1# $NetBSD: main.cf,v 1.9 2022/10/08 16:12:43 christos Exp $ 2# 3# Global Postfix configuration file. This file lists only a subset 4# of all parameters. For the syntax, and for a complete parameter 5# list, see the postconf(5) manual page (command: "man 5 postconf"). 6# 7# TIP: use the command "postconf -n" to view main.cf parameter 8# settings, "postconf parametername" to view a specific parameter, 9# and "postconf 'parametername=value'" to set a specific parameter. 10# 11# For common configuration examples, see BASIC_CONFIGURATION_README 12# and STANDARD_CONFIGURATION_README. To find these documents, use 13# the command "postconf html_directory readme_directory", or go to 14# http://www.postfix.org/BASIC_CONFIGURATION_README.html etc. 15# 16# For best results, change no more than 2-3 parameters at a time, 17# and test if Postfix still works after every change. 18 19# COMPATIBILITY 20# 21# The compatibility_level determines what default settings Postfix 22# will use for main.cf and master.cf settings. These defaults will 23# change over time. 24# 25# To avoid breaking things, Postfix will use backwards-compatible 26# default settings and log where it uses those old backwards-compatible 27# default settings, until the system administrator has determined 28# if any backwards-compatible default settings need to be made 29# permanent in main.cf or master.cf. 30# 31# When this review is complete, update the compatibility_level setting 32# below as recommended in the RELEASE_NOTES file. 33# 34# The level below is what should be used with new (not upgrade) installs. 35# 36compatibility_level = 3.7 37 38# On NetBSD we are built without EAI support, so we must disable utf8 39smtputf8_enable=no 40 41# SOFT BOUNCE 42# 43# The soft_bounce parameter provides a limited safety net for 44# testing. When soft_bounce is enabled, mail will remain queued that 45# would otherwise bounce. This parameter disables locally-generated 46# bounces, and prevents the SMTP server from rejecting mail permanently 47# (by changing 5xx replies into 4xx replies). However, soft_bounce 48# is no cure for address rewriting mistakes or mail routing mistakes. 49# 50#soft_bounce = no 51 52# LOCAL PATHNAME INFORMATION 53# 54# The queue_directory specifies the location of the Postfix queue. 55# This is also the root directory of Postfix daemons that run chrooted. 56# See the files in examples/chroot-setup for setting up Postfix chroot 57# environments on different UNIX systems. 58# 59queue_directory = /var/spool/postfix 60 61# The command_directory parameter specifies the location of all 62# postXXX commands. 63# 64command_directory = /usr/sbin 65 66# The daemon_directory parameter specifies the location of all Postfix 67# daemon programs (i.e. programs listed in the master.cf file). This 68# directory must be owned by root. 69# 70daemon_directory = /usr/libexec/postfix 71 72# The data_directory parameter specifies the location of Postfix-writable 73# data files (caches, random numbers). This directory must be owned 74# by the mail_owner account (see below). 75# 76data_directory = /var/db/postfix 77 78# QUEUE AND PROCESS OWNERSHIP 79# 80# The mail_owner parameter specifies the owner of the Postfix queue 81# and of most Postfix daemon processes. Specify the name of a user 82# account THAT DOES NOT SHARE ITS USER OR GROUP ID WITH OTHER ACCOUNTS 83# AND THAT OWNS NO OTHER FILES OR PROCESSES ON THE SYSTEM. In 84# particular, don't specify nobody or daemon. PLEASE USE A DEDICATED 85# USER. 86# 87mail_owner = postfix 88 89# The default_privs parameter specifies the default rights used by 90# the local delivery agent for delivery to external file or command. 91# These rights are used in the absence of a recipient user context. 92# DO NOT SPECIFY A PRIVILEGED USER OR THE POSTFIX OWNER. 93# 94#default_privs = nobody 95 96# INTERNET HOST AND DOMAIN NAMES 97# 98# The myhostname parameter specifies the internet hostname of this 99# mail system. The default is to use the fully-qualified domain name 100# from gethostname(). $myhostname is used as a default value for many 101# other configuration parameters. 102# 103#myhostname = host.domain.tld 104#myhostname = virtual.domain.tld 105 106# The mydomain parameter specifies the local internet domain name. 107# The default is to use $myhostname minus the first component. 108# $mydomain is used as a default value for many other configuration 109# parameters. 110# 111#mydomain = domain.tld 112 113# SENDING MAIL 114# 115# The myorigin parameter specifies the domain that locally-posted 116# mail appears to come from. The default is to append $myhostname, 117# which is fine for small sites. If you run a domain with multiple 118# machines, you should (1) change this to $mydomain and (2) set up 119# a domain-wide alias database that aliases each user to 120# user@that.users.mailhost. 121# 122# For the sake of consistency between sender and recipient addresses, 123# myorigin also specifies the default domain name that is appended 124# to recipient addresses that have no @domain part. 125# 126#myorigin = $myhostname 127#myorigin = $mydomain 128 129# RECEIVING MAIL 130 131# The inet_interfaces parameter specifies the network interface 132# addresses that this mail system receives mail on. By default, 133# the software claims all active interfaces on the machine. The 134# parameter also controls delivery of mail to user@[ip.address]. 135# 136# NOTE: On NetBSD, postfix does not listen on the network by default. 137# To enable inbound mail reception once your configuration is 138# ready, uncomment the smtp service in /etc/postfix/master.cf 139# 140# See also the proxy_interfaces parameter, for network addresses that 141# are forwarded to us via a proxy or network address translator. 142# 143# Note: you need to stop/start Postfix when this parameter changes. 144# 145#inet_interfaces = all 146#inet_interfaces = $myhostname 147#inet_interfaces = $myhostname, localhost 148 149# NetBSD is IPv6-capable. Use all available address families. 150# 151inet_protocols = all 152 153# The proxy_interfaces parameter specifies the network interface 154# addresses that this mail system receives mail on by way of a 155# proxy or network address translation unit. This setting extends 156# the address list specified with the inet_interfaces parameter. 157# 158# You must specify your proxy/NAT addresses when your system is a 159# backup MX host for other domains, otherwise mail delivery loops 160# will happen when the primary MX host is down. 161# 162#proxy_interfaces = 163#proxy_interfaces = 1.2.3.4 164 165# The mydestination parameter specifies the list of domains that this 166# machine considers itself the final destination for. 167# 168# These domains are routed to the delivery agent specified with the 169# local_transport parameter setting. By default, that is the UNIX 170# compatible delivery agent that lookups all recipients in /etc/passwd 171# and /etc/aliases or their equivalent. 172# 173# The default is $myhostname + localhost.$mydomain + localhost. On 174# a mail domain gateway, you should also include $mydomain. 175# 176# Do not specify the names of virtual domains - those domains are 177# specified elsewhere (see VIRTUAL_README). 178# 179# Do not specify the names of domains that this machine is backup MX 180# host for. Specify those names via the relay_domains settings for 181# the SMTP server, or use permit_mx_backup if you are lazy (see 182# STANDARD_CONFIGURATION_README). 183# 184# The local machine is always the final destination for mail addressed 185# to user@[the.net.work.address] of an interface that the mail system 186# receives mail on (see the inet_interfaces parameter). 187# 188# Specify a list of host or domain names, /file/name or type:table 189# patterns, separated by commas and/or whitespace. A /file/name 190# pattern is replaced by its contents; a type:table is matched when 191# a name matches a lookup key (the right-hand side is ignored). 192# Continue long lines by starting the next line with whitespace. 193# 194# See also below, section "REJECTING MAIL FOR UNKNOWN LOCAL USERS". 195# 196#mydestination = $myhostname, localhost.$mydomain, localhost 197#mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain 198#mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, 199# mail.$mydomain, www.$mydomain, ftp.$mydomain 200 201# REJECTING MAIL FOR UNKNOWN LOCAL USERS 202# 203# The local_recipient_maps parameter specifies optional lookup tables 204# with all names or addresses of users that are local with respect 205# to $mydestination, $inet_interfaces or $proxy_interfaces. 206# 207# If this parameter is defined, then the SMTP server will reject 208# mail for unknown local users. This parameter is defined by default. 209# 210# To turn off local recipient checking in the SMTP server, specify 211# local_recipient_maps = (i.e. empty). 212# 213# The default setting assumes that you use the default Postfix local 214# delivery agent for local delivery. You need to update the 215# local_recipient_maps setting if: 216# 217# - You define $mydestination domain recipients in files other than 218# /etc/passwd, /etc/aliases, or the $virtual_alias_maps files. 219# For example, you define $mydestination domain recipients in 220# the $virtual_mailbox_maps files. 221# 222# - You redefine the local delivery agent in master.cf. 223# 224# - You redefine the "local_transport" setting in main.cf. 225# 226# - You use the "luser_relay", "mailbox_transport", or "fallback_transport" 227# feature of the Postfix local delivery agent (see local(8)). 228# 229# Details are described in the LOCAL_RECIPIENT_README file. 230# 231# Beware: if the Postfix SMTP server runs chrooted, you probably have 232# to access the passwd file via the proxymap service, in order to 233# overcome chroot restrictions. The alternative, having a copy of 234# the system passwd file in the chroot jail is just not practical. 235# 236# The right-hand side of the lookup tables is conveniently ignored. 237# In the left-hand side, specify a bare username, an @domain.tld 238# wild-card, or specify a user@domain.tld address. 239# 240#local_recipient_maps = unix:passwd.byname $alias_maps 241#local_recipient_maps = proxy:unix:passwd.byname $alias_maps 242#local_recipient_maps = 243 244# The unknown_local_recipient_reject_code specifies the SMTP server 245# response code when a recipient domain matches $mydestination or 246# ${proxy,inet}_interfaces, while $local_recipient_maps is non-empty 247# and the recipient address or address local-part is not found. 248# 249# The default setting is 550 (reject mail) but it is safer to start 250# with 450 (try again later) until you are certain that your 251# local_recipient_maps settings are OK. 252# 253unknown_local_recipient_reject_code = 550 254 255# TRUST AND RELAY CONTROL 256 257# The mynetworks parameter specifies the list of "trusted" SMTP 258# clients that have more privileges than "strangers". 259# 260# In particular, "trusted" SMTP clients are allowed to relay mail 261# through Postfix. See the smtpd_recipient_restrictions parameter 262# in postconf(5). 263# 264# You can specify the list of "trusted" network addresses by hand 265# or you can let Postfix do it for you (which is the default). 266# 267# By default (mynetworks_style = host), Postfix "trusts" only 268# the local machine. 269# 270# Specify "mynetworks_style = subnet" when Postfix should "trust" 271# SMTP clients in the same IP subnetworks as the local machine. 272# On Linux, this works correctly only with interfaces specified 273# with the "ifconfig" or "ip" command. 274# 275# Specify "mynetworks_style = class" when Postfix should "trust" SMTP 276# clients in the same IP class A/B/C networks as the local machine. 277# Don't do this with a dialup site - it would cause Postfix to "trust" 278# your entire provider's network. Instead, specify an explicit 279# mynetworks list by hand, as described below. 280# 281# Specify "mynetworks_style = host" when Postfix should "trust" 282# only the local machine. 283# 284#mynetworks_style = class 285#mynetworks_style = subnet 286#mynetworks_style = host 287 288# Alternatively, you can specify the mynetworks list by hand, in 289# which case Postfix ignores the mynetworks_style setting. 290# 291# Specify an explicit list of network/netmask patterns, where the 292# mask specifies the number of bits in the network part of a host 293# address. 294# 295# You can also specify the absolute pathname of a pattern file instead 296# of listing the patterns here.
