+# 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 =
+
+
+# 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 = @
+domainlist relay_to_domains =
+hostlist   relay_from_hosts = localhost
+# (We rely upon hostname resolution working for localhost, because the default
+# uncommented configuration needs to work in IPv4-only environments.)
+
+# 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 ; ::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.  Often, connections are made to "localhost", which might be ::1
+# on IPv6-enabled hosts.  Do not forget CIDR for your IPv6 networks.
+
+# 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
+acl_smtp_data = acl_check_data
+
+# You should not change those settings until you understand how ACLs work.
+
+
+# If you are running a version of Exim that was compiled with the content-
+# scanning extension, you can cause incoming messages to be automatically
+# scanned for viruses. You have to modify the configuration in two places to
+# set this up. The first of them is here, where you define the interface to
+# your scanner. This example is typical for ClamAV; see the manual for details
+# of what to set for other virus scanners. The second modification is in the
+# acl_check_data access control list (see below).
+
+# av_scanner = clamd:/run/clamav/clamd.sock
+
+
+# For spam scanning, there is a similar option that defines the interface to
+# SpamAssassin. You do not need to set this if you are using the default, which
+# is shown in this commented example. As for virus scanning, you must also
+# modify the acl_check_data access control list to enable spam scanning.
+
+# spamd_address = 127.0.0.1 783
+# spamd_address = 127.0.0.1 11333 variant=rspamd
+
+
+# If Exim is compiled with support for TLS, you may want to enable the
+# following options so that Exim allows clients to make encrypted
+# connections. In the authenticators section below, there are template
+# configurations for plaintext username/password authentication. This kind
+# of authentication is only safe when used within a TLS connection, so the
+# authenticators will only work if the following TLS settings are turned on
+# as well.
+
+# Allow any client to use TLS.
+
+# tls_advertise_hosts = *
+
+# Specify the location of the Exim server's TLS certificate and private key.
+# The private key must not be encrypted (password protected). You can put
+# the certificate and private key in the same file, in which case you only
+# need the first setting, or in separate files, in which case you need both
+# options.
+
+# tls_certificate = /etc/ssl/exim.crt
+# tls_privatekey = /etc/ssl/exim.pem
+
+# In order to support roaming users who wish to send email from anywhere,
+# you may want to make Exim listen on other ports as well as port 25, in
+# case these users need to send email from a network that blocks port 25.
+# The standard port for this purpose is port 587, the "message submission"
+# port. See RFC 4409 for details. Microsoft MUAs cannot be configured to
+# talk the message submission protocol correctly, so if you need to support
+# them you should also allow TLS-on-connect on the traditional but
+# non-standard port 465.
+
+# daemon_smtp_ports = 25 : 465 : 587
+# tls_on_connect_ports = 465
+
+
+# Specify the domain you want to be added to all unqualified addresses
+# here. An unqualified address is one that does not contain an "@" character
+# followed by a domain. For example, "caesar@rome.example" is a fully qualified
+# address, but the string "caesar" (i.e. just a login name) is an unqualified
+# email address. Unqualified addresses are accepted only from local callers by
+# default. See the recipient_unqualified_hosts option if you want to permit
+# unqualified addresses from remote sources. If this option is not set, the
+# primary_hostname value is used for qualification.
+
+# qualify_domain =
+
+
+# If you want unqualified recipient addresses to be qualified with a different
+# domain to unqualified sender addresses, specify the recipient domain here.
+# If this option is not set, the qualify_domain value is used.
+
+# qualify_recipient =
+
+
+# The following line must be uncommented if you want Exim to recognize
+# addresses of the form "user@[10.11.12.13]" that is, with a "domain literal"
+# (an IP address) instead of a named domain. The RFCs still require this form,
+# but it makes little sense to permit mail to be sent to specific hosts by
+# their IP address in the modern Internet. This ancient format has been used
+# by those seeking to abuse hosts by using them for unwanted relaying. If you
+# really do want to support domain literals, uncomment the following line, and
+# see also the "domain_literal" router below.
+
+# allow_domain_literals
+
+
+# No deliveries will ever be run under the uids of users specified by
+# never_users (a colon-separated list). An attempt to do so causes a panic
+# error to be logged, and the delivery to be deferred. This is a paranoic
+# safety catch. There is an even stronger safety catch in the form of the
+# 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
+# is also "root".
+
+# Note that the default setting means you cannot deliver mail addressed to root
+# as if it were a normal user. This isn't usually a problem, as most sites have
+# an alias for root that redirects such mail to a human administrator.
+
+never_users = root
+
+
+# The setting below causes Exim to do a reverse DNS lookup on all incoming
+# IP calls, in order to get the true host name. If you feel this is too
+# expensive, you can specify the networks for which a lookup is done, or
+# remove the setting entirely.

+# The settings below cause Exim to make RFC 1413 (ident) callbacks
+# for all incoming SMTP calls. You can limit the hosts to which these
+# calls are made, and/or change the timeout that is used. If you set
+# the timeout to zero, all RFC 1413 calls are disabled. RFC 1413 calls
+# are cheap and can provide useful information for tracing problem
+# messages, but some hosts and firewalls have problems with them.
+# This can result in a timeout instead of an immediate refused
+# connection, leading to delays on starting up SMTP sessions.
+# (The default was reduced from 30s to 5s for release 4.61. and to
+# disabled for release 4.86)

+# By default, Exim expects all envelope addresses to be fully qualified, that
+# is, they must contain both a local part and a domain. If you want to accept

+# these hosts by setting one or both of
+#
+# sender_unqualified_hosts =
+# recipient_unqualified_hosts =
+#
+# to control sender and recipient addresses, respectively. When this is done,
+# unqualified addresses are qualified using the settings of qualify_domain
