  2. # Global Postfix configuration file. This file lists only a subset
  3. # of all parameters. For the syntax, and for a complete parameter
  4. # list, see the postconf(5) manual page (command: "man 5 postconf").
  5. #
  6. # For common configuration examples, see BASIC_CONFIGURATION_README
  7. # and STANDARD_CONFIGURATION_README. To find these documents, use
  8. # the command "postconf html_directory readme_directory", or go to
  9. # http://www.postfix.org/BASIC_CONFIGURATION_README.html etc.
  10. #
  11. # For best results, change no more than 2-3 parameters at a time,
  12. # and test if Postfix still works after every change.
  13. # COMPATIBILITY
  14. #
  15. # The compatibility_level determines what default settings Postfix
  16. # will use for main.cf and master.cf settings. These defaults will
  17. # change over time.
  18. #
  19. # To avoid breaking things, Postfix will use backwards-compatible
  20. # default settings and log where it uses those old backwards-compatible
  21. # default settings, until the system administrator has determined
  22. # if any backwards-compatible default settings need to be made
  23. # permanent in main.cf or master.cf.
  24. #
  25. # When this review is complete, update the compatibility_level setting
  26. # below as recommended in the RELEASE_NOTES file.
  27. #
  28. # The level below is what should be used with new (not upgrade) installs.
  29. #
  30. #compatibility_level = 2
  31. # SOFT BOUNCE
  32. #
  33. # The soft_bounce parameter provides a limited safety net for
  34. # testing. When soft_bounce is enabled, mail will remain queued that
  35. # would otherwise bounce. This parameter disables locally-generated
  36. # bounces, and prevents the SMTP server from rejecting mail permanently
  37. # (by changing 5xx replies into 4xx replies). However, soft_bounce
  38. # is no cure for address rewriting mistakes or mail routing mistakes.
  39. #
  40. #soft_bounce = no
  41. # LOCAL PATHNAME INFORMATION
  42. #
  43. # The queue_directory specifies the location of the Postfix queue.

  53. # The daemon_directory parameter specifies the location of all Postfix
  54. # daemon programs (i.e. programs listed in the master.cf file). This
  55. # directory must be owned by root.
  56. #
  57. daemon_directory = /usr/libexec/postfix
  58. # The data_directory parameter specifies the location of Postfix-writable

  61. #
  62. data_directory = /var/lib/postfix
  63. # QUEUE AND PROCESS OWNERSHIP
  64. #
  65. # The mail_owner parameter specifies the owner of the Postfix queue
  66. # and of most Postfix daemon processes. Specify the name of a user
  67. # account THAT DOES NOT SHARE ITS USER OR GROUP ID WITH OTHER ACCOUNTS
  68. # AND THAT OWNS NO OTHER FILES OR PROCESSES ON THE SYSTEM. In
  69. # particular, don't specify nobody or daemon. PLEASE USE A DEDICATED
  70. # USER.
  71. #
  72. mail_owner = postfix
  73. # The default_privs parameter specifies the default rights used by
  74. # the local delivery agent for delivery to external file or command.
  75. # These rights are used in the absence of a recipient user context.
  76. # DO NOT SPECIFY A PRIVILEGED USER OR THE POSTFIX OWNER.
  77. #
  78. #default_privs = nobody
  79. # INTERNET HOST AND DOMAIN NAMES
  80. #
  81. # The myhostname parameter specifies the internet hostname of this
  82. # mail system. The default is to use the fully-qualified domain name
  83. # from gethostname(). $myhostname is used as a default value for many
  84. # other configuration parameters.
  85. #
  86. myhostname = kerrhau.cf
  87. #myhostname = virtual.domain.tld
  88. # The mydomain parameter specifies the local internet domain name.
  89. # The default is to use $myhostname minus the first component.
  90. # $mydomain is used as a default value for many other configuration
  91. # parameters.
  92. #
  93. #mydomain = domain.tld
  94. # SENDING MAIL
  95. #
  96. # The myorigin parameter specifies the domain that locally-posted
  97. # mail appears to come from. The default is to append $myhostname,
  98. # which is fine for small sites. If you run a domain with multiple
  99. # machines, you should (1) change this to $mydomain and (2) set up
  100. # a domain-wide alias database that aliases each user to
  101. # user@that.users.mailhost.
  102. #
  103. # For the sake of consistency between sender and recipient addresses,
  104. # myorigin also specifies the default domain name that is appended
  105. # to recipient addresses that have no @domain part.

  108. #myorigin = $mydomain
  109. # RECEIVING MAIL
  110. # The inet_interfaces parameter specifies the network interface
  111. # addresses that this mail system receives mail on. By default,
  112. # the software claims all active interfaces on the machine. The
  113. # parameter also controls delivery of mail to user@[ip.address].
  114. #
  115. # See also the proxy_interfaces parameter, for network addresses that
  116. # are forwarded to us via a proxy or network address translator.
  117. #
  118. # Note: you need to stop/start Postfix when this parameter changes.
  119. #
  120. #inet_interfaces = all
  121. #inet_interfaces = $myhostname
  122. #inet_interfaces = $myhostname, localhost
  123. # The proxy_interfaces parameter specifies the network interface
  124. # addresses that this mail system receives mail on by way of a
  125. # proxy or network address translation unit. This setting extends
  126. # the address list specified with the inet_interfaces parameter.
  127. #
  128. # You must specify your proxy/NAT addresses when your system is a
  129. # backup MX host for other domains, otherwise mail delivery loops
  130. # will happen when the primary MX host is down.
  131. #
  132. #proxy_interfaces =
  133. #proxy_interfaces = 1.2.3.4
  134. # The mydestination parameter specifies the list of domains that this
  135. # machine considers itself the final destination for.
  136. #
  137. # These domains are routed to the delivery agent specified with the
  138. # local_transport parameter setting. By default, that is the UNIX
  139. # compatible delivery agent that lookups all recipients in /etc/passwd
  140. # and /etc/aliases or their equivalent.
  141. #
  142. # The default is $myhostname + localhost.$mydomain + localhost. On
  143. # a mail domain gateway, you should also include $mydomain.
  144. #
  145. # Do not specify the names of virtual domains - those domains are
  146. # specified elsewhere (see VIRTUAL_README).
  147. #
  148. # Do not specify the names of domains that this machine is backup MX
  149. # host for. Specify those names via the relay_domains settings for
  150. # the SMTP server, or use permit_mx_backup if you are lazy (see
  151. # STANDARD_CONFIGURATION_README).
  152. #
  153. # The local machine is always the final destination for mail addressed
  154. # to user@[the.net.work.address] of an interface that the mail system
  155. # receives mail on (see the inet_interfaces parameter).
  156. #
  157. # Specify a list of host or domain names, /file/name or type:table
  158. # patterns, separated by commas and/or whitespace. A /file/name
  159. # pattern is replaced by its contents; a type:table is matched when
  160. # a name matches a lookup key (the right-hand side is ignored).

  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. #

  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

  221. # TRUST AND RELAY CONTROL
  222. # The mynetworks parameter specifies the list of "trusted" SMTP
  223. # clients that have more privileges than "strangers".
  224. #
  225. # In particular, "trusted" SMTP clients are allowed to relay mail
  226. # through Postfix. See the smtpd_recipient_restrictions parameter
  227. # in postconf(5).
  228. #
  229. # You can specify the list of "trusted" network addresses by hand
  230. # or you can let Postfix do it for you (which is the default).
  231. #
  232. # By default (mynetworks_style = subnet), Postfix "trusts" SMTP
  233. # clients in the same IP subnetworks as the local machine.
  234. # On Linux, this does works correctly only with interfaces specified
  235. # with the "ifconfig" command.
  236. #
  237. # Specify "mynetworks_style = class" when Postfix should "trust" SMTP
  238. # clients in the same IP class A/B/C networks as the local machine.
  239. # Don't do this with a dialup site - it would cause Postfix to "trust"
  240. # your entire provider's network. Instead, specify an explicit
  241. # mynetworks list by hand, as described below.

  250. # which case Postfix ignores the mynetworks_style setting.
  251. #
  252. # Specify an explicit list of network/netmask patterns, where the
  253. # mask specifies the number of bits in the network part of a host
  254. # address.
  255. #
  256. # You can also specify the absolute pathname of a pattern file instead
  257. # of listing the patterns here. Specify type:table for table-based lookups

  285. # (parent) domain appears as lookup key.
  286. #
  287. # NOTE: Postfix will not automatically forward mail for domains that

  300. #
  301. # In the case of SMTP, specify a domain, host, host:port, [host]:port,
