# Global Postfix configuration file. This file lists only a subset # of all 100+ 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. # queue_directory = /var/spool/postfix # The command_directory parameter specifies the location of all # postXXX commands. The default value is $program_directory. # command_directory = /usr/sbin # The daemon_directory parameter specifies the location of all Postfix # daemon programs (i.e. programs listed in the master.cf file). The # default value is $program_directory. This directory must be owned # by root. # daemon_directory = /usr/lib/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 = gateway.framp.local #myhostname = virtual.domain.name # 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 = framp.local # 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. # #myorigin = $myhostname myorigin = $mydomain #myorigin = framp.de # 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]. # #inet_interfaces = all #inet_interfaces = $myhostname #inet_interfaces = $myhostname, localhost # 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 # next line with whitespace. # #mydestination = $myhostname, localhost.$mydomain #mydestination = $myhostname, localhost.$mydomain, $mydomain #mydestination = $myhostname, localhost.$mydomain, $mydomain, # mail.$mydomain, www.$mydomain, ftp.$mydomain # 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). # mynetworks = 192.168.0.0/24, 127.0.0.0/8 #mynetworks = 168.100.189.0/28, 127.0.0.0/8 #mynetworks = $config_directory/mynetworks #mynetworks = hash:/etc/postfix/network_table # 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 $inet_interfaces, # - 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. # #relay_domains = $mydestination #relay_domains = # 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 = $mydomain #relayhost = gateway.my.domain #relayhost = uucphost #relayhost = [an.ip.add.ress] #relayhost = [post.strato.de] # REJECTING UNKNOWN LOCAL USERS # # The local_recipient_maps parameter specifies optional lookup tables # with all 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. # # Beware: if the Postfix SMTP server runs chrooted, you may have to # copy the passwd (not shadow) database into the jail. This is # system dependent. # #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. # # Specify 0 to disable the feature. Valid delays are 0..10. # #in_flow_delay = 1s # ADDRESS REWRITING # # Insert text from sample-rewrite.cf if you need to do address # masquerading. # # Insert text from sample-canonical.cf if you need to do address # rewriting, or if you need username->Firstname.Lastname mapping. # ADDRESS REDIRECTION (VIRTUAL DOMAIN) # # Insert text from sample-virtual.cf if you need virtual domain support. # "USER HAS MOVED" BOUNCE MESSAGES # # Insert text from sample-relocated.cf if you need "user has moved" # style bounce messages. Alternatively, you can bounce recipients # with an SMTP server access table. See sample-smtpd.cf. # 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 = 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. # #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. # #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 local recipients # is bounced. # # 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. # #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. See the file # sample-smtpd.cf for an elaborate list of anti-UCE controls. # 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. Patterns are matched # in the specified order, and the search stops upon the first match. # When a pattern matches, what happens next depends on the associated # action that is specified in the right-hand side of the table: # # REJECT the entire message is rejected. # REJECT text.... The text is sent to the originator. # IGNORE the header line is silently discarded. # WARN the header is logged (not rejected) with a warning message. # # These patterns do not apply to MIME headers in the message body. # # See also the body_checks example in the sample-filter.cf file. # header_checks = regexp:/etc/postfix/header_checks #mime_header_checks = regexp:/etc/postfix/mime_header_checks #body_checks = regexp:/etc/postfix/body_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.name" command, or by executing "sendmail -qRdomain.name". # # 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.name" command, or after execution of "sendmail # -qRdomain.name". This can be slow when a lot of mail is queued. # # The fast_flush_domains parameter controls what destinations are # eligible for this "fast ETRN/sendmail -qR" service. # #fast_flush_domains = $relay_domains fast_flush_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.

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.
