# 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 #

# 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 #

# MAIN CONFIGURATION SETTINGS #
|
|
######################################################################
|
|
|
|
# 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 = @<% if mailman_domains.length > 0 -%>:<%= mailman_domains.join(":") %><% end -%>
|
|
|
|
domainlist relay_to_domains =
|
|
hostlist relay_from_hosts = 127.0.0.1
|
|
|
|
# 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
|
|
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:/tmp/clamd
|
|
|
|
|
|
# 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.

# 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.

|
|
# 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

# 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
|
|

|
# (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

|
# 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

# 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
|
|
# local parts that begin with a dot or contain @ % ! / or |. If you have

|
# local accounts that include these characters, you will have to modify this

# rule.

|
# "domains = !+local_domains" restricts it to domains that are NOT defined by
|
|
# 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 /../
|
