This file lists only a subset 2 # of all parameters. For the syntax, and for a complete parameter 3 # list, see the postconf(5) manual page (command: "man 5 postconf"). 4 # 5 # For common configuration examples, see BASIC_CONFIGURATION_README 6 # and STANDARD_CONFIGURATION_README. To find these documents, use 7 # the command "postconf html_directory readme_directory", or go to 8 # http://www.postfix.org/. 9 # 10 # For best results, change no more than 2-3 parameters at a time, 11 # and test if Postfix still works after every change. 12 13 # SOFT BOUNCE 14 # 15 # The soft_bounce parameter provides a limited safety net for 16 # testing. When soft_bounce is enabled, mail will remain queued that 17 # would otherwise bounce. This parameter disables locally-generated 18 # bounces, and prevents the SMTP server from rejecting mail permanently 19 # (by changing 5xx replies into 4xx replies). However, soft_bounce 20 # is no cure for address rewriting mistakes or mail routing mistakes. 21 # 22 #soft_bounce = no 23 24 # LOCAL PATHNAME INFORMATION 25 # 26 # The queue_directory specifies the location of the Postfix queue. 27 # This is also the root directory of Postfix daemons that run chrooted. 28 # See the files in examples/chroot-setup for setting up Postfix chroot 29 # environments on different UNIX systems. 30 # 31 queue_directory = /var/spool/postfix 32 33 # The command_directory parameter specifies the location of all 34 # postXXX commands. 35 # 36 command_directory = /usr/sbin 37 38 # The daemon_directory parameter specifies the location of all Postfix 39 # daemon programs (i.e. programs listed in the master.cf file). This 40 # directory must be owned by root. 41 # 42 daemon_directory = /usr/libexec/postfix 43 44 # The data_directory parameter specifies the location of Postfix-writable 45 # data files (caches, random numbers). This directory must be owned 46 # by the mail_owner account (see below). 47 # 48 data_directory = /var/lib/postfix 49 50 # QUEUE AND PROCESS OWNERSHIP 51 # 52 # The mail_owner parameter specifies the owner of the Postfix queue 53 # and of most Postfix daemon processes. Specify the name of a user 54 # account THAT DOES NOT SHARE ITS USER OR GROUP ID WITH OTHER ACCOUNTS 55 # AND THAT OWNS NO OTHER FILES OR PROCESSES ON THE SYSTEM. In 56 # particular, don't specify nobody or daemon. PLEASE USE A DEDICATED 57 # USER. 58 # 59 mail_owner = postfix 60 61 # The default_privs parameter specifies the default rights used by 62 # the local delivery agent for delivery to external file or command. 63 # These rights are used in the absence of a recipient user context. 64 # DO NOT SPECIFY A PRIVILEGED USER OR THE POSTFIX OWNER. 65 # 66 #default_privs = nobody 67 68 # INTERNET HOST AND DOMAIN NAMES 69 # 70 # The myhostname parameter specifies the internet hostname of this 71 # mail system.

The default is to append $myhostname, 90 # which is fine for small sites. If you run a domain with multiple 91 # machines, you should (1) change this to $mydomain and (2) set up 92 # a domain-wide alias database that aliases each user to 93 # user@that.users.mailhost. 94 # 95 # For the sake of consistency between sender and recipient addresses, 96 # myorigin also specifies the default domain name that is appended 97 # to recipient addresses that have no @domain part. 98 # 99 #myorigin = $myhostname 100 myorigin = $mydomain 101 102 # RECEIVING MAIL 103 104 # The inet_interfaces parameter specifies the network interface 105 # addresses that this mail system receives mail on.

This setting extends 124 # the address list specified with the inet_interfaces parameter. 125 # 126 # You must specify your proxy/NAT addresses when your system is a 127 # backup MX host for other domains, otherwise mail delivery loops 128 # will happen when the primary MX host is down. 129 # 130 #proxy_interfaces = 131 #proxy_interfaces = 1.2.3.4 132 133 # The mydestination parameter specifies the list of domains that this 134 # machine considers itself the final destination for. 135 # 136 # These domains are routed to the delivery agent specified with the 137 # local_transport parameter setting. By default, that is the UNIX 138 # compatible delivery agent that lookups all recipients in /etc/passwd 139 # and /etc/aliases or their equivalent. 140 # 141 # The default is $myhostname + localhost.$mydomain. On a mail domain 142 # gateway, you should also include $mydomain. 143 # 144 # Do not specify the names of virtual domains - those domains are 145 # specified elsewhere (see VIRTUAL_README). 146 # 147 # Do not specify the names of domains that this machine is backup MX 148 # host for.

A /file/name 158 # pattern is replaced by its contents; a type:table is matched when 159 # a name matches a lookup key (the right-hand side is ignored). 160 # Continue long lines by starting the next line with whitespace. 161 # 162 # See also below, section "REJECTING MAIL FOR UNKNOWN LOCAL USERS". 163 # 164 mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain 165 #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain 166 #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, 167 # mail.$mydomain, www.$mydomain, ftp.$mydomain 168 169 # REJECTING MAIL FOR UNKNOWN LOCAL USERS 170 # 171 # The local_recipient_maps parameter specifies optional lookup tables 172 # with all names or addresses of users that are local with respect 173 # to $mydestination, $inet_interfaces or $proxy_interfaces. 174 # 175 # If this parameter is defined, then the SMTP server will reject 176 # mail for unknown local users. This parameter is defined by default. 177 # 178 # To turn off local recipient checking in the SMTP server, specify 179 # local_recipient_maps = (i.e. empty). 180 # 181 # The default setting assumes that you use the default Postfix local 182 # delivery agent for local delivery. You need to update the 183 # local_recipient_maps setting if: 184 # 185 # - You define $mydestination domain recipients in files other than 186 # /etc/passwd, /etc/aliases, or the $virtual_alias_maps files. 187 # For example, you define $mydestination domain recipients in 188 # the $virtual_mailbox_maps files. 189 # 190 # - You redefine the local delivery agent in master.cf. 191 # 192 # - You redefine the "local_transport" setting in main.cf. 193 # 194 # - You use the "luser_relay", "mailbox_transport", or "fallback_transport" 195 # feature of the Postfix local delivery agent (see local(8)). 196 # 197 # Details are described in the LOCAL_RECIPIENT_README file. 198 # 199 # Beware: if the Postfix SMTP server runs chrooted, you probably have 200 # to access the passwd file via the proxymap service, in order to 201 # overcome chroot restrictions. The alternative, having a copy of 202 # the system passwd file in the chroot jail is just not practical. 203 # 204 # The right-hand side of the lookup tables is conveniently ignored. 205 # In the left-hand side, specify a bare username, an @domain.tld 206 # wild-card, or specify a user@domain.tld address. 207 # 208 #local_recipient_maps = unix:passwd.byname $alias_maps 209 #local_recipient_maps = proxy:unix:passwd.byname $alias_maps 210 #local_recipient_maps = 211 212 # The unknown_local_recipient_reject_code specifies the SMTP server 213 # response code when a recipient domain matches $mydestination or 214 # ${proxy,inet}_interfaces, while $local_recipient_maps is non-empty 215 # and the recipient address or address local-part is not found. 216 # 217 # The default setting is 550 (reject mail) but it is safer to start 218 # with 450 (try again later) until you are certain that your 219 # local_recipient_maps settings are OK. 220 # 221 unknown_local_recipient_reject_code = 550 222 223 # TRUST AND RELAY CONTROL 224 225 # The mynetworks parameter specifies the list of "trusted" SMTP 226 # clients that have more privileges than "strangers". 227 # 228 # In particular, "trusted" SMTP clients are allowed to relay mail 229 # through Postfix. See the smtpd_recipient_restrictions parameter 230 # in postconf(5). 231 # 232 # You can specify the list of "trusted" network addresses by hand 233 # or you can let Postfix do it for you (which is the default). 234 # 235 # By default (mynetworks_style = subnet), Postfix "trusts" SMTP 236 # clients in the same IP subnetworks as the local machine. 237 # On Linux, this does works correctly only with interfaces specified 238 # with the "ifconfig" command. 239 # 240 # Specify "mynetworks_style = class" when Postfix should "trust" SMTP 241 # clients in the same IP class A/B/C networks as the local machine. 242 # Don't do this with a dialup site - it would cause Postfix to "trust" 243 # your entire provider's network.
