  1. # Global Postfix configuration file. 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/BASIC_CONFIGURATION_README.html etc.
  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. # COMPATIBILITY
  13. #
  14. # The compatibility_level determines what default settings Postfix
  15. # will use for main.cf and master.cf settings. These defaults will
  16. # change over time.
  17. #
  18. # To avoid breaking things, Postfix will use backwards-compatible
  19. # default settings and log where it uses those old backwards-compatible
  20. # default settings, until the system administrator has determined
  21. # if any backwards-compatible default settings need to be made
  22. # permanent in main.cf or master.cf.
  23. #
  24. # When this review is complete, update the compatibility_level setting
  25. # below as recommended in the RELEASE_NOTES file.
  26. #
  27. # The level below is what should be used with new (not upgrade) installs.

  30. # SOFT BOUNCE
  31. #
  32. # The soft_bounce parameter provides a limited safety net for
  33. # testing. When soft_bounce is enabled, mail will remain queued that
  34. # would otherwise bounce. This parameter disables locally-generated
  35. # bounces, and prevents the SMTP server from rejecting mail permanently
  36. # (by changing 5xx replies into 4xx replies). However, soft_bounce
  37. # is no cure for address rewriting mistakes or mail routing mistakes.

  99. # a domain-wide alias database that aliases each user to
  100. # user@that.users.mailhost.

  124. # proxy or network address translation unit. This setting extends
  125. # the address list specified with the inet_interfaces parameter.

  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 + localhost. On
  142. # a mail domain gateway, you should also include $mydomain.

  147. # Do not specify the names of domains that this machine is backup MX
  148. # host for. Specify those names via the relay_domains settings for

  179. #
  180. # The default setting assumes that you use the default Postfix local
  181. # delivery agent for local delivery. You need to update the
  182. # local_recipient_maps setting if:
  183. #
  184. # - You define $mydestination domain recipients in files other than
  185. # /etc/passwd, /etc/aliases, or the $virtual_alias_maps files.
  186. # For example, you define $mydestination domain recipients in
  187. # the $virtual_mailbox_maps files.
  188. #
  189. # - You redefine the local delivery agent in master.cf.
  190. #
  191. # - You redefine the "local_transport" setting in main.cf.
  192. #
  193. # - You use the "luser_relay", "mailbox_transport", or "fallback_transport"
  194. # feature of the Postfix local delivery agent (see local(8)).

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

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

  272. # In addition to the above, the Postfix SMTP server by default accepts mail
  273. # that Postfix is final destination for:
  274. # - destinations that match $inet_interfaces or $proxy_interfaces,
  275. # - destinations that match $mydestination
  276. # - destinations that match $virtual_alias_domains,
  277. # - destinations that match $virtual_mailbox_domains.
  278. # These destinations do not need to be listed in $relay_domains.

  281. # lookup tables, separated by commas and/or whitespace. Continue

  283. # is replaced by its contents; a type:name table is matched when a
  284. # (parent) domain appears as lookup key.
  285. #
  286. # NOTE: Postfix will not automatically forward mail for domains that
  287. # list this system as their primary or backup MX host. See the

  297. # internal DNS uses no MX records, specify the name of the intranet
  298. # gateway host instead.
  299. #
  300. # In the case of SMTP, specify a domain, host, host:port, [host]:port,
  301. # [address] or [address]:port; the form [host] turns off MX lookups.

  328. # to an SCO bug).
  329. #
  330. # A Postfix process will pause for $in_flow_delay seconds before
  331. # accepting a new message, when the message arrival rate exceeds the
  332. # message delivery rate. With the default 100 SMTP server process

  363. # If you change the alias database, run "postalias /etc/aliases" (or

  521. # the mail version advertised. By default, Postfix shows no version.

  532. # to the same user, because mailbox updates must happen sequentially,
