8 # This is a default configuration file which will operate correctly in
9 # uncomplicated installations. Please see the manual for a complete list
10 # of all the runtime configuration options that can be included in a
11 # configuration file. There are many more than are mentioned here. The
12 # manual is in the file doc/spec.txt in the Exim distribution as a plain
13 # ASCII file. Other formats (PostScript, Texinfo, HTML, PDF) are available
14 # from the Exim ftp sites. The manual is also online at the Exim web sites.
17 # This file is divided into several parts, all but the first of which are
18 # headed by a line starting with the word "begin". Only those parts that
19 # are required need to be present. Blank lines, and lines starting with #

25 # Whenever you change Exim's configuration file, you *must* remember to #
26 # HUP the Exim daemon, because it will not pick up the new configuration #
27 # until you do. However, any other Exim processes that are started, for #
28 # example, a process started by an MUA in order to send a message, will #
29 # see the new configuration as soon as it is in place. #
31 # You do not need to HUP the daemon for changes in auxiliary files that #
32 # are referenced from this file. They are read every time they are used. #
34 # It is usually a good idea to test a new configuration for syntactic #
35 # correctness before installing it (for example, by running the command #
36 # "exim -C /config/file.new -bV"). #

43 # MAIN CONFIGURATION SETTINGS #
44 ######################################################################
47 # Specify your host's canonical name here. This should normally be the fully
48 # qualified "official" name of your host. If this option is not set, the
49 # uname() function is called to obtain the name. In many cases this does
50 # the right thing and you need not set anything explicitly.
52 primary_hostname = <%= node[:fqdn] %>
55 # The next three settings create two lists of domains and one list of hosts.
56 # These lists are referred to later in this configuration using the syntax
57 # +local_domains, +relay_to_domains, and +relay_from_hosts, respectively. They
58 # are all colon-separated lists:
60 domainlist local_domains = <%= node[:exim][:local_domains].join(" : ") %>
61 domainlist relay_to_domains = <%= @relay_to_domains.join(" : ") %>
62 hostlist relay_from_hosts = <; <%= @relay_from_hosts.join(" ; ") %>
64 # Most straightforward access control requirements can be obtained by
65 # appropriate settings of the above options. In more complicated situations,
66 # you may need to modify the Access Control Lists (ACLs) which appear later in
69 # The first setting specifies your local domains, for example:
71 # domainlist local_domains = my.first.domain : my.second.domain
73 # You can use "@" to mean "the name of the local host", as in the default
74 # setting above. This is the name that is specified by primary_hostname,
75 # as specified above (or defaulted). If you do not want to do any local
76 # deliveries, remove the "@" from the setting above. If you want to accept mail
77 # addressed to your host's literal IP address, for example, mail addressed to
78 # "user@[192.168.23.44]", you can add "@[]" as an item in the local domains
79 # list. You also need to uncomment "allow_domain_literals" below. This is not
80 # recommended for today's Internet.
82 # The second setting specifies domains for which your host is an incoming relay.
83 # If you are not doing any relaying, you should leave the list empty. However,
84 # if your host is an MX backup or gateway of some kind for some domains, you
85 # must set relay_to_domains to match those domains. For example:
87 # domainlist relay_to_domains = *.myco.com : my.friend.org
89 # This will allow any host to relay through your host to those domains.
90 # See the section of the manual entitled "Control of relaying" for more
93 # The third setting specifies hosts that can use your host as an outgoing relay
94 # to any other host on the Internet. Such a setting commonly refers to a
95 # complete local network as well as the localhost. For example:
97 # hostlist relay_from_hosts = <; 127.0.0.1 ; ::1 ; 192.168.0.0/16
99 # The "/16" is a bit mask (CIDR notation), not a number of hosts. Note that you
100 # have to include 127.0.0.1 if you want to allow processes on your host to send
101 # SMTP mail by using the loopback address. A number of MUAs use this method of
102 # sending mail. Often, connections are made to "localhost", which might be ::1
103 # on IPv6-enabled hosts. Do not forget CIDR for your IPv6 networks.
105 # All three of these lists may contain many different kinds of item, including
106 # wildcarded names, regular expressions, and file lookups. See the reference
107 # manual for details. The lists above are used in the access control lists for
108 # checking incoming messages. The names of these ACLs are defined here:

213 # No deliveries will ever be run under the uids of users specified by

215 # error to be logged, and the delivery to be deferred. This is a paranoic
216 # safety catch. There is an even stronger safety catch in the form of the
217 # FIXED_NEVER_USERS setting in the configuration for building Exim. The list of
218 # users that it specifies is built into the binary, and cannot be changed. The

224 # as if it were a normal user. This isn't usually a problem, as most sites have
225 # an alias for root that redirects such mail to a human administrator.
230 # The setting below causes Exim to do a reverse DNS lookup on all incoming
231 # IP calls, in order to get the true host name. If you feel this is too
232 # expensive, you can specify the networks for which a lookup is done, or

241 # the timeout to zero, all RFC 1413 calls are disabled. RFC 1413 calls
242 # are cheap and can provide useful information for tracing problem

393 # The following section of the ACL is concerned with local parts that contain
394 # @ or % or ! or / or | or dots in unusual places.
396 # The characters other than dots are rarely found in genuine local parts, but
397 # are often tried by people looking to circumvent relaying restrictions.
398 # Therefore, although they are valid in local parts, these rules lock them
399 # out, as a precaution.
401 # Empty components (two dots in a row) are not valid in RFC 2822, but Exim
402 # allows them because they have been encountered. (Consider local parts
403 # constructed as "firstinitial.secondinitial.familyname" when applied to
404 # someone like me, who has no second initial.) However, a local part starting
405 # with a dot or containing /../ can cause trouble if it is used as part of a
406 # file name (e.g. for a mailing list). This is also true for local parts that
407 # contain slashes. A pipe symbol can also be troublesome if the local part is
408 # incorporated unthinkingly into a shell command line.

413 # defined by the "domainlist local_domains" setting above. The rule blocks

425 # negating operator. This rule allows your own users to send outgoing

869 # The following authenticators support plaintext username/password
870 # authentication using the standard PLAIN mechanism and the traditional
871 # but non-standard LOGIN mechanism, with Exim acting as the server.
872 # PLAIN and LOGIN are enough to support most MUA software.
874 # These authenticators are not complete: you need to change the
875 # server_condition settings to specify how passwords are verified.
876 # They are set up to offer authentication to the client only if the
877 # connection is encrypted with TLS, so you also need to add support
878 # for TLS. See the global configuration options section at the start
879 # of this file for more about TLS.
881 # The default RCPT ACL checks for successful authentication, and will accept
882 # messages from authenticated users from anywhere on the Internet.
886 # PLAIN authentication has no server prompts. The client sends its
887 # credentials in one lump, containing an authorization ID (which we do not
888 # use), an authentication ID, and a password. The latter two appear as
889 # $auth2 and $auth3 in the configuration and should be checked against a
890 # valid username and password. In a real configuration you would typically
891 # use $auth2 as a lookup key, and compare $auth3 against the result of the
892 # lookup, perhaps using the crypteq{}{} condition.
896 # server_set_id = $auth2
898 # server_condition = Authentication is not yet configured
899 # server_advertise_condition = ${if def:tls_cipher }
901 # LOGIN authentication has traditional prompts and responses. There is no
902 # authorization ID in this mechanism, so unlike PLAIN the username and
903 # password are $auth1 and $auth2. Apart from that you can use the same
904 # server_condition setting for both authenticators.
