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

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

+# Specify your host's canonical name here. This should normally be the fully
+# qualified "official" name of your host. If this option is not set, the
+# uname() function is called to obtain the name. In many cases this does
+# the right thing and you need not set anything explicitly.
+
+primary_hostname = <%= node[:fqdn] %>
+
+
+# The next three settings create two lists of domains and one list of hosts.
+# These lists are referred to later in this configuration using the syntax
+# +local_domains, +relay_to_domains, and +relay_from_hosts, respectively. They
+# are all colon-separated lists:
+
+domainlist local_domains = <%= node[:exim][:local_domains].join(" : ") %>
+domainlist relay_to_domains = <%= @relay_to_domains.join(" : ") %>
+hostlist relay_from_hosts = <; <%= @relay_from_hosts.join(" ; ") %>
+
+# Most straightforward access control requirements can be obtained by
+# appropriate settings of the above options. In more complicated situations,
+# you may need to modify the Access Control Lists (ACLs) which appear later in
+# this file.
+
+# The first setting specifies your local domains, for example:
+#
+# domainlist local_domains = my.first.domain : my.second.domain
+#
+# You can use "@" to mean "the name of the local host", as in the default
+# setting above. This is the name that is specified by primary_hostname,
+# as specified above (or defaulted). If you do not want to do any local
+# deliveries, remove the "@" from the setting above. If you want to accept mail
+# addressed to your host's literal IP address, for example, mail addressed to
+# "user@[192.168.23.44]", you can add "@[]" as an item in the local domains
+# list. You also need to uncomment "allow_domain_literals" below. This is not
+# recommended for today's Internet.
+
+# The second setting specifies domains for which your host is an incoming relay.
+# If you are not doing any relaying, you should leave the list empty. However,
+# if your host is an MX backup or gateway of some kind for some domains, you
+# must set relay_to_domains to match those domains. For example:
+#
+# domainlist relay_to_domains = *.myco.com : my.friend.org
+#
+# This will allow any host to relay through your host to those domains.
+# See the section of the manual entitled "Control of relaying" for more
+# information.
+
+# The third setting specifies hosts that can use your host as an outgoing relay
+# to any other host on the Internet. Such a setting commonly refers to a
+# complete local network as well as the localhost. For example:
+#
+# hostlist relay_from_hosts = 127.0.0.1 : 192.168.0.0/16
+#
+# The "/16" is a bit mask (CIDR notation), not a number of hosts. Note that you
+# have to include 127.0.0.1 if you want to allow processes on your host to send
+# SMTP mail by using the loopback address. A number of MUAs use this method of
+# sending mail.
+
+# All three of these lists may contain many different kinds of item, including
+# wildcarded names, regular expressions, and file lookups. See the reference
+# manual for details. The lists above are used in the access control lists for
+# checking incoming messages. The names of these ACLs are defined here:
+
+acl_smtp_rcpt = acl_check_rcpt

+# FIXED_NEVER_USERS setting in the configuration for building Exim. The list of
+# users that it specifies is built into the binary, and cannot be changed. The
+# option below just adds additional users to the list. The default for
+# FIXED_NEVER_USERS is "root", but just to be absolutely sure, the default here

+ # The following section of the ACL is concerned with local parts that contain
+ # @ or % or ! or / or | or dots in unusual places.
+ #
+ # The characters other than dots are rarely found in genuine local parts, but
+ # are often tried by people looking to circumvent relaying restrictions.
+ # Therefore, although they are valid in local parts, these rules lock them
+ # out, as a precaution.
+ #
+ # Empty components (two dots in a row) are not valid in RFC 2822, but Exim
+ # allows them because they have been encountered. (Consider local parts
+ # constructed as "firstinitial.secondinitial.familyname" when applied to
+ # someone like me, who has no second initial.) However, a local part starting
+ # with a dot or containing /../ can cause trouble if it is used as part of a
+ # file name (e.g. for a mailing list). This is also true for local parts that
+ # contain slashes. A pipe symbol can also be troublesome if the local part is
+ # incorporated unthinkingly into a shell command line.
+ #
+ # Two different rules are used. The first one is stricter, and is applied to
+ # messages that are addressed to one of the local domains handled by this
+ # host. The line "domains = +local_domains" restricts it to domains that are
+ # defined by the "domainlist local_domains" setting above. The rule blocks

+ # the "domainlist local_domains" setting above. The exclamation mark is a
+ # negating operator. This rule allows your own users to send outgoing
+ # messages to sites that use slashes and vertical bars in their local parts.
+ # It blocks local parts that begin with a dot, slash, or vertical bar, but
+ # allows these characters within the local part. However, the sequence /../

+begin retry
+
+# This single retry rule applies to all domains and all errors. It specifies
+# retries every 15 minutes for 2 hours, then increasing retry intervals,
+# starting at 1 hour and increasing each time by a factor of 1.5, up to 16
+# hours, then retries every 6 hours until 4 days have passed since the first
+# failed delivery.
+
+# WARNING: If you do not have any retry rules at all (this section of the
+# configuration is non-existent or empty), Exim will not do any retries of
+# messages that fail to get delivered at the first attempt. The effect will
+# be to treat temporary errors as permanent. Therefore, DO NOT remove this

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