- # Global Postfix configuration file. This file lists only a subset
- # of all 250+ parameters. See the sample-xxx.cf files for a full list.
- #
- # The general format is lines with parameter = value pairs. Lines
- # that begin with whitespace continue the previous line. A value can
- # contain references to other $names or ${name}s.
- #
- # NOTE - 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.
- #

- # daemon programs (i.e. programs listed in the master.cf file). This
- # directory must be owned by root.
- #
- daemon_directory = /usr/local/intranet/usr/libexec/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

- # 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 = mail.intranet.org
- #myhostname = virtual.domain.tld

- # The default is to use $myhostname minus the first component.
- # $mydomain is used as a default value for many other configuration
- # parameters.
- #
- mydomain = intranet.org
-
- # 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. That includes
- # Sendmail-style virtual domains hosted on this machine.
- #
- # Do not include Postfix-style virtual domains - those domains are
- # specified elsewhere (see sample-virtual.cf, and sample-transport.cf).
- #
- # The default is $myhostname + localhost.$mydomain. On a mail domain
- # gateway, you should also include $mydomain. Do not specify the
- # names of domains that this machine is backup MX host for. Specify
- # those names via the relay_domains or permit_mx_backup settings for
- # the SMTP server (see sample-smtpd.cf).
- #
- # 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. Continue long lines by starting the

-
- # 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 file sample-smtpd.cf.
- #
- # 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).

- # The relay_domains parameter restricts what clients this mail system
- # will relay mail from, or what destinations this system will relay
- # mail to. See the smtpd_recipient_restrictions restriction in the
- # file sample-smtpd.cf for detailed information.
- #
- # By default, Postfix relays mail
- # - from "trusted" clients whose IP address matches $mynetworks,
- # - from "trusted" clients matching $relay_domains or subdomains thereof,
- # - 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 $mydestination
- # - destinations that match $virtual_maps.
- # 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 in the file sample-smtpd.cf.

- # 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.

-
- # REJECTING UNKNOWN LOCAL USERS
- #
- # The local_recipient_maps parameter specifies optional lookup tables
- # with all names (not addresses) of users that are local with respect
- # to $mydestination and $inet_interfaces. If this parameter is
- # defined, then the SMTP server will reject mail for unknown local
- # users.
- #
- # If you use the default Postfix local delivery agent for local
- # delivery, uncomment the definition below.

- #local_recipient_maps = $alias_maps unix:passwd.byname
-
- # 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 50 SMTP server process
- # limit, this limits the mail inflow to 50 messages a second more
- # than the number of messages delivered per second.

- # TRANSPORT MAP
- #
- # Insert text from sample-transport.cf if you need explicit routing.
-
- # 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 = 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

- # 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.

-
- # 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/

- # 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.

- # JUNK MAIL CONTROLS
- #
- # The controls listed here are only a very small subset. See the file

- # 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

- # 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".
- #
- # By default, Postfix maintains deferred mail logfile information
- # only for destinations that Postfix is willing to relay to (as
- # specified in the relay_domains parameter). For other destinations,
- # Postfix attempts to deliver ALL queued mail after receiving the
- # SMTP "ETRN domain.tld" command, or after execution of "sendmail
- # -qRdomain.tld". This can be slow when a lot of mail is queued.

- # 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.
