proxy or network address translator.
 +#
 +# Note: you need to stop/start Postfix when this parameter changes.
 +#
 +#​inet_interfaces = all
 +#​inet_interfaces = $myhostname
 +#​inet_interfaces = $myhostname,​ localhost
 +
 +# The proxy_interfaces parameter specifies the network interface
 +# addresses that this mail system receives mail on by way of a
 +# proxy or network address translation unit. This setting extends
 +# the address list specified with the inet_interfaces parameter.
 +#
 +# You must specify your proxy/NAT addresses when your system is a
 +# backup MX host for other domains, otherwise mail delivery loops
 +# will happen when the primary MX host is down.
 +#
 +#​proxy_interfaces =
 +#​proxy_interfaces = 1.2.3.4
 +
 +# The mydestination parameter specifies the list of domains that this
 +# machine considers itself the final destination for.
 +#
 +# These domains are routed to the delivery agent specified with the
 +# 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. ​ On a mail domain
 +# gateway, you should also include $mydomain.
 +#
 +# Do not specify the names of virtual domains - those domains are
 +# specified elsewhere (see VIRTUAL_README).
 +#
 +# Do not specify the names of domains that this machine is backup MX
 +# host for. Specify those names via the relay_domains settings for
 +# the SMTP server, or use permit_mx_backup if you are lazy (see
 +# STANDARD_CONFIGURATION_README).
 +#
 +# The local machine is always the final destination for mail addressed
 +# 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
 +# a name matches a lookup key (the right-hand side is ignored).
 +# Continue long lines by starting the next line with whitespace.
 +#
 +# See also below, section "​REJECTING MAIL FOR UNKNOWN LOCAL USERS"​.
 +#
 +#​mydestination = $myhostname,​ localhost.$mydomain,​ localhost
 +#​mydestination = $myhostname,​ localhost.$mydomain,​ localhost, $mydomain
 +#​mydestination = $myhostname,​ localhost.$mydomain,​ localhost, $mydomain,
 +#​\tmail.$mydomain,​ www.$mydomain,​ ftp.$mydomain
 +
 +# 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.
 +
 +#​local_recipient_maps = unix:​passwd.byname $alias_maps
 +#​local_recipient_maps = proxy:​unix:​passwd.byname $alias_maps
 +#​local_recipient_maps =
 +
 +# The unknown_local_recipient_reject_code specifies the SMTP server
 +# 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
 +# with 450 (try again later) until you are certain that your
 +# local_recipient_maps settings are OK.
 +#
 +unknown_local_recipient_reject_code = 550
 +
 +# TRUST AND RELAY CONTROL
 +
 +# The mynetworks parameter specifies the list of "​trusted"​ SMTP
 +# 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 does 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 = 168.100.189.0/​28,​ 127.0.0.0/8
 +#mynetworks = $config_directory/​mynetworks
 +#mynetworks = hash:​$config_directory/​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.

 +
 +# REJECTING UNKNOWN RELAY USERS
 +#
 +# The relay_recipient_maps parameter specifies optional lookup tables
 +# with all addresses in the domains that match $relay_domains.
 +#
 +# If this parameter is defined, then the SMTP server will reject
 +# mail for unknown relay users. This feature is off by default.
 +#
 +# The right-hand side of the lookup tables is conveniently ignored.
 +# In the left-hand side, specify an @domain.tld wild-card, or specify
 +# a user@domain.tld address.
 +
 +#​relay_recipient_maps = hash:​$config_directory/​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
 +# accepting a new message, when the message arrival rate exceeds the
 +# message delivery rate. With the default 100 SMTP server process
 +# limit, this limits the mail inflow to 100 messages a second more
 +# than the number of messages delivered per second.
 +
 +# Specify 0 to disable the feature. Valid delays are 0..10.
 +
 +#​in_flow_delay = 1s
 +
 +# ADDRESS REWRITING
 +#
 +# The ADDRESS_REWRITING_README document gives information about
 +# address masquerading or other forms of address rewriting including
 +# username->​Firstname.Lastname mapping.
 +
 +# ADDRESS REDIRECTION (VIRTUAL DOMAIN)
 +#
 +# The VIRTUAL_README document gives information about the many forms
 +# of domain hosting that Postfix supports.
 +
 +# "USER HAS MOVED" BOUNCE MESSAGES
 +#
 +# See the discussion in the ADDRESS_REWRITING_README document.
 +
 +# TRANSPORT MAP
 +#
 +# See the discussion in the ADDRESS_REWRITING_README document.
 +
 +# 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 = 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"​.
 +#
 +#​mailbox_transport = lmtp:​unix:/​file/​name
 +#​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
 +# file, then you must update the "​local_recipient_maps"​ setting in

 +#
 +#​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"​.

 +  ​
 +# 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:​$config_directory/​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
